The frequency of surgery of benign prostatic hypertrophy

OBJECTIVES: To calculate the incidence of surgical treatment of benign prostatic hyperplasia (BPH) in two French departments, Indre-et-Loire and C her, in order to deduce the incidence in France. METHODS: All patients operated for BPH by transurethral resection or transvesical prostatectomy were counted prospectively over a 6-month period by all surgeons of the Indre-et-Loire and Cher departments. Collection of case files was complete and based on BPH resection specimens sent to pathology. 506 patients were included in this survey. RESULTS: The mean age of the patients was 71.8 years. 78% of patients were operated by a private urologist, and 93% by a specialist urologist. The mean postoperative stay was 7.1 days and varied according to the patient's age, the weight of the prostate and the site of the operation (university hospital, private establishment and general hospital). This study allowed calculation of the annual incidence of surgery for BPH in these 2 departments: 822/100,000 men over the age of 50 years. The maximal incidence was observed during the 7th decade of life: 1,742/100,000. In our study, private urologists operated 76 patients for BPH per year. CONCLUSION: Extrapolation of these results to the French population indicates an annual incidence of surgery for benign prostatic hyperplasia in France of 776/100,000 men over the age of 50 years. On the basis of this incidence, an estimated 55,000 to 65,000 men are operated for BPH per year in France.
