Ureteritis cystica associated with xanthogranulom atouspyelonephritis

Abstract

Ureteritis cystica (UC) and xanthogranulomatous pyelonephritis (XP) are rare, benign conditions that uncommonly appear together. The first one has not well established etiology yet and can affect ureter, renal pelvis and bladder. The second one is a chronic renal infection resulting in severe kidney deterioration and destruction. Both of these entities are usually unilateral. They both cause wide spectrum of symtoms so the diagnose can be difficult to establish. We report the case of a 68 year old male with a history of intermittent macroscopic hematuria, left flank pain, recurrent urinary tract infection and calculosis of left kidney. We describe the imaging and endoscopic investigations leading to the diagnosis of ureteritis cystica as well as the treatment options.
