Two cases of submucosal hemorrhage in the renal pelvis and ureter are presented. The roentgenographic appearance was identical to that of pyeloureteritis cystica but without evidence of urinary tract infection and, in 1 case, the submucosal impression resolved rapidly. When nodular, submucosal filling defects are demonstrated in the renal collecting system in the clinical setting of anticoagulant therapy or trauma, a diagnosis of submucosal hemorrhage should be considered.

Two children are presented with similar appearing small urographic defects in the ureter and renal pelvis similar to pyeloureteritis cystica. In one patient with aplastic anemia who died the abnormalities represented areas of subepithelial hemorrhage. Another child had clinically diagnosed Henoch-Schonlein purpura and the defects were probably due to subepithelial hemorrhage.

This is a case report on a patient with left renal stone and ureteritis cystica. The patient was a 57-year-old male, and he was admitted for a thorough examination of his renal stone. Many sharply-defined radiolucent filling defects were detected in the upper and middle ureter by retrograde pyelography, and he was diagnosed with ureteritis cystica. Since the patient had severe renal function damage, left nephro-ureterectomy was performed. This is the 29th case of pyeloureteritis cystica reported in Japan, and here in its clinical aspects are discussed.

A 68-year-old female patient was admitted for the examination of duplication of right ureter and right hydronephrosis. Antegrade pyelography showed multiple, small, round defects in the ureter from the upper pole of right kidney. Ureteroureterostomy was performed under the diagnosis of ureteritis. Including our case, 25 cases of pyeloureteritis cystica have been reported in Japan.

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.

Pyeloureteritis cystica, characterized by multiple bubbly filling defects on urography and caused by inflammatory stimuli, is a rare disorder of the ureter. It commonly affects older people. Diagnosis is established by radiological studies. Antibiotics should be given if urinary tract infection is present. Up to now, no other specific treatment can be used to cure this disorder. We report a case of pyeloureteritis cystica associated with urinary tract infection and a ureteral stone in a young woman who presented with hematuria and bilateral flank pain. The pyeloureteritis cystica had a bead-like appearance on intravenous pyelogram and retrograde pyelogram as well as in magnetic resonance urography. The diagnosis and treatment of this disorder are discussed. Magnetic resonance urography can provide high-resolution of coronal images of the entire urinary tract without the use of contrast agents or ionizing radiation. However, the cost of the procedure is a major concern.
