STUDY OBJECTIVE: To determine the outcome of voiding function 1 year after pelvic reconstructive surgery (PRS) in women with bladder outlet obstruction (BOO).
DESIGN: Retrospective cohort study.
SETTING: Tertiary referral hospital.
PATIENTS: A total of 1894 women underwent PRS for advanced pelvic organ prolapse (POP) stages 3 to 4 with urodynamic findings of BOO.
INTERVENTIONS: PRS.
MEASUREMENTS: The primary outcome measured was the resumption of normal voiding function, defined clinically with multichannel urodynamic testing at 1 year postoperatively. The secondary outcomes were to identify the different risk factors for persistence voiding dysfunction (VD) 1 year after PRS.
MAIN RESULTS: A total of 431 women with Pelvic Organ Prolapse Quantification stages 3 and 4, urodynamic study of maximum urinary flow rate ≤15 mL/s, and detrusor pressure at maximum flow ≥20 cm H2O were included. Resumption of normal voiding function was found in 91% (n = 392 of 431), whereas 9% (n = 39 of 431) remained to have VD 1 year postoperatively. Those with persistent VD, 20.5% (n = 8 of 39) remained having urodynamic diagnosis of BOO. Univariate and multivariate logistic regression revealed factors associated with postoperative VD were pre-operative maximal cystometric capacity ≥500 mL and postvoid residual volume ≥200 mL.
CONCLUSION: VD may persist in women with BOO after PRS, particularly in those with preoperative maximal cystometric capacity of >500 mL and postvoid residual volume >200 mL.
