Radical cystectomy with orthotopic neobladder reconstruction following prior radical prostatectomy.

PURPOSE: To review the perioperative and follow-up outcomes of patients undergoing radical cystectomy with orthotopic neobladder reconstruction for bladder cancer after prior radical prostatectomy (RP) for prostate cancer.
METHODS: A retrospective review of more than 1,900 patients treated with radical cystectomy at USC between 1990 and 2011 was conducted. Fifty-six patients were identified who were previously treated with RP for prostate cancer. Twenty-four of these patients (43 %) underwent orthotopic neobladder reconstruction. Perioperative data and follow-up including postoperative continence were analyzed.
RESULTS: The median age at cystectomy for these 24 patients was 68 years (range 55-89). The types of neobladder reconstruction were Kock neobladder in 3, Sigmoid reservoir in 1, Studer neobladder in 12, and T-pouch ileal neobladder in 8 patients. There were no major intraoperative complications. Of 19 patients eligible for evaluation of post-cystectomy urinary control, 11 patients (57.9 %) with good continence (0-1 pad/day) after RP regained preoperative level of urinary control after cystectomy within 1 year. The continence rate of 13 post-RP patients with good continence was 84.6 %. Among the 4 patients who received adjuvant radiotherapy after RP, 1 regained good continence. One with poor continence after prostatectomy had an artificial urethral sphincter (AUS) placed 2 months after cystectomy, and 2 with fair and poor continence after prostatectomy had an AUS placed at the time of cystectomy.
CONCLUSIONS: Patients undergoing radical cystectomy after prior RP pose a challenge to urologists. Those who are continent post-RP have a fair chance of regaining good urinary control with neobladder reconstruction. Adjuvant radiotherapy for prostate cancer may have a negative impact on continence with neobladder reconstruction.
