Abstract

Objective

To determine the time to resumption of normal voiding after a fascia lata sling and whether any clinical, operative, or urodynamic variables predict it.

Methods

Between January 1993 and September 1996, 62 women underwent fascia lata suburethral sling operations for intrinsic sphincter deficiency or recurrent stress incontinence. The demographic, operative, and urodynamic data of 61 of these patients were analyzed.

Results

The mean number of days to resumption of normal voiding was ten. Three patients (5%) developed permanent retention. Patients 65 years and older were more likely than younger patients to have prolonged catheterization (16 versus 7 days, P = .008). Women who had additional procedures voided at a mean of 15 days compared to nine days for those having slings only (P = .029). A preoperative urine flow rate less than 20 mL/sec was associated with late voiding. There was no significant relationship between preoperative voiding mechanism and voiding time.

Conclusion

Resumption of normal voiding occurred earlier than reported by others. Age over 65 years, additional surgical procedures, and low peak flow rates were risk factors for delayed voiding. Time to normal voiding was independent of the preoperative voiding mechanism.
