Effect of detrusor function on the therapeutic outcome of a suburethral sling procedure using a polypropylene sling for stress urinary incontinence in women.
OBJECTIVE
To assess the effect of detrusor function on the therapeutic outcome of a suburethral sling procedure in women with stress urinary incontinence (SUI).


METHODS
A total of 192 women with SUI who had undergone a suburethral sling procedure were enrolled. According to the baseline urodynamic results, patients' bladder functions were classified as follows: (i) normal detrusor function; (ii) detrusor overactivity; and (iii) detrusor underactivity or acontractile detrusor. Surgical results, urodynamic parameters and patient satisfaction were compared among these three groups.


RESULTS
Overall, 106 patients had normal detrusor function, 36 had detrusor overactivity and 50 had detrusor underactivity or an acontractile detrusor. A continent outcome was achieved in 135 women (70.3%), urge incontinence in 23 (12%), minimal SUI in 32 (16.7%) and moderate SUI in two (1%). Persistent urge incontinence was noted in 13 women (36%) with detrusor overactivity, and recurrent SUI occurred in 18 women (36%) with detrusor underactivity or an acontractile detrusor. No significant change in urodynamic parameters between baseline and after treatment was found in any of the patient groups. The satisfaction rate was 98.1% in patients with normal detrusor function, 82% in patients with detrusor underactivity or an acontractile detrusor and 75% in patients with detrusor overactivity (p<0.05).


CONCLUSIONS
Compared to women with normal detrusor function, those with preoperative detrusor overactivity and those with detrusor underactivity or an acontractile detrusor experienced an unfavorable therapeutic outcome of the suburethral sling procedure in terms of urge incontinence and recurrent SUI after surgery.
