Abstract
Background: Incidence of intraoperative vaginal perforation is generally considered to be low but varies among different procedures. Vaginal perforation could not only prolong the surgeries and aggravate surgical trauma but also result in postoperative discomfort or even a second surgery.
Method: Vaginal perforation, vaginal epithelial perforation, vaginal wall perforation, vaginal penetration, urinary incontinence were searched in PubMed, Cochrane, Embase database to identify the qualified clinical trial and relevant literature sources were also searched.
Results: A total of 9223 cases of from 33 trials from literatures and 387 cases from our own trail were analyzed, which provided detailed data on intraoperative vaginal perforation. Incidence of intraoperative vaginal perforation during mid-urethral sling surgery treating stress urinary incontinence was generally low, which was 1.56%. Incidence of intraoperative vaginal perforation during transobturator (TOR) procedure was higher than that during retropubic (RPR) procedure, which were 2.11% and 0.89% respectively. Incidence of intraoperative vaginal perforation during outside-to-inside TOR procedure like TOT and MONARC was higher than that during inside-to-outside TOR procedure like TVT-O, which were 2.74% and 1.52%, respectively. Incidence of intraoperative vaginal perforation during single-incision surgery like H-type TVT-SECUR reached 1.97%, while no report on U-type TVT-SECUR surgeries.
Conclusion: The incidence of intraoperative vaginal during mid-urethral sling procedures for female stress urinary incontinence is fairly high. Vaginal perforation was more common in trans-obturator route (TOR) than retropubic route (RPR). In TOR route, it was less frequent in inside-to-outside procedure than outside-to-inside procedure. Surgery proficiency could also have an impact on this complication.
