Objective To explore the clinical characteristics of patients with female stress urinary incontinence(SUI) and efficacy of Transobturator Tension-free vaginal tape procedure. Methods We retrospectively analyzed the clinical data of 319 cases who were operated transobturator tension free vaginal tape in Shanghai Changhai Hospital Affiliated of Naval Medical University from Oct.2009 to Jun.2018. Patients age ranged from 39 to 91 years old, with the average age of(59.2±9.7)years old. 145(45.5%) patients aged ≥60 years old. Among them, 155 (48.6%) patients with moderate SUI, 164(51.4%) with severe SUI.96 cases(30.1%) hypertension, 24(7.5%)diabetes, 2(0.6%)had not given birth, 317(99.4%)patients had given birth more than once. 31(9.7%) coexisting pelvic organ prolapse with POP-Q stage 2 and above. Maximum urinary flow rate ranged 5.2-72.6 ml/s. Cystometric capacity ranged 56.7-1 013.6 ml. Average preoperative ICIQ-SF score was 13.9 (range 9-19). Results Operative time of 288 TVT-O procedures ranged 19-60 min, and 31 cases in the surgical management of cystocele with concomitant ranged 50-120 min. A total of 265 patients were evaluable followed up for 12-24 months, Objective cure rate and subjective cure rate were achieved in 95.8%(254 cases) and 93.6%(248 cases) respectively. POP was cured in 96.8% patients.Postoperative complications were 10.6% groin pain, 4.5% urgency, others including urinary tract infection(3.4%), de novo dysuresia(2.6%), dyspareunia(1.1%), and one case of bladder injury, one case sling erosion and one case scar hyperplasia. Conclusions Female stress urinary incontinence were mainly in middle-aged and elderly people who had severely psychological quality of life lasting for several years. TVT-O may achieve a high success or improvement rate and no serious adverse effects. One operation could correct the stress urinary incontinence and simultaneously correct prolapse.
