Combined genitourinary prolapse repair and prophylactic tension-free vaginal tape in women with severe prolapse and occult stress urinary incontinence: preliminary results.
OBJECTIVE
Continent patients with a positive stress test demonstrated on repositioning of severe genitourinary prolapse are considered to be at high risk of developing postoperative symptomatic stress urinary incontinence (SUI). Our aim was to evaluate in a prospective study whether a prophylactic, tension-free vaginal tape (TVT) procedure, performed during prolapse repair, may prevent the development of postoperative SUI in these women.


METHODS
Thirty consecutive, clinically continent women (mean age 64.5 +/- 9.04 years) with severe genitourinary prolapse and occult SUI were prospectively enrolled. Occult SUI was defined as a positive stress test with repositioning of the prolapse during the preoperative urodynamic studies. All patients had urethral hypermobility; none had intrinsic sphincter deficiency. In addition to genitourinary prolapse repair, these patients underwent concomitant TVT to prevent postoperative SUI. Patients were followed up for at least 1 year. Repeated urodynamic studies were performed at 3 to 6 months postoperatively. The main outcome measures were postoperative SUI, persistent or de novo detrusor instability, and recurrence of prolapse.


RESULTS
The mean duration of follow-up was 14.25 +/- 3.08 months (range 12 to 24). None of the patients developed postoperative symptomatic SUI. However, three asymptomatic patients (10%) had a positive stress test during their postoperative urodynamic evaluation. Nine patients (30%) had detrusor instability before surgery, which persisted in six (66%) postoperatively. Postoperative de novo detrusor instability was diagnosed in four other patients (13.33%). None of the patients had recurrent urogenital prolapse, nor did they have clinical evidence of bladder outlet obstruction.


CONCLUSIONS
The preliminary results of TVT as a prophylactic procedure in clinically continent women with severe prolapse and occult SUI are encouraging. Long-term follow-up is required to confirm the durability of these results.
