[Sling removal after the Vesica sling and tension-free vaginal tape (TVT) procedures].
OBJECTIVE
We describe our experience of sling removal performed after either the Vesica sling procedure (due to vaginal erosion or at the time of reoperation for recurrent stress incontinence) or the tension-free vaginal tape (TVT) procedure (due to persistent urinary retention).


METHODS
From May 1997 to December 2002, we performed 19 Vesica sling procedures and 66 TVT procedures for the treatment of urodynamic stress incontinence. In the former procedures, four patients (21%) developed vaginal erosion and underwent total or partial removal of sling material (Hemashield made from bovine-collagen-injected woven polyester). In another three patients, stress incontinence recurred 2-4 years after the Vesica sling procedure, and they underwent total sling removal and the TVT procedure. Before using the urethral pull-down process (UPDP) in TVT procedures, 2 out of 23 patients (8.7%) developed persistent urinary retention and underwent either sling release alone or partial sling removal concomitant with a second TVT procedure. After the introduction of the UPDP, no patient developed urinary retention.


RESULTS
Three patients in whom total sling removal was performed due to vaginal erosion after a Vesica sling procedure developed recurrent stress incontinence. One patient who underwent partial sling removal remained continent, but vaginal erosion recurred 2 years later. Patients who had total sling removal and TVT procedures due to recurrent stress incontinence after Vesica sling procedure became continent with an uneventful postoperative course. One patient who underwent transvaginal release of TVT tape (polypropylene mesh) due to urinary retention after the TVT procedure developed recurrent stress incontinence, and the other who underwent partial removal of TVT tape and a second TVT procedure had resolution of urinary retention without recurrence of stress incontinence.


CONCLUSIONS
Prompt and total sling removal should be recommended for vaginal erosion after the Vesica sling procedure. In patients with urinary retention after the TVT procedure, partial removal of TVT tape and a second TVT procedure using the UPDP to prevent overtightness may be a preferable choice to attain both continence and resolution of urinary retention.
