Vaginal hysterectomy for correcting genital prolapse. Long-term evaluation.

OBJECTIVE: To determine whether a transvaginal hysterectomy with anterior and posterior repair is effective in the long term in treating uterovaginal prolapse and stress urinary incontinence (SUI). STUDY DESIGN: Seventy-four patients subjected to vaginal hysterectomy for the treatment of severe genital prolapse, on average five years before the study, were contacted by letter for evaluation. Four of these patients had died, and 47 (67.1%) responded to the letter. The mean age of the patients at the time of reevaluation was 66.1 +/- 10.6 years, and mean parity was 6.6 deliveries. RESULTS: All patients but two presented some degree of genital prolapse at the time of reevaluation, with three cases of total vaginal vault prolapse. White patients (87.2%) predominated over African (black) patients (12.8%). SUI associated with prolapse persisted in 14 of the 20 patients, and 6 others had this complaint after surgical correction (22.2% of previously continent patients). CONCLUSION: The rate of unsuccessful surgical correction of severe genital prolapse was very high (95.7%), and cure of SUI was low (30%), with SUI actually arising after surgical correction in 25% of continent patients. In addition to parity, there seems to be a racial factor linked to the onset and maintenance of this pathology, with a higher prevalence among white patients.

Evaluation of long-term results of surgical correction of stress urinary incontinence.

A total of 109 patients submitted to surgery for the correction of urinary stress incontinence (USI) by two different techniques, i.e. anterior colporrhaphy (group I, n = 57) when cystocele grade II/III was present, and Burch procedure (group II, n = 52) when cystocele grade I was present, were reevaluated an average of 5 years after surgery (range: 54-66 months). The curve constructed with the reevaluation data showed a sharp superiority of the Burch technique in terms of correction of USI and associated genital prolapses. There was a progressive recurrence rate that stabilized at 5 years, with values of 78.9% in group I and 40% in group II. Anterior colporrhaphy was ineffective for the correction of any of these parameters in group I. The data clearly show the need to improve the presurgical diagnostic methods for the selection of patients that will benefit from treatment: detailed history of the current disease and auxiliary tests such as Q-tip test, transvaginal ultrasound, and urodynamic study. Other factors were associated with ineffective treatment in both groups, such as hypoestrogenism (20/109), excessive weight gain (19/109) and chronic intestinal constipation and/or coughing present in 36 patients, with recurrence in 28 of them.
