Uretero-Jejunal Fistula: A Rare Cause of Acute Pyelonephritis

Penetrating peptic ulcers often lead to severe complications. The development of uretero-enteric fistulas is rare and can be challenging to diagnose and treat. Here, we present the case of a 41-year-old patient who previously underwent gastrojejunostomy for superior mesenteric artery syndrome and developed a peptic jejunal ulcer, leading to a uretero-jejunal fistula and finally causing acute pyelonephritis. The patient was managed with a multidisciplinary approach including medical therapy and endoscopic and radiologic interventions.

Ureteroenteric Fistula Revealed by 99mTc-DTPA Renal Scan

A 55-year-old woman with a history of cervical carcinoma, status post hysterectomy and radiation therapy 8 years prior, presented worsening back pain for 9 months. The patient underwent a Tc-DTPA renal scan, which showed that a vertically linear tracer distribution was seen alongside the right ureter. Ureteroenteric fistula was confirmed and repaired by surgery.
