Abstract Our objective was to report our initial experience with extracellular matrix material derived from porcine urinary bladder, MatriStem, in patients with vesico vaginal fistula (VVF). Materials and methods: For our retrospective review, we obtained the medical records of 40 consecutive patients who were seen for VVF during our 2 years study period. All patients underwent a thorough evaluation, including history, physical, examination, computed tomography urography, and single-dye pad tests. The cases were treated with two different kinds of MatriStem to repair VVF. Results: In 6 patients, the MatriStem procedure was performed by robotic surgery, in these cases a MatriStem graft were used; in 3 cases we injected micronized particles of MatriStem via cystoscopy and vaginoscopy. The mean follow-up 7.25 months. We observed that 75% of the cases had no fistula drainage per the vagina and progressed to full healing. Conclusion: MatriStem in our early results seem to have a role in effectively treating VVF. Further investigation and long term follow up is needed to establish MatriStem as An alternative treatment for VVF patients.
