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-99m-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.
