About
There are no prospective, randomized studies addressing vaginal penetration restrictions following mid-urethral slings. There is a single cohort study examining expedited recovery following vaginal prolapse repair which advised 3-weeks of vaginal penetration restrictions. This study reported an earlier return to intercourse in the 3-week group than in the retrospectively collected control group where 6-weeks of restriction were advised. This study did not evaluate the impact of early versus later return to sexual activity on wound complications, mesh exposure rates, pain or satisfaction.
It is important to develop evidenced-based recommendations on post-operative sexual activity restrictions.
The purpose of this research study is to understand if the "standard" 6-week restriction on vaginal penetration/intercourse after mid-urethral sling affects patient satisfaction
Full description
The lifetime risk of surgery for stress urinary incontinence in women is 13.6%. Women are typically instructed to avoid strenuous physical activity and vaginal penetration for 6 weeks following synthetic mid-urethral sling procedures. The historical rationale behind these instructions was to prevent disruption of vaginal incisions, promote wound healing, decrease recurrence risk and prevent complications such as mesh exposure. Very little medical evidence exists, however, to support these activity restrictions which can have a negative impact on satisfaction and quality of life. Findings from a single randomized trial challenge standard activity restrictions following pelvic organ prolapse repair. Participants were given conservative or liberal postoperative instructions and the liberal group experienced fewer prolapse and urinary symptoms at 3 months postoperatively; but there was no difference in satisfaction between groups. This study, however, did not investigate restrictions on vaginal penetration (both groups adhered to 6-week restrictions) and was not specific to women undergoing isolated sling procedures. There are no prospective, randomized studies addressing vaginal penetration restrictions following mid-urethral slings. There is a single cohort study examining expedited recovery following vaginal prolapse repair which advised 3-weeks of vaginal penetration restrictions. This study reported an earlier return to intercourse in the 3-week group than in the retrospectively collected control group where 6-weeks of restriction were advised. This study did not evaluate the impact of early versus later return to sexual activity on wound complications, mesh exposure rates, pain or satisfaction.
Animal models suggest that wound healing occurs much sooner than 6 weeks post-surgery. In fact, epithelial wounds closed by primary intention typically re-epithelialize in just 24-48 hours. In a mouse-model with full-thickness vaginal injury, there was complete restoration of mucosal integrity by day 7 without surgical closure of the wound. Epithelial healing over mid-urethral sling could differ due to a known pro-inflammatory milieu in the setting of a mesh implant but the rate of epithelial closure over implanted synthetic mesh has not been specifically described. While earlier vaginal penetration could theoretically increase the risk of mesh exposure from the known baseline risk of 2-3%, this is unlikely following two weeks in a low risk population regardless of menopausal status. Vaginal atrophy has been identified as a risk factor for wound healing complications and vaginal mesh exposure and could interact with early resumption of intercourse. However, vaginal atrophy can be reversed with vaginal estrogen therapy and resultant risks mitigated.
Given the prevalence of mid-urethral slings for stress incontinence, it is important to develop evidenced-based recommendations on post-operative sexual activity restrictions. The purpose of this randomized trial, therefore, is to evaluate the impact of early (2 weeks) versus standard (6 weeks) removal of vaginal penetration restrictions in sexually active women undergoing mid-urethral sling procedures on sexual satisfaction and wound complications.
