Abstract

Abstract: Objective: To identify urodynamic predictors for de novo overactive bladder (OAB) after single‐incision sling implantation. Methods: This retrospective study analyzed women with pure, urodynamically proven stress urinary incontinence, without OAB, between 2008 and 2015, in a university hospital. De novo OAB was investigated during clinical interviews. Results: A total of 192 patients were analyzed; 21 patients with de novo OAB were considered as group A while 171 control patients formed group B. Univariate analysis demonstrated that patients with de novo OAB have the first desire to void at a lower bladder volume (124 mL versus 160 mL, P = 0.0052), smaller maximum cystometric capacity (357 mL versus 406 mL, P = 0.0061), lower maximum flow (17 mL/s versus 23 mL/s, P = 0.0006), and higher bladder outlet obstruction index (BOOI; −11 versus −23, P = 0.0022) compared with controls. According to multivariate analysis, maximum cystometric capacity (parameter estimate [PE] =0.008, P = 0.04) and BOOI (PE = −0.029, P = 0.01) were independent urodynamic predictors of de novo OAB. The final model showed good predictive accuracy (area under the curve =0.81). Conclusion: The present study identified maximum cystometric capacity and BOOI as independent predictors of de novo overactive bladder after single‐incision sling implantation. Therefore, preoperative urodynamics may be useful to improve preoperative counseling and to tailor surgical treatment. Synopsis: Maximum cystometric capacity and bladder outlet obstruction index were independent predictors of de novo overactive bladder after single‐incision sling implantation.
