Postoperative voiding function in patients undergoing tension-free vaginal mesh procedure for pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: We compared pre- and postoperative voiding function in patients with POP and assessed the efficacy of urodynamic studies in these cases.

METHODS

Forty-six patients treated with the tension-free vaginal mesh (TVM) procedure between January 2009 and February 2010 underwent pressure flow study pre- and postoperatively. Pre- and postoperative voiding functions were assessed according to Schäfer nomograms.

RESULTS

The mean postoperative detrusor pressure at maximal flow was decreased significantly compared with that preoperatively. The mean maximum flow rate was also improved significantly and the proportion of normal contractility was increased significantly after the operation, as was the proportion of non-obstructive patients.

CONCLUSIONS

The TVM procedure for pelvic organ prolapse improved both detrusor contractility and urethral obstruction.
