Abstract

Colorenal fistula is a rare condition resulting from chronic inflammation, malignancies, diverticulitis, or infection. This case examines a 68-year-old female with a history of urinary urgency, left back pain, and recurrent urinary tract infections. Anteroposterior non-contrast computed tomography scan showed a large stone in the renal pelvis and gas in the collecting system. Left ureteroscopy revealed multiple ureteral polyps. Retrograde pyelogram revealed contrast filling the left colon. Ureteral polyp biopsies were benign, and colonoscopy was negative for malignancy. This case describes the occurrence of a colorenal fistula in a patient with no history of surgery, malignancy, or diverticulitis.
