This study was undertaken to identify risk factors for postoperative voiding dysfunction and factors having impact on patient global satisfaction after a tension-free vaginal tape (TVT) procedure. Two hundred and eighty-five women who underwent the TVT procedure for stress urinary incontinence were analyzed to identify risk factors predictive of voiding dysfunction. Postoperative voiding dysfunction was defined as a peak urinary flow rate (PFR) <10 mL/sec (straining voiding, n=17) or residual urine volume >30% of bladder capacity (incomplete emptying, n=13). The global satisfaction rate was 91.6%. Voiding dysfunction developed in 29 (10.2%) patients. Among the factors, PFR was only factor of significance for voiding dysfunction. There was no significant difference between patients with and without voiding dysfunction in terms of their satisfaction. But postoperative PFR <10 mL/sec significantly compromised global satisfaction after the surgery. In those patients with a preoperative PFR <20 mL/sec, there were more patients with postoperative PFR <10 mL/sec. Peak urinary flow rate is an important factor for the postoperative voiding dysfunction. The inevitable decline in PFR can compromise patients' satisfaction with the procedure, when their postoperative PFR was <10 mL/sec.
