Lumboscopic renal biopsy (author's transl)

Renal biopsies with a new "lumboscopic" (half-open) technique were performed in 109 patients. Access to the kidney was gained by a small flank incision and biopsies from the renal cortex were taken under vision through the lumboscope. The biopsies were successful in all cases. The advantages of the new technique are convincing and lumboscopy suited to replace the regular open biopsy procedure.     

Intrauterine renal vein thrombosis (author's transl)

One case of renal venous thrombosis in a male foetus, born of a diabetic mother is reported. The intrauterine origin and the long age of the thrombosis were confirmed by pathologic studies. Some speculation about the etiopathogenic mechanisms of intrauterine renal venous thrombosis are made.     

Radiation therapy in renal adenocarcinoma (author's transl)

Sole irradiation treatment for renal carcinoma or its metastases has to be regarded as only a palliative therapy, whereas postoperative radiation therapy brings about a distinct diminution of the frequency of local recurrences, and, at least in advanced tumor stages, an improvement of the 5-year survival rate. Long-term preirradiation (ca 3000 rd TD within 3 weeks, and operation after another three weeks) or short-term pre-irradiation (ca 1200 to 2000 rd TD within 2 or 4 days, and operation the next day) are tolerated well and do involve no disturbances of the wound healing. Surgical treatment is not complicated by short-term irradiation, but often is easier following long-term irradiation; beyond this, the latter may just render possible a radical extirpation of the renal tumor. It appears from first results that decrease of distant spread and improvement of recovery rates in advanced tumor stages may be within reach, particularly in connection with post-operative irradiation.     

Problems of infections following renal transplantation (author's transl)

Infections arising as a complication of immunosuppressive therapy were analyzed in more than 40 renal transplant patients. Bacterial infections were observed in 78.0%, viral in 68.3% and mycotic infections in 56.3% of cases seen during a 3-year investigation. Infection was the cause of death in 5 out of 8 cases with fatal complications. Bacterial infections of the lungs were amongst the gravest post-transplant complications. Hepatitis B, herpes simplex and cytomegalovirus were the most common viral infections. Simultaneous bacterial, viral and Candida albicans infections--so-called "triple infections"--with a very poor prognosis were diagnosed in 25% of the investigated cases. The data show that after cadaveric kidney transplantation special emphasis should be laid on careful prophylaxis of infections and diagnostic measures for the early recognition of possible infections arising as a complication of immunosuppressive therapy.     

Plasma hydroxyproline in chronic renal failure (author's transl)

The plasma concentration of hydroxyproline fractions were determined in 50 adult patients with renal insufficiency and 19 patients receiving maintenance hemodialysis treatment. Free and peptide bound hydroxyproline fractions (total hydroxyproline) were elevated, the protein bound hydroxyproline (hypro-protein) was only slightly increased without significant correlation to the degree of renal insufficiency. The total hydroxyproline correlated only with the level of the alkaline phosphatase. The validity of the single fractions of hydroxyproline in plasma as parameter of the renal osteodystrophy is discussed.     

The echotomographic diagnosis of renal expansive processes (author's transl)

The authors carried out a study of renal echotomography as a diagnostic technique for renal expansive processes. The reliability of the results obtained, the simple technique, its absolute harmlessness and the low cost are tending to give echotomography an increasingly important place in the differential diagnosis of renal masses. This limits, without eliminating, the indications for arteriography and exploratory surgery. It should in no way be considered to be in competition with radiography, but rather as an excellent complementary technique. By the use of apparatuses giving moving images, our group obtained 96.4 per cent of success in liquid masses and 90.3 per cent of success in solid masses.     

Dumping-prophylaxis (author's transl)

The dumping syndrome is due to a vigorous reflex distension of the jejunum, caused by the stomach violently evacuating its contents. The aim of treatment is to overcome the drastic evacuation by restoring the rhythmic peristalsis of the stomach (eukinetics). This can be achieved by a special diet. Every meal should begin with well chewed solids (pulp) and avoid all fluids. With a well organised medical staff a complete success can be achieved. Surgical measures in Dumping can be avoided.     

Paediatric management of acute and chronic renal insufficiency (author's transl)

Acute or chronic renal insufficiency in children is not so rare. Causes are prerenal, renal or postrenal disturbances of kidney function. The dysregulation of the homoeostatic balance of the intra- and extracellular fluid composition presents a picture of a life-threatening illness. By dietetic and medicamental correction of the disturbances uremic complications can be prevented. This conservative treatment is presented.     

Diagnosis and treatment of renal traumas in childhood (author's transl)

The diagnosis of a kidney trauma is discussed and the great importance of angiography besides i. v. urography and retrograde pyelogram is pointed out. In surgical treatment exact urinary diversion and wound drainage are most important points to avoid later complications.
