PURPOSE: To evaluate the usefullness of repeated alcohol sclerotherapy for two days through the percutaneous catheter in the treatment of renal cyst. MATERIALS AND METHODS: Repeated sclerotherapies using absolute ethanol(99.9%) were parformed on 20 renal cysts in 18 patients through the indwelling catheter. The cyst volume ranged from 50 ml to 1000ml(mean, 300ml). Under the ultrasound- or CT-guidance, 6F catheter was inserted into the cyst percutaneously. After aspirating the fluid in the cyst, absolute ethanol was injected. While maintaining the catheter for 16-20 hours, at least 3 times of sclerotherapies performed with total procedure time of 30-60 minutes. Follow-up sonography was performed to evaluate the recurrence or collapse of the cysts at 1 and 3 months after the procedure. RESULTS: Among 20 renal cysts, 2 cases were recurred on 1 month follow-up sonography(10%). However, the volumes of recurred cysts were decreased to 40% and 10%, respectively. There was no immediate or delayed complication after sclerotherapy. DISCUSSION: Repeated sclerotherapy for 2 days using absolute ethanol through the percutaneous catheter insertion is a useful method of treatment for renal cyst.

The epidermoid cyst of the testis is a rare benign lesion with a characteristic gross and microscopic appearances. This 25 year old male who had been previously diagnosed as Klinefelter's snydrome (47/XXY) had right orchiectomy due to hard testicular nodule for a presented malignant testicular tumor. Sectioning of the testis revealed a intraparenchy matous cystic lesion, 1.5 cm in diameter, filled with cheesy white material. Histologically, stratified squamous epithelium lined the cyst. The remaining testis showed advanced tubular sclerosis and Leydig cell hyperplasia. It is necessary to submit multiple sections to rule out other histologic elements in the cyst wall or the presence of a scar. Although epidermoid cyst occurring as a solitary testicullar nodule could be regarded as a stage in the development of a teratoma, they need to be distinguished from the complex differentiated teratomas because of a distinct difference in prognosis.

A clinical observation was made on 29 cases of bladder rupture who were admitted to the Department of Urology, In Je Medical College Paik Hospital in Pusan during the period from June, 1979 to August, 1983. The results are as followings; 1. Of 133 cases of genitourinary tract injury, bladder rupture were 29 cases (21.7%), there composed intraperitoneal bladder rupture 19 cases, extraperitoneal bladder rupture 10 cases. 2. The 29 cases Comprised 19 males and 10 females (male:female=l.9:1). The most prevalent age group of bladder rupture was 20 to 29 years, showing 13 cases of the total cases (44.8%). 3. The causes of bladder rupture were traffic accident observed in 11 cases (37.9%), direct blow 7 cases (24.1%), iatrogenic 4 cases (13.8%), stab wound 3 cases (10.3%) and spontaneous bladder rupture was seen in 1 case (3.5%). 4. The common symptoms and signs of bladder rupture were abdominal pain, lower abdominal distension and gross hematuria, so on. 5. The common associated injuries with bladder rupture were pelvic bone fracture 10 cases (34.5), Cerebral contusion 7 cases (24.1%), rib fracture 4 cases (13.8%), rupture of posterior urethra 3 cases (10.3%), so on. 6. The retrograde cystography was the most likely to accurately diagnose a ruptured bladder, but 1 case was revealed false negative cystograms because of the large hematoma within the pelvic cavity. 7. In all cases, immediate bladder repair and indwelling urethral catheter, with or without suprapubic cystostomy were performed. 8. We experienced postoperative complications such as, voiding difficulty, vesicocutaneous fistula and epididymo-orchitis, etc.

Taurodontism is an anomaly characterized by a long and broad pulpal cavity and consumed apical location of the furcation area. This study aimed to determine the prevalence of taurodontism in deciduous molars based on digital panoramic radiographs of children. The study was performed on a sample of panoramic radiographs taken from 2,473 Korean children who visited the department of pediatric dentistry, Yonsei University Dental Hospital between Nov. 2005 and Mar. 2018. Taurodontism was mainly categorized by Daito’s method. Using panoramic radiographs, taurodontism was also categorized into mesotaurodontism, hypotaurodontism, and hypertaurodontism. Mesotaurodontism was the most prevalent type. A total of 2,473 panoramic radiographs were evaluated. The prevalence of taurodontism was 5.7% in general, 51.5% in the left quadrant, 48.5% in the right quadrant, 6.3% in the maxilla, and 93.7% in the mandible. The distribution of taurodontism stratified by gender showed a higher prevalence in males. This is a comprehensive study on the prevalence of taurodontism in children using the largest sample size to date.

Tarsometatarsal injury has not been paid much attention due to it is unusual frequency. But the cases of tarsometatarsal injuries are on the increase in proportion to the increasing "high energy trauma injury" resulted from the traffic and industrial accidents. The purpose of this study is both assessing the relative effects among clinical results, final radiologic findings, treatment results and symtoms. In view of the results so far achieved from 20 cases of tarsometatarsal fracture dislocation which had been treated at Sung-Ae general hospital from January 1990 to December 1993, the results were as follows: 1. Thirteen cases were treated by open reduction and 3 cases were treated by closed reduction with smooth pins but no reduction loss were experienced. 2. Traumatic arthrosis could be observed in 14 cases but there were no influences on the functional end results. 3. Anatomical results correlated with pain. 4. Anatomical or neraly anatomical reduction was considered as most important factor of prognosis.
