Aim: This study aims to identify the predictors for detrusor overactivity (DO) in women following extensive vaginal pelvic reconstructive surgery (PRS) for advanced pelvic organ prolapse (POP).
Methods: We enrolled 1503 women who had prolapse POP-Q stage ≥ 3 and underwent vaginal PRS with or without MUS from January 2006 to December 2015. All subjects completed a 72-h voiding diary, IIQ-7, UDI-6, POPDI-6, and PISQ-12. Urodynamics (UDS) was performed pre- and post-operatively.
Results: Among 1503 women, 56 patients were excluded due to incomplete data. Women who had trans-vaginal mesh were 1083 of 1447 (74.8%) and concomitant MUS were 353 (24.4%). Pre-operative DO were 245 (16.9%) and 24.5% (60/245) of them continued to have persistent DO post-operatively. Women who had normal pre-operative stable detrusor were 1202 (83.1%) and 3.5% (30/1202) developed de novo DO post-operatively. The overall incidence of post-operative DO was 6.2% (90/1447). Patients with age ≥66 year, neurological factors like Cerebrovascular accident and Parkinsonian disease, pre-operative bladder outlet obstruction (BOO) maximum urethral closure pressure (MUCP) ≥60 cmH2 O, Maximum flow rate (MFR) <15 mL/s and detrusor at maximum flow (Dmax) ≥20 cmH2 O) and post-void residue (PVR) ≥200 mL hold a significant higher risk of developing DO either persistent or de novo following PRS.
Conclusion: Age ≥66 year, neurological factors like CVA and Parkinsonian disease, pre-operative MUCP ≥60 cmH2 O, MFR < 15 mL, Dmax ≥ 20 cmH2 O, and PVR ≥ 200 mL are independent risk factors for developing post-operative DO following vaginal PRS for advanced POP.
