A clinical observation was made on 112 cases of hypospadias which were treated at the Department of Urology, Seoul National University Hospital during the period June 1977 through May 1982. The results were as follows: 1. The ages were distributed from 7 months to 31 years and most of the cases (64.3%) was treated in the age group of less than 7 years. 2. Most of the types of hypospadias was penoscrotal type (43.8%). 3. Cryptorchism was the most frequent associated anomalies with 21 cases (18.8%). 4. The complication rate of other anomalies was greatest in the perineal type (81.8%). 5. Success rate of one-stage urethroplasty was 52.9%. 6. In two-stage operation, the first stage operation of 97 cases was successful except one of incomplete chordee release and the success rate of Thiersch-Duplay and Johanson second stage urethroplasty was 44.4% and 66.7% respectively. 7. As the urethral stent was used in the urethroplasty, the success rate of use of silastic tube was better than red rubber and feeding tube.

Cystic lesions of the kidney were experimentally induced by a single injection of methylprednisolone acetate(MPA), 20mg/kg, and morphometric analysis and ultrastructural observations by means of trans. mission and scanning electron microscopes were carried out after 1,2,3 and 4 weeks to clarify the nature of the cysts and their Histogenesis. l. The cystic lesions developed by administration of MPA were categorized into tubular and glomerular cysts ; the former underwent gradual regression of its number after the first week together with reduction of its ratio to the renal volume, whereas the latter progressed. 2. The subcapsular cystic structures(average diameter of ll0um) was originated from the dilated collecting tubules by 180 degree rotation in regard with abnormality in maturation process of nephorgenic activity. 3. Abnormalities of both proximal and distal convoluted tubules were reflected by increases of tubular diameter(l.54~3.55 times) and nuclear density(1.77~l.72 times), representing a compensatory dilatation of tubular lumen in association with shortening of tubular length. 4.Convolution of tubules was reduced and parallel to the shortening of tubular length. The above morphometric and ultrastructural features support that cystic lesion in the subcapsular portion induced by administration of MPA arises from the subcapsular collecting tubules by maturation arrest of nephorgenic activity.

We have experienced three cases of extrarnsmmary Pagets disease. The first case was a 77-year-old female who showed 8x10cm sized, erythematous plaque on the suprspubic area of one year's duration. The second case was a 60-year-old male who showed erythematous, oozing, crusted, well circumscribed patches on the right scrotum and the pubic area of 8 years' duration. Third case was a 79-year-old male who showed erythernstous to gray, eczemstoid plaques with marginal elevation on the right side of the scrotum, penile root and pubic area of 3 years duration. On histologic exarnination, the third case showed swest gland adenocarcinoma in the dermis.

Records of 15 patients of primary ureteral tumor which were managed in Seoul National University Hospital during 13.5 years period from January 1971 to June 1983. 1. Primary ureteral tumor comprised of 2% of all urothelial tumors and the ratio of bladder:pelvis:ureter was 40:2:1. 2. There were 11men and 4 women (ratio of 3:1) with a mean age of 62.7 years. 3. The most frequent site of ureteral tumor was the lower one third of the ureter (53%). 4. Most frequent presentation was gross hematuria. usually intermittent and painless (100%). 5. Non-visualization of the kidney was the most prevalent finding (73%) on excretory urogram. Retrograde pyelogram was necessary in 11 patients whose findings of IVP was insufficient for diagnosis, and these procedures provided definite diagnosis in 9 of 11 patients. 6. Urine cytology was positive in 4 of 13 patients. 7. Cystoscopy was performed in all patients and which revealed concomitant bladder tumor in3 patients and tumor in ureteral orifice in 2 patients. 8. There was close correlation between the grade of cellular anaplasia and the degree of invasion. 9. There were 3 recurrences (50%) in the ureteral stump in 6 patients treated by nephrectomy and partial ureterectomy.

PURPOSE: Intravenous propofol anesthesia has been safely and effectively used in the ureteroscopic management of lower ureteral calculi. We investigated whether we can also use propofol anesthesia effectively for the treatment of middle and upper ureteral calculi. MATERIALS AND METHODS: We performed ureteroscopy with intravenous propofol anesthesia in 200 consecutive patients with ureteral calculi from July 1998 to December 2001. We divided them into 2 groups. Group 1 consisted of 59 patients, 48 men and 11 women, with upper and midureteral calculi, and group 2 consisted of 141 patients, 94 men and 47 women, with lower ureteral calculi. We compared safety, success rate, length of hospital stay and complication rate between the two groups. RESULTS: The overall success rate for ureteroscopy was 94.5% (189/200). Seven patients suffered perioperative complications, none of whom needed to change mode of anesthesia or remembered discomfort during the operation. In group 1, stone size, operation time and postoperative hospital stays were 7.5+/-3.2mm, 33.0+/-20.3 minutes and 1.9+/-1.0 days, respectively. The equivalent results were 6.2+/-2.9mm, 22.9+/-15.0 minutes and 1.4+/-0.9 days, respectively, in group 2. There were no significant differences in age, complication rate or success rate between the two groups. CONCLUSIONS: In patients with middle and upper ureteral calculi, ureteroscopic stone removal under intravenous propofol anesthesia can be performed safely and effectively without any significant increase in morbidity or patient discomfort.
