Fistula injury to the bladder at repeat cone biopsy by laser

A 33-year-old woman underwent repeat cone biopsy of the cervix with a carbon dioxide (CO2) laser. At operation the laser caused multiple full thickness fenestrations of the bladder, creating multiple small vesico-vaginal fistulae. The cone biopsy was completed and the fistulae were converted into a single defect which was immediately repaired. The patient went home 'dry'. We believe this is the first such report in the English-language literature.
