Comparative Study of Laparoscopic Combined Trans-vesical and Extravesical Versus Laparoscopic Extravesical Fistula Excision in Uterovesical Fistula Repair: A Retrospective Observational Study

• In extravesical approach, the posterior bladder wall and the anterior uterine wall around the fistula will be dissected. Scar tissue around the orifice of the fistula will be removed and trimmed. After suturing uterine and bladder wall, intervening omentum will be placed in-between.

• In the combined approach, bladder will be opened bivalved till the site of the fistula. Scar tissue around the orifice of the fistula will be removed and trimmed. Careful dissection around the bladder and uterus will be done to suture both walls and place an intervening omentum in-between.
