Sexual function following retropubic TVT and transobturator Monarc sling in women with intrinsic sphincter deficiency: a multicentre prospective study

Introduction and hypothesis A prospective study comparing the effect of the tension-free vaginal tape (TVT) to the Monarc sling on sexual function in women with urodynamic stress incontinence (USI) and intrinsic sphincter deficiency (ISD) is presented. Methods Eighty-seven sexually active women with USI and ISD were enrolled. Sexual function was assessed pre-operatively and at 6 and 12 months post-operatively by history, PISQ-12, UDI-6 and IIQ-7 questionnaires. Results A significant increase was detected in PISQ-12 score following both TVT and Monarc insertion. This score was greater in the TVT group at 6 months but not at 12 months when compared to the Monarc group. A significant decrease in UDI-6 and IIQ-7 score was detected. Specifically, coital incontinence and fear of leakage were reduced in both groups, and no change in dyspareunia or orgasm intensity was found. Conclusions Sexual function improves 6 months after TVT or Monarc sling, and this benefit is maintained at 12 months.
