[Ureteritis cystica--report of a case diagnosed by biopsy under ureteroscopy].
A 62-year-old male with left ureteritis cystica was reported. Extracorporeal shock wave lithotripsy (ESWL) was performed for his left renal stone 14 and 17 months earlier. However, small fragments remained in the lower calyx and pyuria, microhematuria and bacteriuria continued. Drip infusion pyelography (DIP) showed a small filling defect of the left dilated ureter. Retrograde pyelography revealed multiple, small filling defects of the left middle through the lower ureter. Multiple small submucosal cysts were observed mostly in the pelvic ureter by ureteroscopic examination. Ureteroscopic cold punch biopsy proved ureteritis cystica. The ureteral dilatation improved and filling defects disappeared after the treatment with antibiotics.
