An unusual presentation of intrinsic ureteral obstruction secondary to carcinoma of the prostate: a case report.
We report on a patient with a known diagnosis of adenocarcinoma of the prostate who had acute renal failure. An excretory urogram showed bilateral ureteral obstruction and retrograde ureteral catheterization was attempted. Because the retrograde catheters could not be passed into the bladder percutaneous nephrostomies were placed immediately. Dissection of the right ureter showed complete intrinsic occlusion by a multinodular tumor, with no evidence of secondary extension at the ureterovesical junction on the right side or circumferential spread along the involved ureter.
