[Renal insufficiency caused by prostatic cancer. Apropos of 7 cases].

Prostatic carcinoma was discovered in seven patients presenting with renal failure, with ages ranging from 44 to 84. Management consisted of various associations of estrogens, steroids, hemodialysis, TUR, ureteral implantation, or ureteral prostheses. Cutaneous ureterostomy was avoided whenever possible. Survival was less than one year for four patients with anaplastic carcinoma, while all the others survived for at least four years. Two different obstructive mechanisms caused the acute renal failure in these patients: simple infravesical obstruction, easily relieved by TUR, and retroperitoneal ureteral obstruction, requiring a more complex operative procedure in hormone dependent patients.
