Colorenal fistula and urinary tract infection in a pediatric patient with acute lymphoblastic leukemia.

Introduction: Colorenal fistula is rare in the pediatric population. It may occur at any segment involved by ischemia, chronic inflammation, or necrosis. It is typically associated with a preliminary renal lesion that may arise as a result of interventional procedures, inflammatory conditions, colon tumor, and xanthogranulomatous pyelonephritis, among others.

Case Report: 15-year-old female patient diagnosed with acute lymphoblastic leukemia admitted at our institution for baseline condition management. During her stay, she experienced gastrointestinal and urinary infectious events. In the assessment and management of those, a left colorenal fistula was found. Surgical treatment was decided upon.

Discussion: Colorenal fistula typically occurs secondary to renal inflammation or infection. Clinical signs are highly variable, and treatment is surgical, with the fistulous tract being resected in all cases.
