    Abstract:
    OBJECTIVE: There are many causative factors for the occurrence of post-prostatectomy incontinence. Objective clinical characteristics, surgical techniques and pelvic floor muscle therapy are the most important ones. The present study was to identify the risk factors associated with urinary incontinence after radical retropubic prostatectomy (RRP). METHODS: A total of 263 patients were recruited for this multivariate analysis. After a close follow-up, a series of pre-, peri- and post-operative factors were recorded and analyzed. RESULTS: Urinary continence after radical prostatectomy was 14.8% at 4 weeks and 94.7% at 16 weeks. The most important recovery interval for urinary continence was 4 - 16 weeks post-operation. Multivariate analysis revealed that age (P = 0.015), blood transfusion (P = 0.017), previous TURP (transurethral resection of the prostate) (P = 0.006) and neoadjuvant hormonal therapy (P = 0.005) were the important risk factors for urinary incontinence. CONCLUSION: During RRP, optimized preservation of urethral rhabdosphincter length, nerve sparing and early postoperative functional exercises can improve the recovery of urinary continence. Age, blood transfusion and previous TURP are the independent prognostic factors. Neoadjuvant hormonal therapy may improve urinary continence through increasing the preoperative length of membranous urethra.
