Objectives:
To describe my experience of vaginal mesh extrusion using the monofilament polypropylene transobturator sling, the Mentor ObTape. The Mentor ObTape was the first transobturator sling developed as an alternative to the retropubic commercially available suburethral slings for providing mid-urethral support as treatment of female stress urinary incontinence.
Methods:
Thirty patients underwent transobturator suburethral sling placement for anatomic stress urinary incontinence using the ObTape from October 2003 to January 2005. A retrospective chart review was performed to retrieve data on the safety, efficacy, complications, and outcomes using this product.
Results:
Six patients (20%) to date have presented with defective vaginal healing manifested by extrusion of the sling material. Five patients required surgical removal of the sling material, and one underwent a trial of conservative management. No urethral erosions were noted.
Conclusions:
In my experience, the Mentor ObTape sling, which uses a nonwoven, minimally elastic, micropore, monofilament polypropylene mesh, incurs an unacceptably high rate of defective vaginal wound healing and mesh extrusion.
