Uretero-fallopian fistula after hysteroscopy fallopian tube embolization: a case report.

BACKGROUND: Uretero-fallopian fistula (UFF) is a very rare surgery complication which usually happens after surgeries of fallopian tube or ureter. There has been no report of interventional operations of fallopian tube causing UFF. CASE PRESENTATION: A 41-year-old female received fallopian tube embolization for birth control. After that she noticed "clear vaginal discharge". She neglected that symptom for 7 years, until a sudden onset of abdominal pain brought her to the ER. Retrograde ureterogram confirmed UFF and revealed severe hydronephrosis of the left kidney. She received left nephrectomy afterwards and recovered well, with no urine leakage from her vagina. CONCLUSION: UFF could be caused by interventional operations of fallopian tube, and could lead to severe consequences. The application of fallopian tube embolization should be carefully controlled.
