title: Success rate of modified Pereyra bladder neck suspension determined by outcomes analysis.
abstract: The reported success rates of the modified Pereyra bladder neck suspension vary from 51 to 90%. Retrospective chart review studies have reported cure rates of 77 to 90%. In contrast, a questionnaire based outcomes analysis, using a strict definition of cure, reported 51% of the patients to be cured of stress urinary incontinence after modified Pereyra bladder neck suspension. We conducted a questionnaire based outcomes analysis of the modified Pereyra bladder neck suspension at our institution. The objectives of the study were to determine the success rates of this procedure using strict criteria in an outcomes analysis format, assess the overall satisfaction of patients postoperatively and identify historical factors that may be predictive of outcome. Between September 1988 and December 1991, 151 patients underwent a modified Pereyra bladder neck suspension for urodynamically documented genuine stress urinary incontinence. Mean patient age was 56 years (range 19 to 82 years) and mean followup was 25 months (range 9 to 45). All patients had type 2 incontinence (anatomical) based on history (severity of symptoms), physical examination, and fluoroscopic assessment of the bladder neck and urethra. Preoperative pad use, and irritative and obstructive symptoms were retrospectively assessed, and a preoperative Stamey incontinence score was assigned. A standardized questionnaire was used to compare preoperative and postoperative voiding symptoms, perception of urinary control and satisfaction with the decision to undergo an operation. Followup telephone calls were made by a trained registered nurse not associated with the original procedure. Postoperative pad use also was quantified and a postoperative Stamey score was assigned. A total of 106 patients (70%) returned the questionnaires. Cure was strictly defined as no urine leakage under any circumstance. While 78% of the patients required no to minimal protection postoperatively, 50 (47%) reported cure of the stress urinary incontinence, 68 (64%) reported subjective improvement, 27 (26%) were the same and 11 (10%) were subjectively worse after modified Pereyra bladder neck suspension. Of the patients 77% were satisfied with the decision to undergo the operation. Patients subjectively worse were significantly older than those subjectively improved (66 versus 54 years, p = 0.05). Postoperative failures had significantly higher obstructive and irritative symptom scores. Questionnaire based outcomes analysis has consistently demonstrated success rates less than those reported in retrospective chart review studies. Outcomes analysis, based on patient assessment of satisfaction, may more accurately reflect the expected surgical outcome after a modified Pereyra bladder neck suspension. We emphasize the need for standardized questionnaires and outcomes analysis to evaluate patient satisfaction with surgery designed to improve quality of life.
