Objective: To verify the efficacy of Raz bladder neck suspension in producingcure of genuine stress incontinence (GSI) in women younger than sixty-five years compared with elderly women, and to find out whether or not elderly patients are more prone to failure with this technique. Method: We reviewed our results with this procedure in 67 women younger than sixtyfive years (group l) compared with 21 elderly women (group II). Seventeen patients in group I and 4 patients in group II had bladder neck suspension for grade I-II incontinence, and 50 patients in group I and 17 in group II had additional cystocele repair by the four-corner technique. Rectocele repair and vaginal hysterectomy were also performed when indicated. Results: With a mean follow-up period of 18.2 months for group I and 16.8 months for group II, 57 women (85.1%) in group I were completely cured of stress incontinence, 6 (8.9%) had marked improvement, and 4 (6.0%) had recurrence, while in group II, 19 (90.4%) were completely cured, 1 (4.8%) had marked improvement, and 1 (4.8%) had recurrence. Namely, in group I, 94 percent of the patients were either cured or improved, as compared with 95.2 percent in group II (P = 0.6; Fisher's exact test). Postoperative complications were few, and there was no permanent urinary retention. Conclusion: We conclude that, in a relatively short-term follow-up, Raz bladder neck suspension is equally successful in curing stress urinary incontinence in young and elderly females.
