To evaluate the factors affecting post operative st ress-related urinary incontinence (POSUI), as well as the treatment and prevention of POSUI. F our hundred and eighty-nine patients were retrospectively reviewed between February 1, 2 007 and December 31, 2009 who were with grade 2 or greater uterine and/or vaginal vaul t prolapse without urinary incontinence. Patients merely with pelvic organ prolapse (POP) we r performed surgical repair, and concomitant surgical corrections of patients with occult incontinence were performed by modified TVT-O procedure. Age, vaginal parity, body mas index, menopausal statusand operation methods were recorded. After a follow-up of one year, lower incidence of POSUI occurred in patients underwent TVT-O procedure together with surgical repair than those merely underwent surgical repair (OR=0.58, p=0.000). It is worthwhile to identify whether patients have occult incontinence before operation. Performing TVT-O procedure together with surgical repair of POP proves to be effective to prevent POSUI.
