Predictor of de novo stress urinary incontinence following TVM procedure: a further analysis of preoperative voiding function.
OBJECTIVE
The purpose of this study was to evaluate the predictors of de novo stress urinary incontinence (SUI) in patients undergoing a tension-free vaginal mesh procedure (TVM) for pelvic organ prolapse (POP).


METHODS
Sixty-five patients without SUI were assessed with regard to voiding function by a pressure flow study and clinical characteristics.


RESULTS
The mean age of the patients was 67 ± 8.3. Of the 65 patients, 41 (63 %) maintained urinary continence postoperatively and 24 (37 %) showed de novo SUI. In univariate analysis, the de novo SUI group included a significantly higher proportion of patients with preoperative obstruction, defined as moderate or greater obstruction according to the Blaivas nomogram (29 vs 7 %, P = 0.035). In multivariate analysis, urethral obstruction was an independent predictor of de novo SUI with an odds ratio of 12.616 (95 % confidence interval 1.580-268.731).


CONCLUSIONS
Preoperative evaluation of urethral obstruction will contribute to prediction of de novo SUI combined with a conventional diagnosis of occult SUI.
