Assessing outcome after a modified vaginal wall sling for stress incontinence with intrinsic sphincter deficiency

Forty women with stress incontinence, intrinsic sphincter deficiency (ISD), associated or not with urethral hypermobility, a Valsalva leak point pressure (VLLP)<60 cmH(2)0 and a maximum urethral closure pressure<30 cmH(2)0 underwent in situ vaginal wall sling. The main modification to the technique was the use of two small Marlex meshes placed at the lateral edges of the sling. Outcome was assessed by pad use, surgical results and patients' satisfaction. Data of 39/40 patients were analyzed after a minimum follow-up of 1 year. After surgery 30/39 patients were completely dry (no pads), stress incontinence disappeared in 22/39, and 30/39 patients were satisfied with outcome. Reasons for dissatisfaction included recurrence of stress incontinence in three, infections in one and urge incontinence in five. Overall results are good given this category of patients. The vaginal wall sling can be recommended for patients with ISD because the results are promising, it corrects urethral hypermobility and, in our experience, it does not cause obstruction if correctly performed.
