Pyeloureteritis Cystica

In this report, a case with pyeloureteritis cystica caused by urinary calculus disease is presented. The patient had right flank pain and microscopic haematuria was examined by abdominal ultrasound and excretory urography. Multiple nodular radiolucent filling defects as air bubbles were seen in collecting systems especially in renal pelvis and 1/3 proximal ureter. After excretory urography, ureteroscopy and cold cup biopsy were performed and histological examination revealed cystic epithelial appearances and metaplastic changes in uretelium.

Pyeloureteritis cystica is a specific urinary system pathology which is rarely seen but easily diagnosed by excretory urography. Approximately 100 cases have been reported in the literature since the disease was first reported by Morgagni in 1761. The etiology of disease has been usually accepted to recurrent inflammation especially chronic pyeloureteritis by most authors.
