Unusual bilateral obstructive uropathy with kidney failure in an adolescent with ulcerative colitis

Extrarenal manifestation and complications of inflammatory bowel disease may be detected in a significant number of patients. It is known that the genitourinary tract may be affected but data from childhood population are scarce. We present an unusual bilateral obstruction of ureters, inflammation of bladder wall and vesicoureteral reflux in a boy with ulcerative colitis. Obstructions led to recurrent acute kidney injury with need of surgical intervention to prevent kidney function deterioration.
