We report a case of primary fibroepithelial polyp of the left ureter. The patient was a 34-year-old-man, complaining of left flank pain. An excretory urogram and retrograde pyelogram revealed left hydronephrosis and filling defect of the middle third of ureter. It was difficult to make a differential diagnosis with ureteral tumor. A frozen section revealed no malignancy and we performed partial ureterectomy and end-to-end anastomosis. We discussed the clinical features of adult primary ureteral polyp reported in the Japanese literature.

A case of retroperitoneal xanthogranuloma is reported. A 51-year-old man was referred to our hospital for the evaluation and treatment of right flank pain and hydronephrosis. Intravenous urography (DIP) and retrograde pyelography revealed the stricture in the middle portion of the right ureter. Ureteroscopy revealed no mucosal lesions. Computed tomography revealed the paraureteric mass lesion. Partial ureterectomy, mass resection and uretero-ureterostomy were performed. Then a double J stent was left in place for 6 weeks. The stricture was due to a yellowish mass adhered to the right side of the ureter. The resected mass measured 1.0 x 2.0 x 1.0 cm. The histopathological diagnosis was xanthogranuloma. The patient is in good health without recurrence 4 months after the surgery.

A case of renal vein thrombosis in a seventy-five year old female was reported. She complained of severe left flank pain. The symptoms and signs resembled obstruction from a ureteral calculus. The kidney-ureter-bladder X-ray showed a calcification in the pelvic cavity. She was admitted under the initial diagnosis of left ureteral stone. The venous phase of renal arteriography revealed venous collaterals (ureteric vein and gonadal vein). Selective renal phlebography demonstrated a radiolucent area. Warfarin, 6 mg orally daily, has been administered for a year. It has effectively prevented subsequent emboli. This was a rare case of renal vein thrombosis in an old patient, because it was not associated with nephrotic syndrome or thromboembolic state and because it presented as sudden onset.

A case of spontaneous peripelvic extravasation associated with primary ureteral tumor is reported. A 56-year-old woman presented with left flank pain. Excretory urogram and abdominal computed tomographic (CT) scan demonstrated left hydronephrosis with extravasation of contrast materials around the renal pelvis. Retrograde pyelogram showed the filling defect in the left upper ureter. Under diagnosis of ureteral tumor, total nephroureterectomy was performed. Histological findings revealed transitional cell carcinoma. 80 cases of spontaneous peripelvic extravasation in Japan were reviewed and discussed briefly.

Two cases of endometriosis causing ureteral stenosis are reported. Case 1. A 46-year-old woman was hospitalized with the complaint of right flank pain. Intravenous pyelography showed right hydronephrosis and retrograde pyelography revealed ureteral stenosis at the distal third ureter. Exploration revealed an abnormal periureteral mass, which was excised together with the distal part of the ureter. A right ureteroneocystostomy was performed with the Boari technique. Case 2. A 39-year-old woman was hospitalized with the complaint of pain in the left lower quadrant. A left retrograde pyelography showed stenosis of the ureter at 4 cm proximal of the bladder. An exploratory laparotomy revealed blue berry spots on the left side of the uterus and dense fibrous tissue around the ureter, which was successfully dissected out. The pathological diagnosis of both cases was extrinsic ureteral endometriosis. Ureteral endometriosis has rarely been described and the literatures on 30 cases reported in Japan were reviewed.

Dilatation of the upper urinary tract occurs in more than 80% of pregnant women during the last half of pregnancy. It is caused by compression of the ureter between the growing uterus and linea terminalis. A few patients develop pathological dilatation, flank pain and impaired renal function, a so-called symptomatic hydronephrosis. We have treated ten patients by means of internal drainage by using double pigtail catheters. Nine patients were completely relieved of their symptoms, and one reported marked reduction of pain. Five women complained of irritation of the bladder. In three of the women the intravesical portion of the catheter was shortened with success. Eight women kept the stent up to the time of birth. Two were removed two and eight weeks before delivery because of infection. There were no serious complications. Use of double pigtail catheters is a safe and simple way of treating symptomatic hydronephrosis of pregnancy.

A case of simultaneous bilateral renal pelvic tumors is reported. A 64-year-old man with the chief complaint of gross hematuria and left flank pain was admitted. Clinical investigations revealed a tumor in the right pelvis and ureter, and another tumor in the left renal pelvis. The right ureteral tumor had invaded the bladder. Right nephroureterectomy, total cystectomy, left partial pyelectomy and ureterocutaneostomy were performed. By pathological examination, right renal pelvic and ureteral tumors were non-papillary transitional cell carcinoma, grade 3, pT4, and the left renal pelvic tumor was papillary transitional cell carcinoma, grade 2, pT1. To our knowledge, this is the 16th case of simultaneous bilateral urothelial tumors of the upper urinary tract in Japan.

A 30-year-old female was admitted to our hospital complaining of hematuria and right flank pain in September, 1987. She had been diagnosed idiopathic thrombocytopenic purpura in 1980, and had similar symptoms before. Hematoma in the right ureter was demonstrated by retrograde pyelography and CT-scanning, and these symptoms improved within one month. Each activity of plasma clotting factors was within normal limits. Enzymatic studies of the urine revealed low values of plasmin-, urokinase-, and kallikrein-like activities in both excerbation and remission. These hemorrhagic tendencies might have been the result of marked thrombocytopenia: After bleeding into the urinary tracts began, the bleeding would tend to form hematoma because of elevated clotting activity; then hematoma would grow due to decreased urine fibrinolytic activities. This suggested that a decline of fibrinolysis in urine might have a promoting effect on the process of hematoma formation.

A case of primary carcinoma in situ of the ureter in a 77-year-old man is reported. The patient had been to another hospital with right flank pain and macroscopic hematuria. Ultrasound sonogram showed right hydronephrosis. An excretory urogram showed right hydronephrosis and stenosis of right ureter. He was referred to our hospital for further evaluation and treatment. Retrograde pyelogram demonstrated a right ureteral stricture at the level of S1-2, but no space occupying lesion was detected in the ureter. Cytology of voided urine was negative for malignant cells and no other abnormal findings were present. Probe laparotomy was performed under the preoperative diagnosis of ureteral stricture. During the operation, frozen section examination of the stenotic ureter showed carcinoma in situ and so we performed right total nephroureterectomy with a bladder cuff. Pathologic diagnosis was primary carcinoma in situ of the right ureter. The patient has been doing well for six months postoperatively with no evidence of recurrent or metastatic disease.

During the last ten years, 16 patients have been treated for urothelial carcinoma of the upper urinary tract, ten carcinomas of the renal pelvis and six carcinomas of the ureter. Mean age at the time of diagnosis was 64.3 years. The most common symptoms were hematuria, flank pain and loss of weight. The diagnosis was established by intravenous pyelography and retrograde ureteropyelography. Ureteral carcinomas were operated with local resection of the ureter, while carcinomas of the renal pelvis were treated with a nephroureterectomia. Most tumours were highly malignant. Four tumours were non-invasive and, in retrospect, could have been treated with a local resection only. Only 35% of patients with urothelial carcinoma in the upper urinary tract are alive five years after diagnosis.
