Rare Case of Left-Sided Ureteroduodenal Fistula

Abstract

Background/Aims: Ureteroduodenal fistulas are rare and only 11 cases have been reported in the literature since 1918. Diagnosis requires careful observation of symptoms. Methods: The case presented demonstrates a 68-year-old female with left-sided ureteroduodenal fistula confirmed by CT scan. A duodenal fistula was localized and an atrophic left kidney was identified and repaired. Results: Nephroureterectomy was performed and an omental patch was used for the repair. No complications were encountered during the postoperative course. Conclusions: Recurrent chronic urinary tract infection, pyuria and hematuria can indicate this rare disease. Early testing and detection can improve the chances of renal preservation.

Uretero-duodenal fistula: Risk factors and management

“…Although the patient in our case is only the third known female patient to have UDF, there are similarities to the previously reported cases in the literature. 4 , 5 The first female patient described with UDF was also treated with nephroureterectomy and fistulectomy. 4 Evidence of chronic infection in the form of a right XGP kidney, and also a concurrent large PUJ calculus, likely contributed to UDF development in our patient.…”

The subsequent instrumentation of this chronically infected urinary system may also have increased the risk of fistula formation.…”
