Antimicrobial mesh versus vaginal wall sling: a comparative outcomes analysis.

PURPOSE: We prospectively compared transvaginal antimicrobial mesh (MycroMesh*) and anterior vaginal wall slings using an outcomes analysis.

MATERIALS AND

METHODS

Between August 1997 and November 1998 we implanted transvaginal slings in 40 consecutive women randomized to a synthetic mesh (20) or vaginal wall (20) group. All patients had documented stress urinary incontinence on preoperative urodynamics. We prospectively compared postoperative outcomes data obtained from pelvic examinations, cough stress test, cotton swab test and validated patient questionnaires using a visual analog scale.

RESULTS

Complete followup was available in all patients. Mean followup was 22 months (range 12 to 27). Stress incontinence was cured in 95% of the mesh and 70% of the vaginal wall group, and pelvic prolapse was cured in 100% and 95%, respectively. Transient de novo urge incontinence was noted in 12.5% of the mesh and 14.3% of the vaginal wall group. Mean postoperative cotton swab angle during Valsalva's maneuver was 20 and 45 degrees for the mesh and vaginal wall groups, respectively. The incidence of urinary retention and tissue erosion was 0% for both groups. The satisfaction rate was 100% and 80% for the mesh and vaginal wall groups, respectively.

CONCLUSIONS

The antimicrobial MycroMesh sling was superior to the vaginal wall sling for correction of stress incontinence and pelvic prolapse with comparatively low morbidity.
