[Tumors of the urethra]

For a period of 6 years 416 men with bladder tumors have been treated by transurethral resections and hemotherapy. The bladder disease was associated with tumors of the urethra: 15.6 per located in its prostate portion and 3.1 per cent in the cavernous part. The urethral tumors were also treated by transurethral resections, ureterotomy and total cystectomy. It was shown that the numerous transurethral resections of bladder tumors contribute to the appearance of urethral tumors: 79 per cent of these developed after the 5. transurethral resection. The results of this study led to a number of inferences: Tumors in the cavernous portion of the male urethra appeared at a relatively younger age (mean 57.8 years); the membranous portion of the urethra is a particular borderline in the histologic structure and the prognosis; appearance of tumors in the cavernous part of the urethra is a poor prognostic sign--tumors in this zone may run a fulminant course with rapid lethal outcome. Inferences were drawn on the methods of choice of treatment of combined bladder tumors and tumors in the cavernous portion of the urethra.
