Perspective study of urodynamic factors with pre-and post-operation overactive bladder symptoms for anterior vaginal prolapse / 中华妇产科杂志

ABSTRACT

Objective To identify pre-operative demographic and urodynamic (UD) parameters related to overactive bladder (OAB) symptoms of pre-operation and persistence of after pelvic organ prolapse (POP) repair.Methods From Jan 1,2010 to Oct 31,2012,this perspective study examined demographic and UD data of 175 patients undergoing POP surgery.Pre-and post-operative urinary distress inventory 6 (UDI-6) scores for frequency and urge urinary incontinence (UUI) were analyzed,and correlations between scores and pre-operative UD data were also analyzed.Results (1)Surgery resulted in a improvement of frequency (71.0％,71/100) and UUI (69.2％,63/91) at 12-24 months follow-up.(2)Pre-operative UD parametersfirst desire of bladder ＜100 ml,6.3％ (11/175); detrusor overactivity,14.9％ (26/175); post-void residual ≥50 ml,11.4％ (20/175); maximal flow rate (Qmax),(16±7) ml/s.(3)Comparison of pre-operative UD datas between patients with OAB symptoms and without,with OAB symptoms group had more patients of type Ⅲ stress urinary incontinence [5％ (5/91) versus 0 (0/84),P=0.022].(4)Qmax was higher in improvement in UUI group than that in persistent UUI after POP repair [(17±7) m]/s versus (13±5) ml/s,P＜0.01].Conclusions POP repair significantly reduces OAB symptoms; however,there had not exact predictor for symptoms of persistent frequency,UUI after POP repair.Persistent UUI symptom may be related to Qmax of pre-operative UD.
