Effectiveness of Retropubic Tension-Free Vaginal Tape and Transobturator Inside-Out Tape Procedures in Women With Overactive Bladder and Stress Urinary Incontinence

초록

Purpose: We compared the effectiveness of the retropubic tension-free vaginal tape (TVT) and the transobturator inside-out tape (TVT-O) in treating symptoms of overactive bladder (OAB) in women with stress urinary incontinence (SUI). Methods: Women with urodynamic SUI and OAB (mean urgency episodes >= 1 and frequency >= 8/24 hours on a 3-day voiding diary) were assigned to the TVT or TVT-O group. Preoperative measures were based on a urodynamic study, 3-day voiding diary, the Bristol Female Lower Urinary Tract Symptoms questionnaire (BFLUTSSF), and the urgency perception scale (UPS). At 12 postoperative months, the 3-day voiding diary, symptoms questionnaire, patient satisfaction, and standing stress test were assessed. The primary endpoint was change in the number of urgency episodes/24 hours from baseline to 12 months. Results: In this group of 132 women, 42 received TVT and 90 received TVT-O. The mean urgency episodes/24 hours decreased from 6.3 +/- 5.5 to 1.6 +/- 3.2 in the TVT group and from 5.1 +/- 4.4 to 1.8 +/- 3.0 in the TVT-O group. The mean percent change was significantly greater after TVT than after TVT-O (73% vs. 60%, P = 0.049). All subscales of BFLUTSSF and UPS were significantly improved using either method, with significantly greater improvement seen in the quality of life (QoL) domain after TVT (P = 0.002). There were no significant differences in the cure and satisfaction rates between the two groups. Conclusions: Intervention with the TVT or the TVT-O significantly improved symptoms of OAB in women with SUI and OAB. Urgency and QoL significantly improved after TVT compared with that after TVT-O.
