title: Urethral remnant tumors following simultaneous partial urethrectomy and cystectomy for bladder carcinoma.
abstract: Partial urethrectomy (at least to the bulbous portion) was performed simultaneously in 128 consecutive male patients undergoing radical cystectomy for bladder cancer. Transitional cell carcinoma developed subsequently in the distal urethral remnant in 5 patients (4.0%) followed for 2.6 to 5.7 years (mean 4.1 years) postoperatively. These 5 patients originally had nonpapillary, multifocal and histologically high grade (5) and low stage (4) bladder cancer, 4 with associated carcinoma in situ. Our results suggest that simultaneous total urethrectomy should be considered strongly for patients with high grade nonpapillary multifocal bladder cancer associated with carcinoma in situ. Furthermore, the pattern of distal urethral recurrence in our patients may provide information regarding the appropriate management of the male urethra in potential candidates for continent urinary diversion.
