title: [Uretero-fallopian fistula secondary to low anterior resection for rectal cancer].
abstract: A 71-year-old woman presented with lower abdominal pain and urinary incontinence 18 days after low anterior resection for rectal cancer. Computed tomography and magnetic resonance urography revealed right hydronephrosis, cystic mass in the right pelvic cavity and hydrometra. Positron emission tomography showed dilated right upper urinary tract communicating with dilated right fallopian tube and uterine body, and the finding was quite characteristic. Laboratory studies revealed that the serum and the fluid from hydrometra levels of creatinine were 1.06 mg/dL and 6.15 mg/dL, respectively. We diagnosed this case as uretero-fallopian fistula. Since the conservative management of uretero-fallopian fistula with ureteral stent was not accomplished, she underwent right ureteroureterostomy and adnexectomy. The intraoperative findings included dilated right ureter and fallopian tube adherent to the stenotic right ureteral segment ligated by suture during prior surgery. The histopathological findings showed endometriosis and inflammatory changes of uterine appendages. Follow-up at 3 months demonstrated resolution of the urinary incontinence and the ureteral obstruction and fistula.
