Objectives: To discuss the clinical features of stress urinary incontinence (SUI) in Chinese females and to compare the efficacy of tension free-vaginal tape (TVT) and Marshall-Marchetti-Krantz (MMK) procedure in treatment of SUI.
Patients and methods: A total of 228 patients with SUI who underwent surgical repair in our institute from January 1998 to May 2008 were enrolled in this study. Preoperative variables were reviewed,including age, parity, history and severity of incontinence, previous pelvic surgery, and menopausal status. Urodynamic examinations were performed before operation. Operative time, blood loss, complications, and hospital stay were reviewed. Chi-square test was used, and P < 0.01 was considered statistically significant.
Results: All patients had parity ranged from 2 to 5 times, average 2.8±1.7. Of the 228 cases, 24 (10.53%) had history of dystocia, 12 (5.26%) had previous pelvic surgery, and 12 (5.26%) combined with mild to moderate uterine prolapse. The differences in operative time (30.6±10.3 minutes versus 94.6±20.7 minutes), blood loss (14.2±11.8 ml versus 183.1±30.6 ml), and hospital stay (5.9±0.6 days versus 8.3±1.2 days), between TVT and MMK were statistically significant. The cure rate of MMK procedure was 80.2%, 88.1%, and 89.5% in 3, 6, and 12 months after operation, which was 90.0%, 89.7%, and 90.0% in TVT group respectively.
Conclusions:
More parity and previous pelvic surgery were the risk factor of SUI in Chinese women. The cure rate of MMK procedure was increased and then stabilized in 6 months after surgery. TVT and MMK procedure were equally efficient in treating SUI, but patients experienced shorter operation time, less blood loss and hospital stay in TVT procedure.
