PREOPERATIVE URODYNAMIC EVALUATION MAY PREDICT VOIDING DYSFUNCTION IN WOMEN UNDERGOING PUBOVAGINAL SLING

ABSTRACTPurpose: We determine which urodynamic parameters can best predict postoperative voiding dysfunction following pubovaginal sling surgery.Materials and Methods: The records of 98 consecutive women who had undergone pubovaginal sling surgery with allograft fascia lata between July 1998 and July 2000 were reviewed. Urodynamic and followup data were sufficient for evaluation for 73 patients. Urodynamic and clinical parameters were correlated with urinary retention, time to return of efficient voiding and development of postoperative urgency symptoms.Results: Average time to return of efficient voiding was 3.92 days (median 3). Of 21 women who voided without a detrusor contraction urinary retention developed in 4 (23%) versus 0 of 48 who voided with detrusor contraction (p = 0.007). Urinary retention was defined as the need to perform even occasional self-catheterization. All 4 women with urinary retention had a detrusor pressure of less than 12 cm. H2O (0 in 3, 4 in 1). None of the women with a detrus...
