Ultrasonography and intravenous pyelography (IVP) were compared for their diagnostic value in 65 patients (29 women, 36 men; mean age 57 [19-85] years) thought to have disease of the kidneys or urinary tract (microhaematuria in 16, macrohaematuria in 5, urinary tract infection in 11, suspicion of renovascular hypertension in 6, suspected tumour in 5, suspected nephrolithiasis in 15, and flank pain of uncertain cause in 7). Ultrasound established an abnormal condition in 29, in five of which IVP gave false positive results, false-negative results in three. The false-negative results were an indirect sign of renal artery stenosis in one patient and in one patient each of duplex ureter and cystic ureteritis. Mild hydronephrosis (n = 3), stone in a kidney or the renal calyx system (n = 2) and tumour of the right kidney (n = 1), diagnosed by ultrasound, were not seen by IVP. Concordant results were thus obtained in 70% of cases. Ultrasound examination of the urinary tract gives such reliable results that in many cases an additional IVP is unnecessary.

A 41-year-old miller undergoing hemodialysis for 9 years presented with recurrent episodes of asymptomatic gross hematuria of a 7 years' duration and left flank pain with slight fever of a four months' duration. CT scans revealed bilateral acquired cystic disease of the kidney (ACDK) and a mass (phi 4 cm) in the medial portion of the left kidney, which was angiographically a hypovascular tumor. Cystoscopic examination revealed multiple papillary tumors arising from the entire bladder wall. These findings suggested that the renal mass was a renal pelvic tumor. Bilateral nephroureterectomy with left paraaortic lymph nodes dissection and radical cystectomy were carried out, followed by urethrectomy two weeks later. Histologically, multiple papillary transitional cell carcinomas with G2 greater than G3 anaplasia were found in the left renal pelvis, the lower portion of the left ureter and the bladder. The tumors were predominantly superficial, although the renal pelvic one focally invaded into the muscular layer. Lymph node metastasis and renal cell carcinoma were not recognized. Postoperative course was uneventful with normal blood pressure, though anemia was slightly progressive. He has been free of disease for six months.

An asymptomatic 73-year-old woman was found to have multiple, simultaneous, inverted papillomas of the renal pelvis and ureter. A review of the world literature yielded 34 cases of inverted papillomas in the upper urinary tract: 13 in the renal pelvis, and 21 in the ureter. Among these 34 cases, there were 26 male and five female patients, with gender not given for three others. Patients ranged in age from 19 to 89 years (mean, 64.1 years). Many cases lacked complete clinical details but, among the others, gross painless hematuria was the presenting symptom in seven; hematuria with flank pain or colic in six; and pain without hematuria in six. Only six patients lacked urinary tract symptoms, and three of these had microscopic hematuria. Only two patients had more than one inverted papilloma, and these were not multicentric. Adequate pathologic documentation and follow-up data were, unfortunately, absent in many of the cases. Although inverted papillomas are curable with surgical resection, with a low rate of local recurrence, they appear to be associated with synchronous or asynchronous carcinomas, especially other transitional cell tumors in the urinary tract.

We report a case of fibroepithelial polyps of the ureter in a 18-year-old boy with the chief complaint of left flank pain. An excretory urogram and retrograde pyelogram revealed left hydronephrosis and a filling defect at the pelvic-ureteral junction. This ureteral disorder was corrected by the renal autotransplantation for conserving the renal function. The pathological diagnosis was fibroepithelial polyps of the ureter. Convalescence was uneventful and after 3 months of follow up, excretory urogram and 99mTc-DTPA renogram showed good renal function and improvement of hydronephrosis. Along with our case, we briefly reviewed 32 cases of ureteral polyp in men under 20 years old.

We report two successfully treated cases of ureteral endometriosis. Case 1 is in a 47-year-old female who had a past history of simple hysterectomy and right oophorectomy. Pathological diagnosis was myoma uteri and pelvic endometriosis. Two months later, she visited our clinic for right flank pain. Excretory urogram and retrograde pyelogram revealed right hydroureteronephrosis and stricture of the right lower ureter. The diagnosis of ureteral endometriosis was made from the past history and clinical features. Danazol therapy started with a daily dose of 400 mg. Sixteen days later, excretory urogram demonstrated complete resolution of the right hydronephrosis. An intravenous pyelography about 1 year after the danazol therapy has indicated no recurrence. Case 2 is in a 35-year-old female who visited our clinic for right lumbar pain. Excretory urogram and retrograde pyelogram revealed right hydroureteronephrosis and stricture of the right lower ureter. Right ureterocystoneostomy was performed unsuccessfully resulting in endoscopic dilation. Right lower ureter was buried in the dense fibrous tissue approximately 5 cm below the crossing with iliac vessels. The area of obstruction was removed. Histologically, endometriosis was diagnosed. Twenty nine cases of ureteral endometriosis including our two cases were collected from the Japanese literatures and reviewed with respect to the clinical features and treatment.

We report a case of retrocaval ureter in a 14-year-old boy with the complaint of right flank pain. Intravenous pyelography and drip infusion pyelography showed right hydronephrosis and "inverted J" shaped ureter. A retrograde pyelography with venocavography revealed a typical retrocaval ureter, but abdominal CT scan did not show the "retrocaval segment". Ureterouretero-reanastomosis was performed and hydronephrosis was markedly improved. We analyzed 20 cases of retrocaval ureter in childhood.

A 7-year-old boy who had been in a traffic accident was hospitalized in Hamamatsu Red Cross Hospital with diagnosis of head abrasion, contusion of abdomen and multiple fractures. On the 17th day of hospitalization, he complained of left flank pain and high fever. Examinations by IVP and enhanced computed tomographic scan revealed a left ureter avulsed at the level of uretero-pelvic junction. Operative reconstruction by end-to-end anastomosis of the ureter was performed immediately. The function of left ureter was recovered 4 months after operation. This rare case of ureteral avulsion is briefly discussed along with a review of the recent literature.

A case of blind-ending bifid ureter is presented. A 65-year-old man was admitted with the complaint of dysuria. He had no past episode of left flank pain or pyelonephritis. Digital examination and urethrography suggested benign prostatic hypertrophy. Drip infusion pyelography showed an abnormal cavity at the lower portion of the left ureter. He was diagnosed as benign prostate hypertrophy and left blind-ending bifid ureter. During suprapubic prostatectomy, the bifid ureter was resectd. The related reports are reviewed in the Japanese literature.

Unusual mode of renal duplication may be confused with supernumerary kidney. The presented adult female complaining left flank pain had bilateral duplication of collecting system with ectopic opening in one of the left-sided ureter. Since the ureteral opening to the bladder neck resulted in giant hydronephrosis in the upper half segment responsible for her complaint, surgical resection was performed. The duplication of the left renal mass and collecting system was regarded as "unusual" in several points. First, the lower half segment of the left kidney looked a normal complete kidney, because it had upper, middle and lower calices. Second, the lower half segment was located rather superior to the upper one. Third, the parenchyma of the upper segment which was a rudimentary small mass of several grams was separated from the lower one. But the left renal artery was single, which supplied blood to not only the lower segment but also the upper one, and the two segments were connected tightly each other by loose areolar tissue. These facts prevented to categorize this case as supernumerary kidney. This case suggests that there may be many transitional cases between fused kidney and supernumerary kidney.

A case of benign ureteral polyps at ureteropelvic junction in a 9-year-old boy is reported. He was hospitalized with episodes of gross hematuria and left flank pain. An excretory urogram showed the left hydronephrosis due to the ureteropelvic junction obstruction. At exploration, we found two polyps at the left ureteropelvic junction. Partial ureterectomy including the polyps and pyeloplasty were performed. Pathological examination showed fibrovascular polyps of the ureter. The patient still remains symptomless for one year after the operation with no signs of recurrent ureteral polyps.
