Low risk of urinary incontinence following prostate brachytherapy in patients with a prior transurethral prostate resection

PURPOSE: To review post implant morbidity in patients with prior transurethral prostate resection (TURP). METHODS AND MATERIALS: Nineteen patients with stage T1-T2 prostatic carcinoma and prior TURP were treated with I-125 or Pd-103 implantation from 1991 through 1994. Follow-up ranged from 1 to 6 years (median: 3 years). The time from TURP to implantation ranged from 2 months to 15 years (median: 3 years). RESULTS: Only one patient developed mild urinary stress incontinence, 6 months following his I-125 implant. The actuarial freedom from permanent urinary incontinence at 3 years after implantation was 94%. No patient required urethral dilatation for urethral stricture. Eleven patients were sexually potent prior to implantation. At 3 years after treatment, all patients had maintained potency. CONCLUSION: In our experience, there has been remarkably little adverse sequelae following I-125 or Pd-103 implantation in patients with a prior history of TURP.     

Catheter-free endoscopic laser ablation of the prostate using a 1-size prostatic stent

PURPOSE: Endoscopic laser ablation of the prostate is a safe alternative to transurethral prostatic resection. Recognized disadvantages include prolonged catheterization, postoperative discomfort and delayed symptomatic improvement. We assessed the role of a 1-size temporary prostatic stent in men undergoing endoscopic laser ablation of the prostate. MATERIALS AND METHODS: A total of 55 men a mean of 73 years old with outflow obstruction, including 9 who presented in urinary retention, underwent endoscopic laser ablation of the prostate and temporary stenting. Urinary flow rate, residual urine volume, symptom score and prostate specific antigen were measured preoperatively, and 6 weeks (with the stent in situ), 3 months (after stent removal) and 12 months postoperatively. Duration of hospital stay and complications were also recorded. RESULTS: Of the 55 men 37 (67%) voided immediately with the stent in situ, including 7 of the 9 in retention. At 6 weeks with the stent in place mean maximum urine flow was 17.3 ml. per second (preoperatively 8.7). Dysuria was reported by 3 patients. Stent related complications were rare. One stent migrated early, resulting in urinary retention, while 2 that migrated late were asymptomatic. No patient had acute urinary retention after stent removal. Maximum urinary flow rate measured at 6 weeks with the stent in situ was similar to that 1 year after endoscopic laser ablation of the prostate. CONCLUSIONS: The use of a 1-size, inexpensive plastic prostatic stent enabled catheter-free endoscopic laser ablation of the prostate in 67% of our patients. Early improvements in the urinary flow rate and a lower incidence of dysuria were additional benefits. The result of endoscopic laser ablation of the prostate at 1 year was comparable to that of transurethral prostatic resection.     

Extraorganic hepatic artery aneurysm: failure of transcatheter embolization

BACKGROUND: We evaluated the safety and efficacy of transurethral electrovaporization of the prostate (TVP) as a new alternative treatment for patients with benign prostatic hyperplasia. METHODS: A total of 22 patients with symptomatic benign prostatic hyperplasia, including 4 with urinary retention, underwent TVP. If enough of a cavity was not created after 60 minutes of vaporization, transurethral resection of the prostate (TURP) was performed successively. International Prostate Symptom Score (I-PSS) with quality-of-life index, maximum flow rate, and postvoid residual volume were measured at baseline and at 2 weeks, 1, 3, and 6 months. A pressure-flow study was performed at baseline and at 3 or 6 months after surgery. RESULTS: TURP was required in 10 of 22 patients. At 6 months, mean I-PSS decreased from 20.0 to 5.2, quality-of-life index decreased from 4.6 to 1.1, mean maximum flow rate increased from 6.9 to 16.7 mL/s, and postvoid residual volume decreased from 152 to 32 mL. Detrusor pressure at maximum flow decreased from 108 to 39 cm H2O, with a significant relief of bladder outlet obstruction in 93% of the patients. Mean decrease in hematocrit was 4.4%, and in serum sodium, 4.8 mEq/L. None of the patients required transfusions or had TUR syndrome. A urethral stricture and a severe stress incontinence developed in 1 patient. CONCLUSION: TVP seems to be a safe and effective alternative to a standard TURP associated with fewer intraoperative complications. Although preliminary clinical results have been promising, further study is necessary to establish long-term efficacy and safety of this procedure.     

Catheter-free same day surgery transurethral resection of the prostate

PURPOSE: Transurethral resection of the prostate using electrocautery has long been the standard method of management of lower urinary tract obstructive symptoms. While there has been a trend towards reduced catheterization time following transurethral prostatic resection, this study outlines the methods and results of transurethral prostatic resection performed in the day surgery setting. MATERIALS AND METHODS: The study was performed at a free-standing licensed day surgical hospital serving a patient population of more than 150,000. A total of 58 patients of a mean age of 68.77 years (range 49 to 87) underwent same day conventional transurethral prostatic resection. Of the procedures 39 (67%) were performed with spinal and the remainder with general anesthesia. RESULTS: Mean overall duration of catheterization was 6.54 hours. Of the 48 patients (82.76%) undergoing single catheterization mean duration was 5.59 hours. Mean total duration of catheterization for 10 patients (17.24%) who required reinsertion of a catheter was 11.09 hours. Duration of catheterization was 7.69 hours for patients treated with spinal and 3.86 for those treated with general anesthesia. Repeat catheterization was required in 10 patients and was due to urethral discomfort in initiating micturition in 8. Postoperative urinary tract infections occurred in 2 patients. No patient was readmitted to the hospital for retention of urine but 1 was admitted to a private hospital for management of postoperative fever and 1 for monitoring of tachycardia. CONCLUSIONS: Conventional transurethral resection of the prostate can be effectively managed in the day surgery setting with minimal morbidity. There are significant advantages in reduction of catheterization time and duration of hospital stay, and the procedure compares favorably with new modalities.     

Maternal smoking during pregnancy and the risk of conduct disorder in boys

(BACKGROUND): We studied the clinical efficacy of transurethral microwave thermotherapy (TUMT) using Endotherm UMW system (OLYMPUS). (METHODS): TUMT was performed in 28 patients with benign prostatic hyperplasia (BPH). Three patients of them were catheterized because of urinary retention. The treatment was performed in a single session for an hour. The urethral surface temperature was set at 39 degrees C, and the coolant flow of the urethral applicator (21 Fr balloon catheter) was set at 30 ml/min, to heat up the broad area of the prostate up to 45 degrees C. The clinical efficacy was evaluated by analyzing subjective responses, using the International Prostate Symptom Score (I-PSS) scale (S) and QOL score (L), and objective responses, using peak urinary flow rate (Qmax), average flow rate (Qave), residual urine volume and prostate volume following the treatment. (RESULTS): At 24 weeks after the treatment, significant improvement were observed in S score (41%), L score (37%), Qmax (53%) and Qave (62%). Although there was no significant decrease in residual urine and prostate volume. The three patients, with a catheter indwelled because of urinary retention, were all free of the catheter within 4 weeks after the treatment. During and after the treatment, no severe adverse effects, including transient urinary retention needed for indwelling a catheter, was detected. (CONCLUSION): A single session of TUMT by Endotherm UMW considered to be safe and useful for symptomatic BPH patients, even who are not indicated for transurethral resection of the prostate (TUR-P) because of underlying disorders.     

Sexual function following high energy microwave thermotherapy: results of a randomized controlled study comparing transurethral microwave thermotherapy to transurethral prostatic resection

PURPOSE: We evaluate changes in sexual function in patients treated with high energy transurethral microwave thermotherapy compared to transurethral resection of the prostate. MATERIALS AND METHODS: A total of 147 patients randomized to undergo transurethral microwave thermotherapy or transurethral resection of the prostate were asked to complete a self-administered questionnaire evaluating sexual function before, and 3 and 12 months after treatment. The questionnaire dealt with such items as social status, libido, quality of erection, ejaculation and overall satisfaction of sexual functioning. RESULTS: There was a statistically significant improvement of micturition in both groups. The improvement in the transurethral prostatic resection group was significantly better than in the transurethral microwave thermotherapy group. Antegrade ejaculation occurred at 3 months following treatment in 27% of the transurethral prostatic resection group compared to 74% of the transurethral microwave thermotherapy group and at 1 year in 37 and 67%, respectively. Significantly more patients undergoing transurethral prostatic resection (36%) had changes in sexual function compared to the transurethral microwave thermotherapy group (17%). The transurethral microwave thermotherapy group was more satisfied with the sex life. Of these patients 55% graded sex as very satisfying compared to 21% in the transurethral prostatic resection group. The severity of symptoms was not correlated with sexual function in this study. In general, older patients had sexual dysfunction more often, while younger patients had pain during sexual activities more frequently. CONCLUSIONS: Although clinically less effective, high energy transurethral microwave thermotherapy is a better therapeutic option than surgery for patients who want to preserve sexual function. In particular ejaculation is often preserved after transurethral microwave thermotherapy while there is significant deterioration following transurethral prostatic resection. In general, older patients have greater sexual dysfunction.     

Restricted occurrence of an unusual ganglioside GD1 alpha in rat brain and its possible involvement in dendritic growth of cerebellar Purkinje neurons

The type and magnitude of urinary symptoms, the behavioral adjustments necessitated by such symptoms, and the degree of patient satisfaction with treatment and current health were evaluated in 102 men with symptomatic benign prostatic hyperplasia (BPH) who had been receiving finasteride for 9 to 12 months. We also evaluated these variables in a group of 109 men who had undergone transurethral resection of the prostate (TURP) for symptomatic BPH 9 to 12 months before the study. A validated, patient-directed telephone questionnaire was used to solicit information. Men with BPH who continued to receive finasteride therapy for at least 9 months experienced considerable symptomatic relief during the first year of therapy, and reported a high degree of satisfaction with their urinary condition. Urinary symptoms either resolved or occurred only rarely in the majority of men treated with finasteride. Most of the BPH patients taking finasteride (78%) indicated that urinary symptoms did not restrict their participation in normal activities. Fifty-four percent of finasteride patients rated their current health as excellent or very good, and 87% indicated that their current condition represented an improvement over their pretreatment state. Responses in the men treated with TURP reinforced previous observations about the effectiveness of this treatment in men with symptomatic BPH. Thus in the appropriate patient group, finasteride represents an effective management option for symptomatic BPH.     

Role and significance of information tools in occupational asthma]

There is no universally successful therapy for chronic nonbacterial prostatitis. Successful outcomes of treatment have been independently reported with transurethral heat therapy and balloon dilation. The THERP transurethral "hot balloon" uses balloon dilation of the prostatic urethra and radiofrequency heating of the prostate. Patients with refractory chronic nonbacterial prostatitis were assessed with validated prostatitis-specific symptom indices prior to, 3, and 6 months after 900 seconds of THERP treatment. Although early results appeared promising the long-term results in four patients led to early termination of the study. Although one patient did have improvement at 6 months, no patient reported improvement at 9 months, and the adverse events (urinary retention, retrograde ejaculation, hematuria, urethral stricture, worsening of symptoms) of this treatment in prostatitis patients was significant. This study demonstrated no sustainable efficacy and substantial adverse effects for the use of combination balloon dilation and heat therapy for patients with chronic nonbacterial prostatitis.     

Intraprostatic temperature monitoring during transurethral microwave thermotherapy for the treatment of benign prostatic hyperplasia

PURPOSE: We evaluated whether the results of transurethral microwave thermotherapy improve using high intraprostatic temperatures of 55C or greater. MATERIALS AND METHODS: We accrued 30 men 58 to 85 years old (mean age 69) from the waiting list for transurethral prostatic resection in whom maximum urinary flow was less than 13 ml. per second and Madsen score was greater than 8. According to the Abrams-Griffith nomogram all but 1 patient had obstruction. Before treatment 3 thin temperature probes, each containing 5 sensors in a row, were introduced into the prostate from the perineum and positioned using transurethral ultrasound guidance. The microwave power of the transurethral microwave thermotherapy equipment was set based on the actual temperature in the prostatic tissue. A temperature of at least 55C and often more than 60C was reached at the hottest spot. Treatment duration was 1 hour. Postoperatively an indwelling catheter remained in place for 2 weeks. Patients were followed for 6 months with the first followup after 3 months. RESULTS: At the 3-month followup mean maximum urinary flow had increased from 7.4 to 12.5 ml. per second and the mean Madsen score had decreased from 12.6 to 2.9. At the 6-month followup mean maximum urinary flow was 12.2 ml. per second and the mean Madsen score was 3.4. Using pressure-flow data we divided the patients into responders and nonresponders. In the 18 responders maximum urinary flow had increased from 7.2 to 14.6 ml. per second (103%), the Madsen score had decreased from 12.5 to 1.4 (89%) and detrusor pressure had decreased from 9.2 to 6 kPa. (35%). CONCLUSIONS: High energy transurethral microwave thermotherapy relieved bladder outlet obstruction in 60% of the patients and had a good effect on symptoms. Compared with a previous multicenter study with 40% responders, using the same criteria there were 60% responders in our series. Our results indicate that better control of intraprostatic temperature provides better results, approaching those after transurethral prostatic resection.     

Subchronic oral hepatotoxicity of turmeric in mice--histopathological and ultrastructural studies

OBJECTIVE: To analyze the effects of flutamide in patients with physical and/or mental disorders consulting for urinary symptoms secondary to benign prostatic hyperplasia (BPH). METHODS: 50 patients with BPH in whom surgical treatment was contraindicated due to their physical and/or mental condition were treated with flutamide 250 mg/day. Four patients presented with urinary retention and 46 patients had prostatic symptomatology. Patients were evaluated using the symptoms score (I-PSS) and quality of life (QL). Prostate volume was measured by transabdominal US; the maximum flow rate at spontaneous micturition and residual urine were determined. RESULTS: At 12 months, the I-PSS and QL scores decreased by a mean of 7 and 3 points, respectively. The US demonstrated that treatment had reduced prostatic volume by a mean of 10 gms. The maximum flow rate at spontaneous micturition increased 3 ml/sec and residual urine decreased by 15 ml. CONCLUSION: Flutamide is another alternative to surgery in specific patients with BPH.     

Transurethral thermotherapy of the prostate--a very promising treatment method for benign prostatic hyperplasia

Transurethral resection of the prostate remains the most common method for the treatment of benign prostatic hyperplasia (BPH). Due to unsatisfactory results in about 18% of the patients new methods to treat BPH have been developed. We evaluated 45 patients 6 and 12 months after transurethral microwave thermotherapy using the Prostatron device with Prostasoft 2.5 software. There was a significant improvement of the urinary symptoms and of the quality of life index from 18 to 9.5 and from 3.2 to 1.6 points, respectively. Urinary flow rate improved from 8.8 to 12.1 ml/sec and residual urine was reduced from 101 to 52 ml. The treatment was well tolerated and side effects were minimal. High-energy transurethral microwave thermotherapy is an effective and safe minimal invasive alternative to treat BPH in selected patients. As no anesthesia is required transurethral microwave thermotherapy can also be offered to high risk and elderly patients.     

Cholestasis assessment by activity of antioxidant enzymes and composition of plasma lipoproteins in patients with liver diseases]

23 patients with benign prostatic hyperplasia (BPH) aged 60-82 years underwent transurethral resection (TUR) of the prostate in different periods after thermal treatment which had appeared uneffective or brought complications. In the performance of the endoscopic techniques we found macroscopic changes of the prostatic parts of the urethra and bladder cervix characteristic for certain thermal impact (energy, power, site of exposure). Intraoperative bleeding of prostatic tissue was also different depending primarily on the time which had passed after the thermal treatment. Minimal bleeding occurred at least 3 months after the thermotherapy. Thus, thermal treatment of the prostate can be used in combined treatment of BPH for reducing intra- and postoperative hemorrhage due to subsequent TUR. Among the methods of thermal therapy, transurethral microwave thermotherapy is preferable as minimally invasive and deeply penetrating into the depth of the prostatic gland with maximal effect. TUR of the prostate should be performed not earlier than 3 months after thermotherapy which is indicated only for patients at high risk of intraoperative hemorrhage because of unaffected circulation. Therefore, it is desirable to include transrectal dopplerography of the prostate to urological examination of BPH patients.     

A prospective, randomized 1-year clinical trial comparing transurethral needle ablation to transurethral resection of the prostate for the treatment of symptomatic benign prostatic hyperplasia

PURPOSE: We assess the 1-year efficacy and safety of transurethral needle ablation of the prostate compared to transurethral resection of the prostate for the treatment of symptomatic benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: A prospective, randomized clinical trial of 121 men 50 years old or older with symptomatic BPH was performed at 7 medical centers across the United States. Of the men 65 (54%) were treated with transurethral needle ablation of the prostate and 56 (46%) underwent transurethral resection of the prostate. Mean and percentage changes from baseline and between cohorts for American Urological Association (AUA) symptom score, AUA bother score, quality of life score, peak urinary flow rate and post-void residual urine volume were measured at 1, 3, 6 and 12 months following treatment. Length of procedure, hospitalization, type of anesthesia, post-procedure catheterization, side effects and sexual function were compared. RESULTS: Transurethral needle ablation and resection resulted in a statistically significant improvement in AUA symptom, bother and quality of life scores, peak urinary flow rate and post-void residual. At 1-year followup, needle ablation and resection were equally effective in enhancing quality of life. Needle ablation had less effect on sexual function, with resection being associated with a greater incidence of retrograde ejaculation. Needle ablation could be performed as an outpatient procedure with local anesthesia while resection required anesthesia and hospitalization. Needle ablation was associated with markedly fewer side effects than resection. CONCLUSIONS: Compared to transurethral resection of the prostate, transurethral needle ablation of the prostate is an efficacious, minimally invasive treatment for symptomatic BPH that is associated with few side effects.     

Incidence of erectile impotence secondary to transurethral resection of benign prostatic hyperplasia, assessed by preoperative and postoperative Snap Gauge tests

In an attempt to assess the impotence rate secondary to transurethral resection of the prostate more objectively than by merely interviewing patients, potency was evaluated with the Snap-Gauge test. The test was used preoperatively to recruit patients with intact potency. The 98 patients studied underwent transurethral resection of the prostate and were retested during postoperative night 4. Of the 98 patients 64 remained potent while 34 did not. These 34 men were retested 3 months later, and 26 were potent and 8 were impotent. Therefore, 8 of 98 patients (8.3%) became impotent as a consequence of transurethral resection of the prostate. The risk specific to subgroups in cases of small (less than 10 gm. resectable tissue) and larger adenomas is 11.1% and 7.7%, respectively, for men older than 65 years, and 7.1% and 0%, respectively, for men younger than 65 years. A selective indication taking into account patient age and prostatic size might further lower the already low impotence risk of transurethral resection of the prostate.     

Care of the patient undergoing transurethral resection of the prostate

Transurethral resection of the prostate (TURP) for benign prostatic hypertrophy is a common surgical procedure in the United States. Left untreated, benign prostatic hypertrophy can lead to detrimental consequences such as renal failure from urinary obstruction. Although TURP is a common procedure, it is not without risk. Complications can occur, and the perianesthesia nurse must be familiar with them and their treatment. Complications related to the surgical procedure and the anesthesia technique must be assessed and treated quickly to prevent morbidity and mortality in these patients. The perianesthesia nurse is instrumental in managing and preventing complications associated with transurethral resection of the prostate.     

The early postoperative morbidity of transurethral resection of the prostate and of 4 minimally invasive treatment alternatives

PURPOSE: We compared the early postoperative morbidity of transurethral resection of the prostate to minimally invasive treatment alternatives with respect to the objective rate of complications and subjective morbidity assessed by a patient addressed diary-type questionnaire. MATERIALS AND METHODS: Parameters evaluated preoperatively were the International Prostate Symptom Score (I-PSS), free flow study, post-void residual, transrectal ultrasonography and a pressure-flow study. The patients underwent transurethral resection (28), transrectal high intensity focused ultrasound (20), visual laser ablation (15), transurethral needle ablation (15) and transurethral electrosurgical vaporization (17) of the prostate. On the day of hospital discharge the patients received the questionnaire and were asked to answer daily 7 questions concerning micturition status. After 6 weeks the questionnaire was returned and an I-PSS, uroflowmetry and post-void residual were obtained. RESULTS: Preoperatively, there was no statistically significant difference regarding the I-PSS, peak flow rate, prostate volume and degree of bladder outlet obstruction. After 6 weeks the peak flow rate improved most prominently after transurethral electrosurgical vaporization (+ 13.2 ml. per second), transurethral resection of the prostate (+ 12.3 ml. per second) and visual laser ablation (+ 11.1 ml. per second). The I-PSS decreased most significantly after transurethral resection (-14.1) and transurethral electrosurgical vaporization (-8.4). There was no difference regarding the rate of adverse events within the first 6 weeks postoperatively in the 5 treatment arms. Mean duration of catheter drainage plus or minus standard deviation was 3.7 +/- 1.2 days after transurethral resection of the prostate, 6.8 +/- 1.7 days after high intensity focused ultrasound, 7.8 +/- 1.5 days after visual laser ablation, 2.0 +/- 0.4 days after transurethral needle ablation and 3.3 +/- 0.8 days after transurethral electrosurgical vaporization. Analysis of the questionnaire revealed that the daytime frequency, degree of hematuria and incontinence were comparable for all 5 procedures within the first 6 weeks postoperatively. Postoperative dysuria was greatest after visual laser ablation and transurethral electrosurgical vaporization. Regarding the degree of nocturia, there was no improvement after visual laser ablation, while the remaining 4 procedures yielded a significant and comparable decrease. The most significant subjective improvement in uroflowmetry was reported after transurethral resection of the prostate and transurethral electrosurgical vaporization. Regarding the global quality of life question, the patients were generally more worried after visual laser ablation and transurethral needle ablation compared to the other 3 procedures. CONCLUSIONS: The overall morbidity of transurethral resection of the prostate within the first 6 weeks postoperatively is equivalent to that of the 4 minimally invasive treatment alternatives evaluated in our study. When comparing the 4 minimally invasive procedures, no dramatic differences were notable, although visual laser ablation seems to be associated with a greater degree of morbidity as assessed by this questionnaire.     

Failure to void after transurethral resection of the prostate and mode of presentation

OBJECTIVES: Contemporary audits and reviews of outcome after transurethral resection of the prostate (TURP) make little reference to failure to void following catheter removal after this operation. There have been few reports of the likelihood of a successful trial without a catheter after TURP related to mode of presentation. We report the results of a retrospective review of outcome of TURP related to mode of presentation, age, and prostate histologic findings in a consecutive series of patients in a London Teaching Hospital. METHODS: A consecutive series of 379 patients (381 TURPs) was reviewed to document the incidence of and risk factors for failure to void following initial trial without a catheter after TURP. RESULTS: Twelve percent of men failed to void after TURP on the initial trial without a catheter. In those patients presenting with lower urinary tract symptoms, there were no instances of failure to void. Ten percent of patients with acute retention (painful inability to void, urine volume less than 800 mL), 38% with chronic retention (maintenance of spontaneous voiding, bladder volume greater than 500 mL), and 44% with acute on chronic retention (painful retention, urine volume greater than 800 mL) failed to void after TURP. Only 1% of patients required management by long-term catheterization. Failure to void on catheter removal was not related to age or prostate histologic findings. CONCLUSIONS: Bladder volume at initial presentation in patients with urinary retention provides important information about the likelihood of re-establishing spontaneous voiding catheter removal following TURP. Patients should be warned that there is a significant chance of failure to void after TURP, the exact risk depending on their mode of presentation, but that most will ultimately not require a permanent indwelling catheter.     

Reconstruction of anterior cruciate ligament using the doubled tendon graft technique: an experimental study in rabbits

BACKGROUND: Mepartricin, a semisynthetic polyene derivative with a favorable effect on urethro-prostatic function, was clinically evaluated, adopting the diagnostic and research criteria recommended by the First International Consultation on BPH. METHODS: A multicenter, randomized, double-blind, parallel-group study compared mepartricin 40 mg/daily to placebo in the treatment of 196 patients with newly diagnosed BPH and mild-to-moderate symptomatology. International Prostate Symptom Score (I-PSS), quality of life (QoL) index and maximum urinary flow-rate (Qmax) were determined every 4 weeks for 6 months; postvoiding volume, prostate volume, and prostate-specific antigen (PSA) were assessed after 3 and 6 months of therapy. RESULTS: Mepartricin was shown to determine a statistically significant improvement over placebo in I-PSS and QoL index from month 2 onwards, and a significant linear increase in Qmax over the study period. At month 6, the improvement in the mepartricin and placebo groups in I-PSS, QoL index, and Qmax was 6.3 (standard error (SE) 0.51) and 4.2 (SE 0.60) points (P = 0.003), 0.99 (SE 0.14) and 0.62 (SE 0.12) points (P = 0.036), and 2.7 (SE 0.46) and 1.2 (SE 0.46) ml/sec (P = 0.051), respectively. No significant differences were noted in postvoiding residual volume, prostate volume, or PSA. Mepartricin tolerability was good, showing no adverse events on sexual function. CONCLUSIONS: Mepartricin proved to be an effective treatment of benign prostatic hyperplasia, determining an improvement in symptoms, quality of life, and peak urinary flow.     

An open study on the efficacy and safety of transurethral needle ablation of the prostate in treating symptomatic benign prostatic hyperplasia: the University of Florida experience

PURPOSE: We determine the safety and efficacy of transurethral needle ablation of the prostate in patients with moderate to severe symptoms of benign prostatic hyperplasia. MATERIALS AND METHODS: Transurethral needle ablation of the prostate was performed on 45 consecutive patients. For an average prostate of 2.5 to 3 cm. long treatments were performed in 2 separate planes at 4 quadrants (2, 4, 8 and 10 o'clock positions) each. The 2 planes were 1 cm. below the bladder neck and 1 cm. proximal to the verumontanum. For prostatic urethral lengths longer than 3 cm. a treatment plane was added for each additional centimeter of prostatic urethra. The procedure was performed in 26 patients under local anesthesia using 20 cc 2% intraurethral lidocaine gel (11) or supplemented with intravenous 1.25 to 5 mg. midozolam (15). Of these patients 2 had a supplemental perineal block using a mixture of equal amounts of 15 cc 2% lidocaine without epinephrine and 0.25% bripivacaine, 10 underwent the procedure under general anesthesia, 2 had epidural and 4 had spinal anesthesia, and 3 had managed anesthesia care. Mean length of each procedure was 79 minutes (range 50 to 240). All procedures were done on an outpatient basis and patients were released on the same operative day. RESULTS: Mean prostatic volume on transrectal ultrasound was estimated at 48.1 cc (range 20 to 185). Following treatment the International Prostate Symptom Score decreased from a mean of 20.9 at baseline to 15.4 at 1 month, 16.1 at 3 months, 10.7 at 6 months and 9.9 at 1 year. The peak flow rate improved from a baseline mean of 8.3 to 13.4 at 3 months, 13.1 at 6 months and 14.9 at 1 year. The quality of life score improved from a baseline of 4.8 to 3.5, 2.2, 2.5 and 1.03 at 1, 3, 6 and 12 months, respectively. Of the 2 patients in whom the procedure failed; 1 required a bladder neck incision at 3 months and the other transurethral resection of the prostate. Foley catheters were left in place in all patients for an average of 4.85 days. CONCLUSIONS: After a followup of up to 12 months we conclude that transurethral needle ablation of the prostate is an effective treatment for symptomatic benign prostatic hyperplasia. This procedure has minimal morbidity, is less costly than conventional transurethral resection of the prostate and can be performed as an outpatient office procedure under local anesthesia in a significant number of patients.     

Outcome of transurethral prostatectomy in men over 80 years

Two-hundred-and-twenty-nine men aged between 80 and 97 years (mean 83 years) underwent transurethral prostatectomy (TUR-P) for lower urinary tract symptoms (LUTS). All case records were reviewed. The follow-up period was 6-16 years. One-hundred-and-seven patients underwent operation because of acute urinary retention, and 122 because of chronic retention. The mean weight of tissue removed was 20 g (1-200 g). The perioperative mortality (< 1 month) was 2% (5 patients). Postoperative complications occurred in 21% (49 patients). Reoperation was performed in 11% (26 cases). The result was considered satisfactory in 196 patients (86%). The present data demonstrate that transurethral resection of the prostate in men over 80 years has a good outcome with an acceptable urological complication rate and mortality, and we therefore advocate surgery instead of watchful waiting in the fit patient.
