A histologic analysis of 10 cases of Wilms` tumor in the department of Urology, Chosun University Hospital during 11 years periods from January, l975 to December, l985 has been carried out. A classification based on the tumor differentiation and degree of tubular formation are described. A comparison of the histologic findings with the survival was undertaken and it was found that the histologic classification was significantly correlated with survivals. The results were as follows : I. Low grade tumors(grade I) with predominance of differentiated tubules were associated with a better cure rate than high grade tumors(grade IH) composed mainly of undifferentiated spindle elements : 2 year or more survival rate was lOOf6 for grade I but O% for grade III. 2. Cure rate was lower for the low degree of tubular formation than for the high degree of tubular formation : 2-year cure rates were O%, O%, 33.3%, lOO% for group O, +,++ and +++ respectively. 3. 6 patients with the focal or diffuse anaplasia and sarcomatous stroma had a bad prognosis. giving a survival rate of 0%.

Immunoperoxidase localization of carcinoembryonic antigen (CEA) and ferritin antigen was performed on tissue sections of 16 transitional cell carcinoma in the urinary bladder. On the basis of the cellular degree of atypias and mitotic figures and the architecture of the papillary pattern, transitional cell carcinoma was graded from I to III. The results are as follows: 1. Immunohistochemical localization of C.E.A in the transitional cell carcinoma, form Grade I to III shows intracytoplasmic positive reaction with increasing tendency in the superficial layer. 2. Immunohistochemical localization of ferritin in the transitional cell carcinoma, Grade I , shows entirely negative reaction. The transitional cell carcinoma, Grade III, shows more strong intracytoplasmic positive reaction rather than Grade II. 3. Immunohistochemical localization of CEA and ferritin in the infiltrating nests shows intracytoplasmic positive reaction anaplastic cells.

The analysis of urinary calculi is an essential step in the examination and initial treatment of the patient with urolithiasis. Among the various methods of stone analysis, we have used x-ray diffraction method for analyzing urinary calculi. The advantage of x-ray diffraction is its almost absolute identification of crystalline materials and mixtures of crystalline materials. The disadvantage of x-ray diffraction include initial high cost of equipment and inability to identify amorphous materials and constituents present in only minor or trace amounts. We have analyzed 127 urinary calculi by x-ray diffraction method, which were obtained from the patients who were admitted to the Department of Urology, Chosun University Hospital during the period of 5 years from Jan. l98l to Dec. l985. The following results were obtained: 1. In this studies, 8 crystalline components of urinary calculi were demonstrated: Calcium oxalate monohydrate, Calcium oxalate dehydrate, Calcium oxalate trihydrate, Hydroxyl-apatite, Magnesium ammonium phosphate hexahydrate, Calcium hydrogen phosphate dihydrate, Uric acid and Cystine. 2. Calculi of single component, comprising 73 (57.6%) of the total, was more common than those of mixed component, 54 (42.4%) of the total. Calcium oxalate monohydrate was the most common pure calculi, composing 46 (36.2 %) of all pure calculi and mixed calcium oxalate monohydratecalcium oxalate dihydrate calculi was the most common mixed calculi, constituting 20 (15.7%) of all mixed Calculi. 3. Classifying author`s results as Jensen`s classification, pure calcium oxalate and calcium oxalate apatite mixtures composed 87.3% of total, magnesium ammonium phosphate-apatite mixtures constituted 4.O%, uric acid comprised 6.5%. 4. Among the all urinary components analyzed in this studies, calcium oxalate monohydrate was the most common constituent, composing 78% of the total and calcium oxalate dihydrate was the second common constituent, comprising 37.6%, calcium oxalate was the most common component, composing 9l.3% of the total. 5. In the components associated with calcium oxalate monohydrate, calcium oxalate dihydrate was the most common associated component, in calcium oxalate dihydrate calcium oxalate monohydrate, in hydroxyl-apatite calcium oxalate monohydrate, in uric acid calcium oxalate monohydrate 6. According to the distribution of urinary component in each urinary organ, calcium oxalate (esp. calcium oxalate monohydrate exceeded 50%) was the most common component in entire urinary tract, which comprised 59.1% of all renal calculi, 69.4% of all ureteral calculi, 33.3% of all bladder calculi and 100% of all urethral calculi. 7. Of 44 renal calculi, 30 were composed of staghorn calculi, in which calcium oxalate was the most common component, constituting 56.6% of 30 staghorn calculi.

Neonatal urologic urgencies are any genitourinary condition during the 1st month of life that jeopardizes the gonads, the kidneys, or the life of the infant if there is a delay in either diagnosis or treatment. Since 1991, we have experienced 41 cases of neonatal urologic urgencies. Of 41 cases, 23 were detected prenatally. Male to female distribution was 29 to 12. The initial symptoms or signs at presentation were antenatal hydronephrosis in 21, fever in 10, scrotal mass in 5. The rest 5 were 1 abdominal mass, 1 cystic adrenal mass, 1 absence of kidney, 1 abnormal micturition and 1 jaundice. The final diagnosis were 1 neuroblastoma, 2 multicystic dysplastic kidney, 1 multicystic dysplastic kidney and contralateral UPJO, 2 unilateral transient hydronephrosis, 3 bilateral transient hydronephrosis, 1 unilateral renal hypoplasia and contralateral hydronephrosis, 1 unilateral and 2 bilateral UPJO, 1 renal agenesis, 5 complete duplicate ureter, 3 primary megaureter, 1 unilateral UVJ0, 2 unilateral and 9 bilateral VUR, 1 PUV, 1 congenital megalourethra with bilateral hydronephrosis, 1 acute epididymitis, 3 torsion of spermatic cord, 1 cystic teratoma. Surgical treatment was performed in 26 and conservative management in 15. Since it has been reported 2/3 of all infant deaths occur during the 1st year of life, especially most are during the neonatal period, we believe it is crucial that urologists be involved in the care of newly born infants and be alert to the clues of underlying genitourinary abnormalities or diseases because the least easily recognizable urologic abnormality may be the one that requires the most immediate attention in the neonate.

A clinical observation was made on 274 cases of urolithiasis among the number of 1,122 inpatients during 3 years and 6 months from January 1978 to June 1981. The results are summerized as follows: 1. The incidence of the patients with urolithiasis was 22% of the inpatients. 2. The age of the patients ranged from 2 to 82 years old, with the highest incidence in 20-49 in age (69.6%). 3. The cases consisted of 75 cases with renal stone (27%), 161 cases with ureteral stone (59%), 26 cases with vesical stone (9.5%), and 12 cases with urethral stone (4.5%). 4. The ratio of the right to the left of the upper urinary tract stones was 120:116. 5. The most favored predilection of the ureteral stones was lower 1/3 of the ureter in 62.8% of the ureteral stones. 6. The size and weight of the largest number of the urinary stones were below 1.0cm in length (59.7%) and below 0.5gm (38.7%). 7. The clinical symptoms of upper urinary tract stones were flank pain in 90%, gross hematuria in 19%, nausea and vomiting in 9% and frequency in 7%, Those of lower urinary tract stones were painful urination in 79%, sudden stoppage in 49%, frequency in 44% and gross hematuria in 42%. 8. The combined diseases were urethral stricture in 8 cases, B.P.H. in 7 cases, tuberculosis of genitourinary tract in 6 cases, neurogenic bladder in 5 cases, and lower ureteral stricture in 5 cases. 9. Treatment consisted of surgical intervention in 64.5%, instrumental manipulation in 19%, conservative treatment in 13.2% and untreated cases in 3.3%. 10. The largest number of the urinary stones on chemical components was of mixed composition of calcium phosphate and calcium oxalate.

Ureteroneocystostomy may be used in the cases of the vesicoureteral reflux, reteral stricture, ectopic ureteral orifice, ureterovaginal fistula and damage on the lower part of ureter during operation. 0nce ureteroneocystostomy is decided on every effort should be made to perform an antireflux procedure. The results of ureteroneocystostomy have improved consistently during last 20 years, but cases of reflux and postoperative ureterovesical obstruction are still encountered. A clinical study was made on 8 cases who had been performed ureteroneocystostomy at the Department of Urology, Jeonbug National University, Medical School from January 1978 to February 1980. The results were as follows` 1. The age of the patients ranged from 14 to 56 years, most common in fifth decade. The sex ratio was 3:1, with female 6 and male 2. 2. Underlying diseases for ureteroneocystostomy were ureteral stricture, megaloureter, ectopic ureteral orifice and vesicoureteral reflux. 3. 3 Ureters were performed with the method of paquin procedure, 2 ureters with the combination of paquin with Psoas-bladder hitch procedure, one ureter with the combination of Boari flap with Psoas-bladder hitch procedure, one ureter with Politano-Leadbetter procedure and one ureter with Lich procedure 4. Relatively good results of ureteral reimplantation were obtained in distal ureteral stricture, ectopic ureteral orifice and vesicoureteral reflux, except one case of megaloureter in which nephroureterectomy was performed later due to adynamic ureter 5. Complications were followed as persistent pyuria in one case and urine leakage in one case, and nephroureterectomy for adynamic ureter in one case.
