[Pyelo-duodenal fistula complicating pyelonephritis].

Area of Science:

• Urology
• Gastroenterology
• Nephrology

Background:

• Pyeloduodenal fistula is a rare complication, often associated with severe renal inflammation.
• Gravidic pyelonephritis (kidney infection during pregnancy) can lead to fistulous tract formation.

Observation:

• A case of pyeloduodenal fistula secondary to gravidic pyelonephritis is presented.
• Diagnosis was confirmed using intravenous urography.
• The likely cause was an undiagnosed dysectasia (abnormal dilation) of the pyelo-ureteral junction.

Findings:

• The patient underwent successful treatment with nephrectomy (kidney removal) and duodenal suture (intestinal repair).
• Recovery was achieved following surgical intervention.

Implications:

• Percutaneous nephrostomy is highlighted for its diagnostic and prognostic value in managing this rare fistula.
• Early diagnosis and appropriate management are crucial for favorable outcomes in pyeloduodenal fistula cases.
