Endoscopic holmium laser management of tension-free vaginal tape eroded into the bladder

Abstract

Tension-free vaginal tape (TVT) procedure is not free from intra- and postoperative complications. Diagnosis of mesh erosion is often underestimated by clinicians due to its unspecific symptoms. Urinary symptoms not responding to medical therapy should be investigated by cystoscopy to exclude mesh erosion. We report our experience with holmium laser for the endoscopic management of mesh erosion in three patients. We describe three cases of mesh erosion after TVT placement treated with laser excision of the eroded tape into the bladder. In one case, a 4 × 3 cm stone adhering to the mesh was present. The procedures were performed under spinal anesthesia. The polypropylene eroded mesh was mobilized with forceps to better expose the intramural portion of the sling, and it was disintegrated with holmium laser as close to the bladder mucosa as possible. No complications were recorded. The patients were discharged after 24 h. In only one case, we had recurrent mesh exposure requiring a second procedure. After a mean follow-up of 15.3 months (range 12-20), the patients are asymptomatic with no evidence of tape erosion. Intravesical mesh erosion can complicate sling procedure. Endoscopic holmium laser management is a useful treatment for mesh removal and stone lithotripsy. Repeated treatments are possible for the low morbidity and minimal invasiveness. A regular follow-up is necessary.
