Preoperative risk factors for early postoperative urinary continence recovery after non-nerve-sparing radical prostatectomy in Chinese patients: a single institute retrospective analysis.

Urinary incontinence (UI) remained a significant complication after radical prostatectomy and led to impaired quality of life. Early continence is a goal to take into consideration for better patient satisfaction after radical prostatectomy. To identify the independent preoperative risk factors associated with UI after radical prostatectomy (RP), we evaluated 446 patients treated with non-nerve-sparing RP between 2010 and 2013 at our institution. The incontinence rate was 98.7% and 46.6% after catheter removal and 3 months after surgery, respectively. We examined several preoperative factors including age, smoking, body mass index (BMI), comorbidities such as hypertension and diabetes, preoperative prostate-specific antigen (PSA) level, Gleason score, and preoperative pelvic floor muscle exercise (PFME). The results suggested preoperative PFME was the only independent protective risk factor for immediate continence after catheter removal. At 3 month following surgery, age at surgery represented a risk factor for delayed continence, while BMI and preoperative PFME were the protective risk factors for postoperative UI. Our results supported that age and preoperative PFME were predictive factors for early continence after RP. These findings could help clinicians to counsel men and their partners about postoperative incontinence.
