Comparison of the treatment outcome of pubovaginal sling, tension-free vaginal tape, and transobturator tape for stress urinary incontinence with intrinsic sphincter deficiency

Abstract

OBJECTIVE: The aim of this study was to compare the treatment outcome of 3 sling procedures for stress urinary incontinence with intrinsic sphincter deficiency. STUDY DESIGN: This retrospective study included 253 patients who underwent incontinence surgery (pubovaginal sling [PVS] = 87, tension-free vaginal tape [TVT] = 94, and transobturator tape [TOT] = 72) for urodynamic stress incontinence with intrinsic sphincter deficiency. Analysis of variance, chi(2) test, Fisher's exact test, Kaplan-Meier survival analysis, and Cox proportional hazard regression were used for statistical analysis. RESULTS: Overall complication rates were not significantly different. At 2 years postoperatively, the cumulative cure rates of the PVS, TVT, and TOT groups were significantly different (87.25%, 86.94%, and 34.89%, respectively; P < .0001). The risk of treatment failure in women who received TOT was 4.6 times higher than in women who underwent PVS. The 7-year cumulative cure rates of PVS and TVT groups were 59.10% and 55.09%, respectively. CONCLUSION: PVS and TVT were more efficacious, but the long-term cure rates were low
