Urinary incontinence after treatment for localized prostate cancer.
The incidence of incontinence after radical prostatectomy has ranged from 0 to 57% depending on the series and the type of incontinence considered. When total incontinence (not minimal stress incontinence) is reported, the average incidence is no more than 5%. This figure will increase with age, and in most series, approximately 10% of patients around the age of 70 will have total incontinence postoperatively. Preservation of continence after radical prostatectomy depends largely on the preservation of the distal urethral smooth-muscle sphincteric mechanism, which begins at the pelvic floor and ends at the prostatourethral junction. Newer techniques that attempt to increase postoperative continence include not cutting the puboprostatic ligaments and attempting to preserve as much striated muscle as possible along the length of the remaining urethra. Patients who are incontinent for 6 months after the surgery with no evidence of improvement will probably not become continent on their own. Therefore, some type of therapy should be considered. The options are periurethral injection of a bulking agent, implantation of an artificial sphincter, and, most recently, a bulbourethral sling procedure.
