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%.

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.

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 clinical observation of ureterolithotomy without closure of the ureter was done in 57 patients during the period from Sep., 1970 to Aug., 1974 in the Department of Urology. Daegu Presbyterian Medical Center. The results are as follows. 1) Incidence of ureteral stones is higher in male than in female, ratio M:F=1.6:1 and the most common age group is from 30 to 39 years with 54.3% of the total cases. 2) Locational distribution of ureteral stone; 27 cases in the upper, 5 in the middle and 25 in the lower ureter. 3) The size of ureteral stone is from 0.3 x O.4cm to 1.4x 2.2cm. The average size is 0.48x 0.80cm. 4) The druation of post-operative urine drainage was 7.4 days in the upper ureter, 4.4 days in the mid ureter and 7.6 days in the lower ureter. 5) Post-operative complications: Persistent urine leakage requiring retrograde catheterization; 1 case. Pyelonephritis : 2 cases. 6) Change of post-operative I. V. P. findings; Improved in 50 cases, not changed in 3 cases and deteriorated in 4 cases. 7) Post operative hospital stay; 10. 5 days in the upper, 8.4 days in the mid and 11.3 days in the lower ureter.

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.

Xanthogranulomatous pyelonephritis is a distinct type of renal infection characterized by massive enlargement., lithiasis, hydronephrosis and the appearance of yellow lobulated masses in the pelvis and calyces grossly, and by multinucleated giant cells and foam cells microscopically. Also this is a rare disease, which may be confused clinically, grossly and microscopically with other renal diseases such as renal cell carcinoma, renal tuberculosis and malakoplakia. A case of xanthogranulomatous pyelonephritis in a 53 years-old female is presented with a brief review of the literatures.

Purpose: The ideal neurourophysiologic investigatory technique would objectively and quantitatively evaluate functional status of all parts of the neurologic network involved in obtaining and maintaining penile erection. We assessed electrical activity of the corpus cavernous smooth muscle in normal and neurogenic erectile dysfunction men using SPACE. Material and Methods: A total of 39 normal subjects and 40 neurogenic erectile dysfunction patients underwent single potential analysis of cavernous electricity(SPACE) with a 2-channel EMG amplifier and surface electrodes. The electrical potentials were processed with the cut off frequencies at 0.3 - 32 Hz, a paper speed of 0.5cm/sec, and a range of amplitude of 0.5mV. Results: In 35 of 39 normal subjects(89.7%) and 5 of 10 incomplete suprasacral spinal cord injury patients, similar single potentials of uniform shape were recorded. In patients with peripheral autonomic denervation, irregular shape potentials with higher frequency and lower amplitude were found. In 3 of 5 patients with long standing diabetes(over 15 years), SPACE shows electrical silence. Conclusion: These results suggest that SPACE test is a useful noninvasive and reproducible method for evaluating cavernous innervation in erectile dysfunction. Furthermore, the single potential means intact cavernous innervation.

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.
