[Stress urinary incontinence. A comparison of of 4 methods of cystourethropexy. A 2-year follow-up].

All successful operations for relief of genuine stress urinary incontinence (SUI) have three objectives: elevation and retropubic maintenance during stress of the urethrovesical junction. The present study was realized at the Urogynecologic Service of the "Luis Castelazo Ayala" hospital IMSS to evaluate the results in a two years follow up of 597 patients that suffered from SUI treated by retropubic urethropexy, from February 1984 to May 1991. Patients were studied according to the service norms, previously published. We realized four types of procedures: Pereyra (379 cases), Burch (90 cases), Marchall-Marchetti-Kratz (60 cases) and Powell surgery (68 cases). Vaginal approach was realized in cases of pelvigenital statics disturbances like cysto- or rectocele; and abdominal approach was indicated in patients with enlarged uterus or pelvic masses. The complications rate was 15.3%. Success rate was 87.06% for all procedures and not statistic significance was found (p > or = 0.1 and X2 = 6.15), the best rate to the Burch and Pereyra procedures. We conclude the most important tip to successful rate in SUI surgery is correct choice of the procedure according to the patient.
