Ureteritis cystica - A rare urological condition.

Ureteritis cystica is a rare benign condition. In this report, we have presented the case of a patient with a left upper back pain. The CT scan showed multiple irregular filling defects in the upper left ureter and the left renal pelvis. During the ureteroscopy, multiple yellow cystic lesions were seen in the proximal part of the left ureter and in the renal pelvis. The pathology report described cystic structures coated with single line cubic metaplastic epithelium. Ureteritis cystica should be considered in a differential diagnosis, in case of atypical radiological findings. No active treatment is required when confirmed.
