Three Cases of Uric Acid Stone / 대한비뇨기과학회지

We experienced three cases of uric acid stone. We treated all these cases sodium bicarbon with nate for systemic alkalization, 1/10 Molar sodium bicarbonate solution for direct irrigation through urethral & ureteral catheter and allopurinol for decreasing uric acid level and combined surgery was done in two cases, including upper ureteral stone & UVJ stone.

Clinical Observation on the 20 Cases of Renal Tumor / 대한비뇨기과학회지

A clinical observation was made on 20 patients with renal tumor who had been admitted to Department of Urology, Jeonbug National University Hospital during the period from January 1978 to March 1983. The following results were obtained. 1. The incidence of renal tumor among total 1892 inpatients was 1.1% and 5.1% among the 389 genitourinary tumors. The most prevalent age group was fifth decade. The sex ratio, male to female was 1.5:1. 2. Histopathological analysis showed renal cell carcinoma in 11 cases, transitional cell carcinoma in 2 cases, squamous cell carcinoma in I case, Wilms' tumor in 1 case, neuroblastoma in 1 case, hemangioma in I case and simple cyst in 3 cases. 3. The most frequent symptoms and signs were gross hematuria in 11 cases(55%), flank pain in 11 cases(55%) and palpable mass in 6 cases (30%), and these classical symptom triad were seen in 3 cases of renal cell carcinoma. 4. Renal angiography was performed in 9 patients with 6 cases of renal cell carcinoma, 1 case of transitional cell carcinoma, 1 case of hemangioma and 1 case of renal cyst. 5. At the time of diagnosis, distant metastasis were found in 2 cases with renal cell carcinoma to lung, spine and Virchow's node. 6. Treatment of renal tumors consisted of surgery, radiation and/or chemotherapy. Radical nephrectomy was performed in 10 cases, simple nephrectomy in 2 cases, nephroureterectomy with bladder cuff resection in 3 cases, renal cystectomy with marsupialization in 3 cases and only diagnosis in 2 cases.

A Clinical Observation on 7 Cases of Ureteropyeloplasty / 대한비뇨기과학회지

A clinical observation was made on the 7 cases of ureteropyeloplasty secondary to ureteropelvic junction obstruction during the period from July, 1980 to January, 1982 and brief review of literature was made. 1. Hydronephrosis secondary to obstruction at the ureteropelvic junction was caused by congenital ureteropelvic junction stricture in 4 cases, aberrant vessels in 1 Case and combined cases in 2 cases. 2. The youngest age was 15 year old and the oldest 53 year old. The ratio of male to female and left to right were 3:4 and 2:1. 3. The types of ureteropyeloplasty were Anderson-Hynes pyeloplasty in 5 cases, Sand Cormoily tube-flap pyeloplasty in 1 case and nondismembered pyeloplasty with elimination of aberrant vessels in 1 case. 4. Multiple holed stent was used in all cases. 5. Postoperative complications were developed in2 cases, which were intractable urinary leakage and restricture and were treated by nephrostomy and nephrectomy respectively. 6. Follow up study was performed in 6 cases. Among 7 cases of ureteropyeloplasty, good results included in 4 cases, fair in 1 case and poor in 2 cases.

A Clinical Observation on the Nephrectomized Patients / 대한비뇨기과학회지

A clinical observation was made on 70 nephrectomized patients during the period from Jan, 1978 to June, 1981. The results were as follows. 1. The total number of inpatients during the period was 1,122 and nephrectomies were performed in 70 of the 744 total urologic operations (9.4%). 2. The age distribution showed the highest in 5th decade with 25.7% and the youngest case was observed at the age of 3, the oldest at 68 and 43 males and 27 females with male to female ratio 1.6:1. 3. The causative diseases of nephrectomy were tuberculosis (25.7%), renal stone (24.3%), renal injury (14.3%), renal tumor (10.0%) and hydronephrosis (8.0%) etc. 4. Percentage of nephrectomy in each disease were 39.1% in tuberculosis, 22.7% in renal stone, 31.3% in renal injury, 77.9 % in renal tumor and 50.0 % in hydronephrosis. 5. Surgical approaches consisted of frank subcostal approach in 38.6%, anterior abdominal extraperitoneal approach in 35.7 % and abdominal transperitoneal approach in 25.7 %. 6. Among the transfused patients who nephrectomized, the average amount of transfused whole bleed were 1757 ml on renal tumor, 1320 ml in renal injury, 700 ml in renal stone and 533 ml in renal tuberculosis. 7. Postoperative complications were postoperative bleeding in 3 cases, wound infection in 2 cases, paralytic ileus in 2 cases, wound disruption in 1 case, uremia in 1 case and upper G-I bleeding in 1 case.
