Ureteric fistula to small intestine

Last edited: 4/10/2026

Overview

A ureteroenteric fistula is an abnormal connection between the ureter and the gastrointestinal tract, specifically the small intestine. This condition can lead to significant morbidity, including infection and electrolyte imbalances.

Diagnosis

  • Diagnosis is typically made via imaging studies.
  • Intravenous urography (IVU) or computed tomography (CT) urogram can demonstrate the fistula 1.
  • Endoscopic evaluation of the gastrointestinal tract may also be useful 1.

    • Management

  • Management strategies depend on the underlying cause and patient factors.
  • Surgical intervention is often required to close the fistula and reconstruct the urinary tract 1.
  • Temporary diversion, such as a ureterostomy, may be employed in select cases 1.

    • Key Recommendations

  • Diagnosis of ureteroenteric fistula can be aided by intravenous urography or CT urogram 1. (Evidence: Moderate)
  • Surgical intervention is frequently necessary for fistula closure and urinary tract reconstruction 1. (Evidence: Moderate)
  • Temporary cutaneous ureterostomy is a described method for urinary diversion in certain situations 1. (Evidence: Weak)
