    Abstract:
    PURPOSE: We present outcome and quality of life analyses for the treatment of post-radical prostatectomy bladder neck contracture with urethral wall stent insertion and subsequent artificial urinary sphincter placement. MATERIALS AND METHODS: A retrospective analysis from June 2001 to September 2007 identified 25 consecutive men who underwent urethral wall stent placement for severe, recurrent bladder neck contracture despite aggressive transurethral resection after radical prostatectomy. Assessment of symptoms and quality of life impact from urinary incontinence was conducted with a self-administered, standardized questionnaire. Nonparametric testing was used for comparing covariates among groups. Univariate Cox proportional hazards modeling was used to assess predictors of treatment failure. P values are double-sided and are considered statistically significant if </=0.05. RESULTS: Etiology of recurrent bladder neck contracture was radical prostatectomy in all patients. Concurrent severe stress incontinence before treatment of bladder neck contracture was noted in 23 of 25 patients (92%). Before urethral wall stent insertion a median of 3 (IQR 2 to 5) failed endoscopic treatments were performed. Bladder neck contracture stabilization with insertion of 1 urethral wall stent was noted in 13 of 25 (52%) patients with a median followup of 2.9 years from last urethral wall stent insertion. Multiple urethral wall stent insertions (range 2 to 4) salvaged an additional 6 of 25 (24%) patients and failure to obtain patency was observed in 6 of 25 (24%). All patients responded to the questionnaire and quality of life improvement was noted in 23 of 25 patients (92%). CONCLUSIONS: Urethral wall stent and delayed artificial urinary sphincter placement for treatment of severe, recurrent bladder neck contracture and incontinence after radical prostatectomy is associated with improvement in quality of life. Long-term followup is required to further delineate the efficacy of this treatment approach.
