The purpose of this study was to prospectively assess the impact of a TVT insertion for the treatment of stress urinary incontinence (SUI) on coital incontinence and overall sexual life. Sexually active women with pure SUI and without concomitant pelvic organ prolapse scheduled for TVT procedure completed a sexual function questionnaire at baseline and 6 months after surgery. Fifty-three patients were enrolled. Preoperatively 23 (43.4%) women experienced urine leakage during intercourse, 21 (91%) during penetration and 2 (9%) on orgasm. The objective cure rate for SUI was 98%. Coital incontinence was cured in 20 of 23 patients (87%). Thirty-three (62.2%) women reported no change in sexual function after surgery and 18 (34%) reported an improvement. Of the latter, 17 (94%) were of those cured from coital incontinence. No significant difference in the incidence of dyspareunia was found postoperatively. Two patients (3.8%) reported intercourse to be worse following surgery, one because of a vaginal erosion and one cited de novo anorgasmia as the main reason.
