We recently experienced a case of renal papillary necrosis which we removed by endourological treatment. A 58-year-old female diabetic patient complaining of left flank pain, fever and chills was admitted to our clinic. She had no past history of analgesic abuse or atypical vasculitis. Physical examination revealed a body temperature of 38 degrees C and tenderness in the left costovertebral angle. Pyuria was noted, and urine cultures grew more than 100,000 colonies of Escherichia coli per cubic millimeter. DIP revealed a diminished renal function, hydronephrosis, distorted middle and lower calyces and filling defect in the dilated ureter. However, there was no evidence of obstruction or ureteral reflux. Retrograde pyelography confirmed distortion and irregularity of the calyces and hydronephrosis due to a shadow defect which was movable during radiographic examinations. Laboratory studies revealed anemia, leucocytosis and hyperglycemia, but no elevation of BUN. Therefore, the patient was diagnosed as renal papillary necrosis. We succeeded in its endourological removal through nephrostomy with a choledochoscope (Olympus Co.) under epidural anesthesia. After surgery, the patient made a satisfactory recovery.

A case of long ureteral polyp with ureteropelvic junction obstruction in a 29-year-old man is reported. He had complained of occasional left flank pain since several years earlier. Excretory urography showed left giant hydronephrosis and no urolithiasis. Retrograde pyelography revealed a mass lesion of the left upper ureter. At exploration, the left ureteropelvic junction was found to be obstructed by an aberrant lower pole renal vessel. At just distal of the junction, a finger-like ureteral polyp, 5 cm in maximal length, was present and accompanied with several little polyps. Partial ureterectomy and pyeloplasty improved the left hydronephrosis. The patient remains symptomless for one year after the operation.

The terminology of megaureters, their histological findings and etiology vary greatly in the literature. We encountered an obstructed megaureter in a 39-year-old man. He complained of epigastral and left flank pain. X-ray examination showed a right marked hydronephroureter which compressed the bladder and left ureter. We performed right nephroureterectomy. Postoperative course was uneventful and his clinical condition improved.

A case of emphysematous pyelonephritis is presented. A 49-year-old male with diabetes mellitus complaining of high grade fever attack and right flank pain was referred from internal medicine. KUB demonstrated that the right ureter, pelvis and calyces were filled with gas. Anti-bioticus was given intensively and the abnormal gas shadow on plain film disappeared before RP was done, but high grade fever attack persisted and right nephrectomy was undergone. After this operation, the fever was relieved and the patient was discharged at the 30th day post-operatively. A search of available literature in Japan has disclosed only 17 reported cases. Diagnostic methods, treatment, complication and etiology are discussed.

Aberrant blood vessels are a rare cause of ureteral obstruction, with 9 cases having been reported, mostly in children. A 79-year-old man presented with left flank pain. At operation a patent left umbilical artery was partially obstructing the distal left ureter. Partial ureterectomy and ureteroureterostomy provided relief of symptoms. Aberrant blood vessels should be considered in the differential diagnosis of extrinsic distal ureteral obstruction.

Seven cases of primary ureteral tumors treated at Nagaoka Koseiren Chuo General Hospital in 1983 were reviewed retrospectively. The incidence of primary ureteral tumors among the out-patients in the urologic clinic of the hospital was 0.22% and the incidence among the in-patients was 1.65%. The patient's age ranged from 45 to 83 years (average: 59.14 years old). The ratio of male to female was 2.5: 1.0. The left ureter and the lower third of the ureter were involved more frequently than the others. The most common symptom was colicky flank pain (57% of the cases), which was followed by macroscopic hematuria. On IVP, 5 of the 7 cases showed a non-functioning kidney or hydronephrosis, but the others showed filling defects in the ureteral lumen without hydronephrosis. Diagnostic accuracy of CT was 14.3%. Diagnostic accuracy of urine cytology was 42.9% and the false negative rate was the same. Six of the 7 cases underwent total nephroureterectomy with bladder cuff excision. The higher the grade and stage of the tumor, the poorer the prognosis tended to be.

The terminology of megaureters, their histological findings and etiology vary greatly in the literature. Primary obstructed megaureters must be clearly differentiated from megaureters caused by infravesical obstruction. The characterization and therapeutical consequences of the two types also differ. In a retrospective study, 43 adult patients with 54 primary obstructed megaureters (male:female = 30:13) were studied. This diagnosis excluded infravesical obstruction, reflux and neurogenic disorders. The main symptoms were flank pain, infection and hematuria. An operation was performed in 25 patients; 29 were treated conservatively. The criteria for surgery are discussed in relation to symptoms, functional reserves of the kidney, transportation capacity of the upper urinary tract, and histological changes of the narrow segment of the ureter. Operative treatment should be limited to well-defined complications, such as deterioration of kidney function or recurrent infection, to avoid its discredit as merely a cosmetic procedure.

An 8-year-old boy was admitted because of left flank pain. The excretory urogram showed left hydronephrosis and a filling defect at the pelviureteric junction. Surgical exploration revealed a polypoid lesion on the mucous membrane of the pelviureteric junction and ureteric stenosis due to a periureteric fibrous band. Dis-membered pyeloplasty was performed. The pathological diagnosis was benign fibrous polyp of the ureter. Convalescence was uneventful and an intravenous pyelogram showed no evidence of recurrence one year after operation. We found 13 cases of ureteral polyps in children in the Japanese literature. The differences between ureteral polyps in childhood and those in adults are discussed.

Forty primary renal pelvic tumors treated at our University between 1963 and 1981, were reviewed retrospectively. The conclusions of this study are as follows. Sex and age distribution of the patients were 30 males and 10 females (3: 1), and average age was 60.5 years old. The major symptoms were hematuria and flank pain; however, palpable mass was rare. The majority of patients were admitted to our clinic within 6 months from manifestation of symptoms. The major findings of IVP were non-functioning kidney and filling defect. The positive rate of urinary cytology was 46.7%. Total nephroureterectomy with bladder cuff was performed in 20 out of 32 cases. Histologically, 29 cases were transitional cell carcinoma and 4 cases were squamous cell carcinoma with renal calculi. Simultaneous urothelial tumors were seen in 10 cases, 3 in the ureter and 7 in the bladder. A subsequent ureteral tumor was found in one out of 12 cases in which ureters were resected incompletely, and 7 subsequent bladder tumors were found out of 32 cases receiving surgical treatment in the follow-up period. The 5-year survival rate by the actuarial method was 75.9%. Among several factors, grade and stage of the tumor were the most influencing factors for prognosis. An effective method of post-operative treatment could not be established.

We are reporting a young female who presented with a history of right flank pain and urinary tract infection off and on. On investigation, she was found to have a giant fork-shaped ureteral calculus in a bifid ureter. Since her ipsilateral renal unit was nonfunctioning, nephroureterectomy was performed. Such a case of giant staghorn ureteral calculus in a bifid ureter has never been reported in the world literature.
