We present a case of idiopathic retroperitoneal fibrosis that demonstrated a remarkable response to steroids. The patient, a 73-year-old man, complained of left flank pain and weight loss. Erythrocyte sedimentation rate was elevated and both CRP and antinuclear factor were positive. DIP showed left hydronephrosis, which proved to be due to the stenosis of the left ureter at the level of L5 by retrograde pyelography. Then abdominal computed tomography revealed a large retroperitoneal mass with the density of soft tissue in which the left ureter was involved. Based upon the above findings, we made the diagnosis of idiopathic retroperitoneal fibrosis. After confirming histological diagnosis by biopsy from the mass, we performed left ureterolysis. Since then, he has been treated with steroid administration. Now we can recognize a remarkable reduction of the mass in abdominal CT and improvement of the left renal function in DIP. We reviewed the association of autoimmune disease with idiopathic retroperitoneal fibrosis and recent therapies for this disease.

A 68-year-old woman was hospitalized complaining of right flank pain. The excretory pyelogram revealed that the right kidney was hydronephrosis, and a retrograde pyelogram showed stringy filling defects in the middle portion of the right ureter. Suspecting a right ureter tumor, a right ureteronephrectomy was performed. The pathological diagnosis was ureteral cholesteatoma which is a rare condition with reports of only 9 cases in the Japanese literature. Although the possibilities of malignant change has been debatable, long term follow up would be mandatory.

A case of ureteral polyp in a 7-year-old boy with the chief complaint of left flank pain was reported. The excretory urogram and retrograde pyelography showed left hydronephrosis and a filling defect at the pelvic-ureteric junction. Partial resection of the ureter containing the lesion and Anderson-Hynes pyeloplasty were performed. The pathological diagnosis was benign polyp of the ureter. Convalescence was uneventful and excretory urogram showed improvement of the hydronephrosis. Along with our case, 19 cases of ureteral polyp in childhood are briefly discussed.

Retroperitoneal fibrosis is rarely considered in the differential diagnosis of ureteral obstruction in children even when clinical presentation and radiologic findings are typical. In a 12-year-old boy admitted with a 2-week history of flank pain computed tomography showed an enhancing mass obstructing the left ureter. Pathologic examination of the mass and adjacent segment of ureter revealed retroperitoneal fibrosis.

We present a case of ureteral endometriosis in a 48-year-old postmenopausal patient who was hospitalized complaining of right flank pain & microhematuria. She had no bladder irritability. She had a past history of simple hysterectomy and left oophorectomy because of adenomyomatosis. At that time, right ovary and other pelvic organs were normal. Physical examination revealed slight swelling of the liver without tenderness. Laboratory data at admission revealed severe liver dysfunction due to liver cirrhosis. Excretory urography demonstrated right hydronephroureterosis and severe stricture of the right lower ureter. Right ureteral catheterization demonstrated a high degree of stricture at the distal third. Cytology of right pelvic urine was negative. Right nephroureterectomy was done because long segment of right lower ureter adhered to the peritoneum tightly and we could not rule out ureteral cancer. Pathological diagnosis was extrinsic endometriosis of the right ureter. Ureteral endometriosis is rare and postmenopausal endometriosis is also rare. In our case hyperestrogenemia caused by liver cirrhosis might have played a role in the genesis and progression of endometriosis.

Thirty-four cases of tumor of the renal pelvis or ureter or both have been treated in our department during the past decade. The primary tumor was in the renal pelvis in 11 cases, in the ureter in 21 cases and in the ureter and renal pelvis in 2 cases, a co-existent tumor in the bladder was found in 4 cases. Seventeen patients had a tumor on the right side and 17 on the left side. The most frequent symptom was gross hematuria (70.6%) and flank pain was the presenting symptom in 7 cases (20.6%). On the intravenous pyelography, a filling defect in the renal pelvis or ureter (41.2%) and nonvisualization (53.0%) were frequent findings. Twenty-nine cases had undergone total nephroureterectomy with resection of a bladder cuff, 3 had simple nephrectomy and 2 had open biopsy alone. Postoperative radiation therapy was done in 1 case, chemotherapy in 10 cases, and 6 cases of them were treated by CAP therapy (cis-dichlorodiamine platinum, doxorubicin and cyclophosphamide). Actual and relative 5-year survival rates were 53.8% and 63.5%, and no significant difference was found in survival rate between the patients with renal pelvic tumors and those with ureteral tumors.

A rare case of ureteral hemangiomatous granuloma is reported. Colicky flank pain and gross hematuria are the main symptoms and a long cord-like filling defect in the right ureter is noted on excretory urography (IVP). The possible cause and proper treatment of the disease are discussed.

A 12-year-old girl complained of left flank pain 4 months after the onset of symptoms of polyarthritis nodosa with hypertension, multiple neuritis and impaired renal function. Intravenous pyelography (IVP) revealed no stone. Several months later the flank pain recurred, and IVP now showed a calcified stone midway in the left ureter. Ureterolithotomy was performed, and a 3 cm long stone embedded in the mucosa was removed. Two months postoperatively IVP showed severe ureteric obstruction due to stenosis at the level of the incision. Dilation of the stricture was accomplished with a 4 mm balloon, and further dilation 2 weeks later with a 6 mm balloon. A third dilation was performed with a 4 mm balloon. At examination 3 months later the girl was free from symptoms and IVP with forced diuresis was normal, as were the findings after 6 more months. Transluminal balloon dilation of postoperative ureteral strictures in children should be considered as an alternative to surgery.

We report a case of neurofibroma of the ureter without other clinical signs of von Recklinghausen's neurofibromatosis. The patient presented with flank pain, and excretory urography, retrograde urography and computerized abdominal tomography demonstrated a ureteral mass. The light and electron microscopic characteristics, as well as the histogenesis of ureteral neurofibroma, are discussed.

A case of primary amyloidosis localized to the inferior renal pelvis of a kidney with a duplex collecting system is described. The onset of gross hematuria and mild flank pain necessitated investigations which yielded a clinical impression of tumor within the lower pelvis of a duplex collecting system. At laparotomy a grossly hemorrhagic-appearing mass in the lower pelvis was noted and a left ureteronephrectomy was undertaken. Histologic examination of the surgical specimen revealed amyloid deposition within the inferior pelvis, the corresponding distal portions of the papillae, and the most proximal ureter. Amyloid was not present elsewhere within either the renal parenchyma or the superior collecting system.
