The coexistence of an obstruction at the ipsilateral ureteropelvic and ureterovesical junctions is rare, the diagnosis of which is not usually made preoperatively. In such cases, the second obstruction can be recognized by the intraoperative findings or on postoperative urologic examinations. Here, three cases of the coexistence of these two conditions are reported.

Giant hydronephrosis is a clinical entity in which errors of diagnosis are frequent due to the silent development of this pathologic state. We present a case which has been considered worthy of detailed report for various reasons. First, it was a 22 liter hydronephrosis which is, so far as can be discovered from available Korean literature, the largest that has been removed surgically. Secondly, despite of huge hydronephrosis, the patient experienced delivery.

PURPOSE: It may be difficult to differentiate renal cell carcinoma involving collecting system from renal urothelial tumor invading into renal parenchyma. The purpose of this study was to assess the differences of CT findings between two conditions. MATERIALS AND METHODS: CT findings of 5 cases of renal cell carcinoma involving the renal collecting systems and 10 cases of renal urothelial tumors invading the renal parenchyma were compared, and analyzed about the presence or absence of hydronephrosis, normal or abnormal CT nephrogram, renal contour changes due to mass and tentative diagnosis. The diagnoses were confirmed at surgery. RESULTS: Renal cell carcinoma showed hydronephrosis in only 20% and normal CT nephrogram and outward contour bulging in all cases. In contrast, renal urothelial tumor showed hydronephrosis(70%), abnormal CT nephrogram(60%), and preservation of reniform shape(100%). CONCLUSION: Renal contour changes and CT nephrogram may be useful in distinguishing both disease entities.

The coronal sectional image of computerized tomography creates an image that is similar to an excretory urogram. It also provides more clearly delineated renal image and image of adjacent organs than an excretory urogram. Further more, the number, extent, and content of renal mats lesions used to discriminate density difference can be determined with relatively great accuracy. This image of computerized tomography is useful to understand and make a diagnosis of renal disease. Coronal sectional image of computerized tomography is more informative in evaluation of retroperitoneum space than conventional radiography. Recently we observed several cases of renal disease-renal cell ca, simple renal cyst, angiomyolipoma, retroperitoneal teratoma, pheochromocytoma, hydronephrosis which could be detected with coronal sectional image of computerized tomography.

A case of giant hydronephrosis containing 9,500 cc, simulating ascites due to 'cirrhotic liver in a twenty. three year old male, is presented. The differential diagnosis and the important clinical, laboratory and X-ray features are discussed with brief literatual review.

UItrasound provides the ideal means to examine the fetal developing organs and during the last few years urogenital anomalies in fetus have been discovered with increasing frequency. Obstuctive and non-obstructive urinary tract dilation have been diagnosed in utero as early as l4 weeks gestation and intrauterine intervention designed to relieve hydronephrosis have been performed even at 2l weeks gestation. The major benefit of prenatal ultrasound is to permit early identification of the fetus at risk and to enable treatment to be performed in the neonatal period before infection intervens to worsen the prognosis further. Recentry we have experienced 2 cases of fetal uropathy which was detected with obsterical ultrasonography and treated with neonatal corrective surgery.

A kidney containing more than 1,000ml fluid in its collecting system is generally defined as giant hydronephrosis. The clinical manifestations of giant hydronephrosis are indistinct. The patient seems to seek medical help late due to tolerable symptoms and particularly in the state of poor economic condition. We present a giant hydronephrosis of contents of 60 liters associated with ureteropelvic junction stricture on a 43-year-old woman. The final diagnosis was performed by exploration of abdomen and nephrectomy was done.

Endometriosis represents extrauterine nonneoplastic endometrial tissue. It is most commonly diagnosed in women of childbearing age, with a peak age of 40 to 44 years. The incidence of genitourinary involvement ranges from 1% to 2%. Ureteral endometriosis is a rare entity, and its diagnosis requires a high index of suspicion. We report a case of ureteral endometriosis in a 44-year-old multiparous woman with a brief review of literature.

Glassy cell carcinoma is an unusual neoplasm of the uterine cervix with highly aggressive clinical behavior. On cervico-vaginal smear examination, the tumor has well confused of atypical repair cell of the endocervix. Recently, we have experienced two cases of glassy cell carcinoma of the uterine cervix, diagnosed on cervico-vaginal smears and confirmed on following histologic sections. The cervico-vaginal smears revealed abundant clusters with well defined boarders. The cell clusters were composed of large tumor cells. The tumor cells had distinct granular cytoplasm and eosinophilic macronucleoli. Characteristic cytologic features of this tumor were discussed in view of differential diagnosis.

Widespread use of fetal ultrasonography is accompanied by more frequent detection of antenatal hydronephrosis. Therefore, sonographic evaluation of neonates with a history of antenatal hydronephrosis is becoming more widespread. As an initial postnatal non-invasive imaging modality, ultrasonography is used to screen for persistence of hydronephrosis, determine the level and severity of obstruction, and contribute to appropriate diagnosis and treatment. This review aims to provide a practical overview of the sonographic evaluation of neonatal hydronephrosis and to describe the sonographic findings of conditions associated with hydronephrosis in the newborn.
