Endoscopic management of transvaginal mesh kit bladder extrusion: A case report and literature review

Abstract

Objective: A rare complication of transvaginal synthetic mesh kits is bladder mesh extrusion. Treatment options include abdominal or vaginal surgical mesh excision or endoscopic mesh vaporization. There are very few published studies detailing endoscopic management. This unique case describes how repeated endoscopic mesh vaporization may be required as mesh extrusion may progress. Methods: A 71-year old female with a history of pelvic organ prolapse managed with an anterior transvaginal mesh kit presented years later with persistent urgency incontinence and recurrent acute cystitis. Cystoscopy eventually revealed bladder calculi adherent to extruded mesh. The stones and extruded mesh were vaporized using the Holmium laser on three occasions over 3 years. Results: Our approach offered a minimally invasive technique with short recovery, no use of a catheter post-operatively and maintained original prolapse repair; however, these patients may be at risk of mesh extrusion recurrence. Conclusion: Bladder extrusion of transvaginal pelvic organ prolapse kit mesh is thankfully a rare complication. With no current consensus for treatment of bladder mesh extrusion, the decision to perform complete mesh excision versus endoscopic treatment should be based on the degree and location of the extrusion, the risk of major complications, mesh extrusion recurrence and the patient’s desired outcomes, including recovery time and risk for prolapse recurrence. Endoscopic vaporization of extruded pelvic organ prolapse mesh likely has a higher recurrence rate than vaginal or abdominal excision. The risks and benefits are important to discuss during counseling and informed consent in these difficult cases. Level of evidence: 4
