ABSTRACT
We herein report a case of pyelitis cystica in 65-year-old woman. She was referred to our hospital in order to have a treatment for a stone in the ureter on left side. Excretory urogram showed hydronephrosis on left, and multiple, small, smooth and round filling defects in the renal pelvis on right side. ESWL was performed to the ureteral stone, and the stone was discharged completely in 4 days. Then further examinations were made for the filling defects of right renal pelvis. Nonopaque calculi were ruled out on retrograde pyelogram and CT scan. Urinary cytology from the renal pelvis was class I. Our impression was pyelitis cystica of right kidney. Under spinal anesthesia, ureterofiberscopy was performed. Multiple small cysts were observed in the pelvis and calyx, as well as cystitis cystica. Cold cup biopsy was also done and histopathological finding ws pyelitis cystica, without malignancy. We compared endoscopic findings with radiographic findings in 18 cases of pyloureteritis cystica from the Japanese literature. The radiographic findings were multiple small, in a uniform size, and round filling defects with regular contour, and the endoscopic findings were multiple white or ocher colored, half sphere or sphere shaped, and small cyst with smooth surface in 15 of 18 cases. We thought these findings were characteristic ones in pyloureteritis cystica. Endoscopy and biopsy are mandatory for diagnosis of pyeloureteritis cystica.
