To evaluate the factors affecting post operative stress-related urinary incontinence (POSUI), as well as the treatment and prevention of POSUI. Four hundred and eighty-nine patients were retrospectively reviewed between February 1, 2007 and December 31, 2009 who were with grade 2 or greater uterine and/or vaginal vault prolapse without urinary incontinence. Patients merely with pelvic organ prolapse (POP) were performed surgical repair, and concomitant surgical corrections of patients with occult incontinence were performed by modified TVT-O procedure. Age, vaginal parity, body mass 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.
