Evaluation of sexual function and quality of life in women treated for stress urinary incontinence. Tension-free transobturator suburethral tape versus single-incision sling

OBJECTIVE: The aim of this study is to investigate the change in quality of life (QoL) and sexual function in women treated for pure stress urinary incontinence (SUI) using tension-free transobturator suburethral tape (TVT-O) and single-incision sling (SIS) procedures. MATERIALS AND METHODS: From December 2013 to January 2015, a total of 48 female patients with pure SUI and normotonic urethra were consecutively enrolled and randomized into two treatment groups: TVT-O versus SIS. Both groups were homogeneous in the preoperative evaluation of age, body mass index, comorbidities, and pregnancies. Exclusion criteria included urge urinary incontinence, neurogenic bladder, previous surgery for incontinence, and mental or neurological disorders. The female sexual function and QoL were assessed preoperatively and postoperatively (3-12 months follow-up), using the Female Sexual Function Index (FSFI) and the International Consultation on Incontinence Questionnaire. RESULTS: A total of 42 patients completed both the questionnaires (21 patients in the TVT-O group and 21 patients in the SIS group, whereas 6 patients were lost to follow-up). Of the 19/21 (90.4%) of patients who successfully underwent the SIS procedure, 17 (80.9%) reported a complete resolution of SUI, whereas 2 (9.5%) reported an improvement in urinary incontinence at follow-up. In the TVT-O group, 18/21 (85.7%) of patients reported complete recovery, whereas 4.1% patients reported an improvement in the incontinence. The FSFI score increased significantly in both the SIS groups (from 23:51 ± 3.78 to 27.42 ± 3.34; p < 0.001) and TVT-O group (from 23.96 ± 5:56 to 28.09 ± 3.62) with no statistically significant differences between the two treatment groups. CONCLUSION: In our study, both slings showed a high rate of continence without any major complications. The sexual function also improved sharply in all the six FSFI domains, with no statistically significant difference between the two treatment groups.
