Sexual function following surgery for urodynamic stress incontinence

The objective of this study was to compare sexual function in women before and after surgery for urodynamic stress incontinence in the absence of pelvic organ prolapse. This was a prospective questionnaire survey. Fifty-four women undergoing surgery (tension-free vaginal tape/tension-free vaginal tape-obturator) for urodynamic stress incontinence with no evidence of detrusor overactivity or concomitant prolapse were assessed preoperatively and 6 months post operatively. Assessment was based on the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ), the International Consultation on Incontinence Questionnaire (ICIQ) and the Patient Global Impression of Improvement. Paired t-tests were used for comparing pre- and post-op scores and unpaired t-tests for comparing observations between groups. Spearman's rank correlation was used for testing whether two numerically scored items were related, and McNemar test was used to compare pre- and postoperative responses to individual questions. ICIQ scores showed significant improvement after surgery (p < 0.001). Women completing PISQ were significantly younger (mean = 54) than those who did not (mean = 65; p < 0.001). The total PISQ score was better postoperatively (preoperative = 87.2, postoperative = 92.7; p < 0.001), with improvements in both the physical (preoperative = 31.0, postoperative = 35.2; p < 0.001) and partner-related domains (preoperative = 18.8, postoperative = 19.9; p = 0.002) but no improvement in behaviour emotive domains (preoperative = 37.3, postoperative = 37.6; p = 0.70). There was a reduction in episodes of coital incontinence postoperatively (preoperatively = 16/54, postoperatively = 39/54; p < 0.002). Previous vaginal surgery, oestrogen status of respondents and hysterectomy status did not affect the PISQ. Surgical correction of stress incontinence is associated with an improvement in sexual function.
