Abstract
Introduction and Hypothesis: To assess the outcomes of mid-urethral sling (MUS) procedures for urodynamic stress incontinence (USI) following extensive pelvic reconstructive surgery (PRS) and identify risk factors for persistent USI (P-USI). Methods: This retrospective study analyzed 84 women who underwent a staged approach to MUS for USI after PRS for advanced pelvic organ prolapse (Pelvic Organ Prolapse Quantification III and IV). The primary outcome was objective cure rate, defined by negative urine leakage on urodynamic study and a 1-h pad test weight of < 2 g. Subjective cure rate was through a negative response to question 3 of UDI-6. Results: The overall objective cure rate was 81.0%. The highest cure rate was observed in de novo USI (MUS-D; 89.7%) compared with women with persistent USD (MUS-P). Patients with overt SUI exhibited lower cure rates than those with occult SUI. Predictive factors for persistent USI were lower pre-operative maximum urethral closure pressure (MUCP; p = 0.031) and higher BMI in the MUS-P group than in the MUS-D group (p = 0.008). Subjective improvement was noted, especially in the MUS-D group, with a subjective cure rate of 78.6%. Those with MUS-D reported a higher impact on patient well-being post-surgery. No complications were observed after MUS surgery at follow-up. Conclusions: Overt USI, low MUCP and high BMI are independent predictors of persistent USI after a staged MUS approach after pelvic reconstructive surgery.
