Spontaneous nephro-duodenal fistula

Area of Science:

• Gastroenterology and Urology
• Radiology

Background:

• Nephroduodenal fistulas are rare, presenting with upper abdominal pain, pyelonephritis, and renal calculus.
• Inflammatory kidney changes are the most common cause of recent nephroduodenal fistula cases.

Observation:

• This report details two cases: one nephroduodenal fistula and one combined nephroduodenal and nephrocolic fistula.
• X-ray imaging was crucial in precisely identifying the location and scope of the fistulas in both patients.

Findings:

• The fistulas were accurately diagnosed and characterized using monitored X-ray studies.
• Both presented cases involved complex fistulous tracts.

Implications:

• Nephrectomy is identified as the optimal surgical intervention for nephroduodenal fistulas.
• Understanding fistula origins and precise localization is key for effective management.
