The radiological changes of renal papillary necrosis are independent of its etiology. If total papillary necrosis (TPN) or partial papillary necrosis (PPN) is present, radiological findings are diagnostic. Whereas, if the necrotic papillae remain in situ (NIS) none of the typical radiologic features of papillary necrosis are seen. Serial radiologic studies are useful in renal papillary necrosis. Extension of papillary or medullary cavities, shrinkage of the kidney, and calcification thereby may be noted. Radiologic changes involving the ureter and bladder are those of complications such as ureteritis or development of a transitional cell carcinoma. The latter most often appears in the renal pelvis.

The authors describe a modified method of antireflux operation in vesico-ureteral reflux in children. It consists in transvesical mobilization of the distal ureteral portion together with the urethra and placing it in the tunnel, formed in muscular layer of the urinary bladder from the site of physiological ostium obliquely downward and inwardly. Thirty operations after the describe technic were performed in 17 patients. Four operations were accomplished in the left ureter, 14 patients were operated bilaterally, including 11 cases when one-moment bilateral antireflux operations were performed. The immediate results of surgery were good. In none of 11 examined children during 1-3 years postoperative reflux was noted. In one case of marked hydroureter with ureteritis signs after the operation stenosis of the transplanted sotium developed.

Fifty-two patients with obstructive diseases of the upper urinary tract were treated by percutaneous endoscopic surgery between May, 1986 and July, 1989. Fifty-nine procedures consisting of endopyelotomy (24 procedures), endopyeloureterotomy (29) and balloon dilation under direct vision (6) were performed in 54 units of the urinary drainage system. Causative diseases were congenital in 24 units, scar due to calculi in 17, scar due to previous surgery in 11 and tuberculous ureteritis in 2. The postoperative follow-up periods ranged from 3-41 months, mean +/- S.D.; 12.2 +/- 7.3 months. Of the 59 procedures, 49 (83.1%) achieved improvement but 10 could not on the postoperative excretory pyelogram and/or TcDTPA renogram. Three procedures (5.5%) required blood transfusion. Retroperitoneal leakage of the perfusate was observed in 3 procedures (5.0%). No other severe complications were observed. These results indicate that this procedure may be used for the reconstructive surgery in obstructive diseases of the upper urinary tract such as the ureteropelvic junction and the proximal 1/3 ureter.

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 63-year-old woman with the complaints of left renal stone and fistula between left ureter and colon was transferred to our clinic by a local doctor. Anemia, gamma-globulinemia, and acceleration of ESR were detected by hematology on admission. Kidney-ureter-bladder X-ray and intravenous pyelography showed left non-functioning kidney with coral stone, and RP revealed a fistula between left ureter and sigmoid colon. She was operated by nephroureterectomy and fistulectomy. The resected kidney appeared pale and parenchyma was almost replaced by yellowish tissue and pus. Histologically, the lesion was confirmed to be xanthogranulomatous pyelonephritis. Meanwhile, the cause of the fistula was considered to be due to extending ureteritis and pelvic infection from the pyelonephritis. Postoperative course was satisfactory.

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 review of 49 cases of rare ureteral and pelvic diverticula enables certain clinical and radiologic conclusions to be drawn. Lesions were bifid ureters with blind branches (20 cases), single (8 cases) or multiple (10 cases) diverticula of ureter and pelvic diverticula (11 cases). As previously reported, ureteral diverticula produced few clinical signs whereas these were marked in pyelic lesions. Multiple diverticula are particularly difficult to detect, but diagnosis is the rule from radiologic appearances and is generally confirmed by results of therapy. Their pathogenesis is poorly understood, however, mainly due to lack of histologic data, but recent studies by Cochran suggest they are a particular from of ureteritis. The only debatable point is the frequent association of multiple diverticula with bladder tumor, described by Cochran and confirmed by the authors and unlikely to be the result of chance. Further studies are necessary to provide clarification.

A 50-year-old Japanese male hospitalized with the complaint of fever and pyohematuria. An excretory pyelography revealed the right hydronephroureter due to right ureteral stone. When the ureterolithotomy was carried out, a wide-based and rice-sized tumor co-existed at the site of the epithelium of the ureter lithotomized. Resected tumor was pathologically confirmed as poorly differentiated adenocarcinoma with mitosis. Therefore, total nephroureterectomy with bladder cuff resection was done at 10 days after the first operation. However, malignant cells were not found in the surgical specimen or histologically diagnosed localized glandular ureteritis. He is alive without any evidence of recurrence. It was reported that the glandular metaplasia, a relative rare lesion in the ureter, was correlated with carcinogenesis of adenocarcinoma in urothelium. However, when the lesion is small and localized such as in this case it should be treated with ureterectomy and addition of other suitable adjuvant therapies. Furthermore, endourological techniques which have been recently dramatically progressed may become a weapon against this lesion for both treatment and follow-up.

Benign fibrous polyps of the ureter are rare. A review of the English literature since 1930 revealed that 71 cases had been described. Three additional cases of fibrous ureteral polyps, one in a ureter with ureteritis cystica, are reported with a discussion of both the histologic findings and proposed treatment plan.

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.
