There is limited current literature regarding the retreatment of stress urinary incontinence (SUI) after midurethral sling (MUS) placement with prior urethral bulking.
The objective was to evaluate the retreatment and perioperative complications of MUS placement with prior urethral bulking compared with MUS placement without prior urethral bulking.
This was a retrospective cohort study of patients within the Southern California Permanente Medical Group who underwent MUS placement from January 2009 to December 2020. Patients who underwent prior urethral bulking were compared with a control group without prior urethral bulking in a 1:1 ratio matched by age and MUS procedure date. The primary outcome was the retreatment of SUI after MUS placement with prior urethral bulking. Secondary outcomes were perioperative complications. Regression models were used to evaluate associations between retreatment and perioperative complications while controlling for confounding variables.
Eighty-five patients who underwent MUS placement with prior urethral bulking were identified and matched with 85 control patients who underwent MUS placement without prior urethral bulking. Patients who underwent MUS placement without prior urethral bulking were more likely to have concomitant surgery. Linear regression analysis controlling for the effect of concomitant surgery revealed no difference in estimated blood loss and operative time between the 2 groups. In logistic regression analysis, there was no difference in the retreatment rate and perioperative complications between groups.
We found that the unique treatment combination of MUS placement with prior urethral bulking for recurrent SUI seems to have a similar retreatment rate and perioperative complications as MUS placement without prior urethral bulking.
