Abstract: Objective To assay the time-variations and relating factors of Stress Urinary Incontinence (SUI) after radical prostatectomy. Methods During Mar.2010 to Nov.2013, 91 cases of laparoscopic radical prostatectomy were performed by a single surgeon, followed-up over 1 year. Basic information of all cases: the age range was 51～75 years, 67 on average; PSA range before surgery was 0.1～50.8 μg/L, 10.3 μg/L on median; the Gleason score was 6～8; and TNM stage range T1c～T2c. The catheter removal undertook 2 weeks after operation, then analyzed the incontinence rate and development pattern of incontinence after surgery. Urinary continence defined as 3 below conditions: urine leakage free, little leakage without urinal pads or less than 1 pad per day. Results the follow-up visit range 1～45 months, 18 on average. In line with the 3 definitions, urinary continence rate after catheter removal were: 0％, 5％ and 33％; 30％, 63％ and 93％ by 3 months after surgery; 76％, 98％ and 100％ by 12 months after surgery. Conclusion the SUI after laparoscopic radical prostatectomy is a common, however, the majority of which can improve within 3～6 months after surgery, and reach basic control within 1 year.
