Incidence of de novo stress urinary incontinence following minimally invasive sacrocolpopexy.

INTRODUCTION AND HYPOTHESIS: The objective was to investigate the incidence and risk factors of postoperative de novo stress urinary incontinence (SUI) in stress-continent women following minimally invasive sacrocolpopexy without an anti-incontinence procedure.

METHODS

We completed a multicenter, retrospective cohort study of women undergoing laparoscopic sacrocolpopexy without concurrent anti-incontinence procedures from October 2006 through January 2021.

RESULTS

Of the 169 women who underwent minimally invasive sacrocolpopexy, 17.1% (n=30) developed de novo SUI, and 7.1% eventually underwent a midurethral sling placement. On logistic regression, BMI, preoperative urinary urgency, and history of transvaginal mesh repair were found to be significantly associated with and predictive of de novo SUI. When the concordance index (C-index) was calculated with the model published by Jelovsek et al. for women who developed de novo SUI within 12 months of the prolapse surgery, the current de novo SUI calculator was able to discriminate de novo SUI outcome (C-index = 0.71).

CONCLUSIONS

The incidence of de novo SUI after minimally invasive sacrocolpopexy without anti-incontinence procedure correlates directly with higher BMI, preoperative urinary urgency, and transvaginal mesh history for POP. Preoperative counseling for minimally invasive sacrocolpopexy should include discussing the risk of de novo SUI and preoperative factors that may increase this risk.
