CLINICAL AND URODYNAMIC PREDICTORS OF DELAYED VOIDING AFTER FASCIA LATA SUBURETHRAL SLING

Objective: To determine the time to resumption of normal voiding after a fascia lata sling and whether any clinical, operative, or urodynami c variables predict it. Methods: Between January 1993 and September 19 96, 62 women underwent fascia lata suburethral sling operations for in trinsic sphincter deficiency or recurrent stress incontinence. The dem ographic, operative, and urodynamic data of 61 of these patients were analyzed. Results: The mean number of days to resumption of normal voi ding was ten. Three patients (5%) developed permanent retention. Patie nts 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 day s for those having slings only (P = .029). A preoperative urine flow r ate less than 20 mL/sec was associated with late voiding. There was no significant relationship between preoperative voiding mechanism and v oiding time. Conclusion: Resumption of normal voiding occurred earlier than reported by others. Age over 65 years, additional surgical proce dures, and low peak now rates were risk factors for delayed voiding. T ime to normal voiding was independent of the preoperative voiding mech anism. (Obstet Gynecol 1998;92:608-12. (C) 1998 by The American Colleg e of Obstetricians and Gynecologists.).
