Abstract:
Objective To analyze the risk factors of voiding dysfunction after mid-urethral sling surgery for stress urinary incontinence.Methods Clinical data of 573 consecutive patients undergoing midurethral sling surgery from January 2003 to December 2010 were collected and analyzed retrospectively.All relative risk factors were evaluated by univariate and multivariate Logistic analysis to identify risk factors of voiding dysfunction.Results Voiding dysfunction occurred in 28 patients,with an incidence of 4.9％ (28/573).Univariate analysis showed that age,previous pelvic surgery,pre-operative postvoid residuals,maximum flow rate,average urine flow rate,Valsalva leak point pressure,concomitant anterior pelvic repair and operator performing＜50 procedures were the relative risk factors (P＜0.05) for voiding dysfunction.Multivariate logistic regression analysis revealed that the maximum flow rate (Qmax) ≤ 15 ml/s (OR=3.782,P=0.003) was an independent risk factor for voiding dysfunction and surgery experience was its protection factors (OR=0.295,P=0.016).Conclusions Qmax ≤ 15 ml/s on preoperative urodynamic study is an independent risk factor for voiding dysfunction after mid-urethral sling procedure.Improving skill of surgery and strengthening technical training will help to reduce the incidence of this complication.
