Objectives To evaluate the effects of preoperative low maximal flow rate ( Q max) on voiding trials after the midurethral sling ( MUS ) procedure in women with stress urinary incontinence ( SUI ). Methods One hundred and sixty‐eight women who underwent MUS procedure were enrolled. Preoperative free uroflowmetry was performed and patients were divided by Q max. Low Q max was defined as a Q max under 15 mL/sec with voided volume at least 150 mL. Surgical results, failure of voiding trial, and postoperative uroflowmetry parameters were compared between the groups. Failure of voiding trial was defined by a PVR more than 100 mL on postoperative uroflowmetry. Results At the discharge day, there were 42 cases showing failure of voiding trial and 33 cases requiring CIC , but only one patient showed failure of voiding trial at 12 months postoperatively. Overall, 48 patients had preoperative low Q max. Low Q max group showed lower Q max in all of postoperative uroflowmetry, but there were no significant differences in the rate of postoperative voiding trial failure or CIC . The low Q max group was then divided into two groups according to the preoperative detrusor pressure at Q max over and under 20 cmH 2 O in pressure flow study. Comparing the two groups, no significant differences were observed in the cure rate, voiding trial failure or CIC . Conclusions Our results suggest that women with preoperative low Q max experienced no definite unfavorable voiding problem from the MUS procedure compared to those with normal voiding function. MUS procedure may be regarded as a safe and successful procedure in SUI women with low Q max.
