Clinical Observation on the Ureteral Diseases in Pediatric Patients / 대한비뇨기과학회지

A clinical observation was made on 20 ureteral diseases in 17 pediatric patients who had been admitted to the Department of Urology, Hanyang University Hospital, from May 1972 to February 1982, and the following results were obtained. 1. Pediatric patients with ureteral diseases were 17 of 2584 total urologic patients giving a ratio of 0.6%, and of 359 total pediatric patients 4.7%. 2. The preschool children (1 to 6 years of age) were most frequently seen (14.2%). The proportion of male to female was 3.3:1. 3. The most common disease was congenital UPJ obstruction (60%). The other diseases were UVJ obstruc tion, V-U reflux, ureterocele with complete double ureter subsequently. 4. The most common manifestation included flank pain in 9 cases, fever and chilling in 7 cases, hemturia in 5 cases, gastrointestinal syruptome in 5 cases, palpable mass in 4 cases subsequently. 5. The most common associated disesses were 2 cases of the renal stone in UPJ obstruction. 6. Of the 20 cases, 12 cases underwent dismembered pyeloplasty, 4 cases ureteroneocyst0stomy, 2 cases heminephrectomy with ureterectomy. The remained 2 cases were treated with conservatively.

A Clinical Observation on 124 Cases of Hydronephrosis / 대한비뇨기과학회지

A Clinical observation was made on 124 cases of hydronephrosis in the department of urology, Hanyang University Hospital during 8 years and 7 months from May, 1972 to December, 1980. The following results were obtained: 1. The rate of hydronephrosis accounted for 5.2% of the total patients (2385 cases) admitted to the Department of Urology. 2. The patients in this series ranged from a 1 month old female to a 78 years old male patient. The most common age group was the 3rd decade (26.6%). The male and female ration was 1.8:1. 3. The left side was affected 1.7 times more than the right, 12 cases were bilateral (9.7%). 4. In etiology, acquired ureteral stricture was most common (34 cases-27.4%) followed by congenital UPJ stenosis (26 cases-20.8%). In children there were 7 cases (43.6%) of congenital UPJ stenosis and the male and female ratio was 1.8:1. In acquired ureteral stricture. 25 cases (73.5%) were due to renal tuberculosis. 5. Among the symptoms on admission flank pain occurred in 53 cases (35.5%), and hematuria in 23 cases (16.6%). The duration of the symptoms in most cases was 12 months or more (33%). 6. By urinalysis pyuria was found in 71 cases (57.2%). Urine culture was performed in 65 cases and E. coli was detected in 18 cases (27.7%). B.U.N. was elevated in 17 cases (14.5%) and creatinine 8 cases (6.5%). 7. Cystoscopy was performed in 97 cases. Abnormal cystoscopic findings were seen in 45 patients (46.4%). 8. 123 operation were performed in 112 of 124 patients. Nephrectomy and ureteronephrectomy were done in 38 cases (28.3 %), urinary diversion 13 cases (9.6%) and ureteroneocystostomy 12 cases (8.9%). In 26 cases of congenital UPJ obstruction (congenital UPJ stenosis and aberrant renal vessel and fibrotic band), 4 of 11 cases (35.4%) were nephrectomized from May, 1972. to December, 1976 and 3 of 15cases (20%) were nephrectomized from January, 1977 to December, 1980.

A Case of Ectopic Ureteral Orifice Associated with Ipsilateral Renal Agenesis / 대한비뇨기과학회지

The renal agenesis and ectopic ureter were relatively rare congenital disease, but their combined form was more extremely rare condition. We report a case of ectopic ureteral opening associated with ipsilateral renal agenesisthat noted recurrent epididymitis in 18 month old children with review of literatures.

A Case of the retroperitoneal Malignant Fibrous Histiocytoma / 대한비뇨기과학회지

Malignant fibrous histiocytoma is uncommon pleomorphic tumor of the soft tissues possibly arising from the histiocyte. A case of malignant fibrous histiocytoma of the retroperitoneum stimulated our interest in this uncommon and pathologically intriguing lesion. So we report a case of malignant fibrous histiocytoma in the retroperitoneal space.
