1. Ureteritis and ureteral obstruction secondary to HenochSchönlein purpura (HSP), complicated with subsequent urinoma. 2. Severe gastrointestinal (GI) and ureteral involvement might be due to severe inflammation seen in Familial Mediterranean Fever (FMF), also causing resistance to intense treatment. 3. The patient developed postrenal acute kidney injury (AKI) secondary to ureteral stenosis and a double-J stent was inserted. Kidney functions and electrolyte imbalance improved after insertion of the double-J stent. The patient developed AKI due to double-J stent occlusion three times in the first month of followup and stent revisionwas performed during this period. Computed tomography (CT) imaging demonstrated right perinephric fluid collection with associated hydronephrosis. As regression of hydronephrosis and adequate urine output was observed after recatheterisation, urinoma was allowed to resolve spontaneously. During follow-up, ureteral findings improved at the end of the second month and the double-J stent was removed. Steroid treatment was discontinued gradually after 6 months.
