Paravaginal defect repair in the treatment of female stress urinary incontinence and cystocele.

OBJECTIVES

To assess the functional and anatomic results of the paravaginal defect repair (PVdR) in women with stress urinary incontinence (SUI) due to bladder neck hypermobility (BNH) and cystocele.

METHODS

Fifty-two consecutive patients with a mean age of 61 years underwent PVdR for the treatment of SUI associated with BNH and varying degrees of vaginal prolapse. Twenty-five patients underwent PVdR alone (group 1), and 27 underwent PVdR in association with a rectus muscle sling (group 2) for the treatment of intrinsic sphincter deficiency. All patients had SUI and lateral defect cystocele (paravaginal defect). Associated vaginal and pelvic floor defects included rectocele in 34, vault prolapse in 24, and enterocele in 18; these defects were repaired simultaneously and had an equal distribution among the two groups.

RESULTS

At a mean follow-up of 17 months, the cure rate (defined as no pads and no leakage) was 79% (group 1, 72%; group 2, 85%). When expanded to include substantially improved (1 pad/day or less), the success rate was 88% (group 1, 84%; group 2, 93%). Recurrent vaginal prolapse occurred in 8 patients, 6 of whom had PVdR alone. For those patients with failure, time to recurrence of incontinence was 15 and 23 months in groups 1 and 2, respectively.

CONCLUSIONS

PVdR restores the normal lateral attachment of the pubocervical fascia to the arcus tendineous fascia pelvis of the pelvic sidewall and provides anatomic repair of lateral defect cystoceles. In women with anatomic SUI, PVdR restores continence by alleviating BNH and should be used in conjunction with a sling procedure in those with intrinsic sphincter deficiency.
