Takayasu's arteritis is an arteritis of undetermined etiology, which affects the aorta, the proximal portions of its major branches, and the pulmonary arteries, and causes coarctation, occlusion, or aneurysmal dilatation of the affected vessels. Authors has reported 9 cases in 1973, and another 24 cases in 1977. Thereafter, during next 4 years, authors experienced another 42 cases and obtained some additional results. The results are as follows: 1. Among 75 cases, 10 are male and 65 female patients with sex ratio of 1:6.5, and about 2/3 of total patients are under 30 years of age. 2. Headache, dizziness, absent or weak radial pulse and hypertension are the most common symptoms and signs. 3. Conventional chest roentgenography may be helpful but not specific in diagnosis of Takayasu's arteritis. 4. The aortographic findings are characteristic and pathognomonic in diagnosis of Takayasu's arteritis. In our series, the most common findings are stenosis or occlusion of subclavian artery, diffuse narrowing and aneurysmal dilatation of abdominal aorta and its branches, narrowing with irregular contour of descending thoracic aorta, and renal artery involvement. 5. Involvement of the aorta was classified as extensive type in 38 cases, descending thoracic and abdominal type in 22 cases and arch type in 15 cases. 6. As total aortography in cluding abdominal aorta uncovers evidence of unsuspected involvement of aorta and its branches, it is of paramount importance in the diagnosis of Takayasu's arteritis.

Currarino triadis a unique malformation complex of congenital caudal anormalies, including anorectal malformatio (anal stenosis, anal ectopis, imperforated anus), sacral bony abnormality (scimitar or crescentic bony defect, malsegmentation) and presacral mass (meningocele, teratoma, enteric cyst or any combination of these). This triad is familial in at least half of cases and the usual symptomatology is constipation due to anorectal stenosis. The embryogenesis is presumably due to abnormal separation of the neuroectoderm from the endoderm, so this triad is in the spectrum of the split notochord syndrome. We report a case of Currarino triad in 5-month-old female patient who had chronic constipation and abdominal distention with brief review of the related literatures.

Korean Journal of Urology 1991;32(3):444-451
Vasectomy has become a popular method for male sterilization in Korea and this, in turn, has been followed by an increase in the number of patients requesting vasectomy reversal. Recently, many authors have reported a high success rate of vasovasostomy using microsurgical techniques. However, a significant discrepancy persist between the patency and pregnancy rate despite improvements in surgical techniques. A total of 200 patients undergoing vasovasostomy from May 1983 to April 1990 were reviewed. Of these 200 patients, only 130 patients (98 patients by two-layer, 32 patients by modified two-layer technique) could be followed up and analyzed as to pregnancy rate related to age, vasal obstructive interval, gross appearance and sperm quality of the vas fluid, operative method, and presence or absence of sperm granuloma. Success rates were 90.3% for patency and 65.4% for pregnancy. With regard to factors influencing to operation, it seemed that the results were better when there was a shorter vasal obstructive interval, watery vas fluid, presence of normal morphologic sperm quality, presence of sperm granuloma, and when the operation was done using the two-layer technique. However, no statistically significant difference was found, except between the bilateral presence and absence of sperm granuloma at the vasectomy site. Thus it is suggested that the most important single factor influencing the success rate of vasovasostomy is a meticulous and skillful operative technique itself, althought other factors may affect the outcome. More effort and research are needed to find the factors affecting the success rate of vasovasostomy.

Percutaneous transhepatic biliary drainage was successfully made 20 times on 17 patients of obstructivejaundice for recent 1 year since June 1981 at department of radiology in Seoul National University Hospital. Thecauses of obstructive jaundice was CBD Ca in 13 cases, metastasis in 2 cases, pancreatic cancer in 1 case and CBDstone in 1 case. Percutaneous transhepatic biliary drainage is a relatively easy, safe and effective method whichcan be done after PTC by radiologist. It is expected that percutaneous transhepatic biliary drainage should bedone as an essential procedure for transient or permanent palliation of obstructive jaundice.

Catecholamine-induced cardiomyopathy associated with neuroblastoma is rarely reported. We report a case of catecholamine-induced cardiomyopathy associated with neuroblastoma in a 33-month-old female that was treated with extracorporeal membrane oxygenation (ECMO). She was tentatively diagnosed with acute myocarditis and presented with hypertension. Because of rapid patient deterioration despite pharmacological treatments, ECMO was applied. ECMO can be helpful in cases of catecholamine-induced cardiomyopathy associated with neuroblastoma.

Ureteroscopic removal of the stone is now popular for the management of the lower ureteral stone. A clinical study was performed on our 75 patients with lower ureteral stone treated with ureteroscopy. Of the 75 stone manipulations 62 (83%) were immediately successful and the final success rate including spontaneous delivery of stone or fragment after the procedure was 87 percents (65 cases). Of 57 smaller calculi than 1 cm (radiographic largest diameter) 50 (88%) were removed successfully. Mean duration of postoperative hospitalization was 5.6 days. There were no interrelations between the success rate and anesthetic methods. Significant complications during or after procedure were not identified. We conclude that ureteroscopic removal of stones under direct vision can be done safely and be the first choice of procedure for the lower ureteral stones.

We performed erotic stimulation that in 63 patients with erectile dysfunction in order to investigate erectile responses to visual sexual stimulation in patients with psychogenic and organic impotence and to elucidate valuable parameters for differential diagnosis between psychogenic and organic impotence. After the test using polygraph system and erotic film, subjective sexual drive in each patient was evaluated as grade I (poor), grade II (moderate), grade III (good). Following parameters were statistically analyzed : degree of maximal rigidity, degree of maximal tumescence, T -up phase (time taking place from the beginning of the erection to maximal level). The T-max phase (time taking place for the plateau phase of maximal erection). The results obtained were summarized as follows. Regardless of sexual drive of each patient, psychogenic impotence group showed better maximal rigidity and shorter T-up phase of rigidity than organic impotence group (p<0.05}. Of patients with psychogenic impotence, good sexual drive group showed better maximal rigidity and maximal tumescence than poor sexual drive group (p<0.06). Psychogenic impotence group showing good sexual drive revealed much better maximal rigidity and shorter T-up phase of rigidity than organic impotence group with same degree of sexual drive (p<0.05). These results indicate erotic stimulation test is highly valuable method for differential diagnosis between psychogenic and organic impotence, especially when the patient shows sexual drive in moderate or good degree. And it is suggested that maximal rigidigity and T-up phase of erection parameters in erotic stimulation test provide high validity for the differention.

It is well known that double contrast arthrography of the knee is a safe and technically simple procedure permitting accurate diagnosis of lesion of meniscus, especially tears. It has been utilized infrequently until recent years in our country. During the period of Oct. 1977 through Nov. 1978, double contrast arthrography of the knee had been performed in total of 52 cases with soft tissue injury of the knee and a total of 32 cases among them underwent the operation at the Armed Forces Taegu General Hospital. The arthrographic findings of the meniscus injury were presented and analyzed. The results were as follows: 1. Arthrography of the knee is a valuable diagnostic aid for meniscus injury. The diagnostic accuracy was 87.5 per cent for 32 cases. 2. In one case, tear of both menisci unsuspected on the basis of clinical examination were demonstrated one the arthrogram. 3. Arthrography revealed residual portion of the meniscus left after previous menisectomy in one patient. Reoperation resulted in cure. 4. Unnecessary surgery was reduced. 5. There were no complications of arthrography in thts series.

BACKGROUND: Understanding the differentiation and migrating character of the tympanic membrane, external auditory canal as well as cholesteatoma pathogenesis needs knowledge about epithelial generation center. OBJECTIVE: We investigated the distribution of the epithelial generation center in the tympanic membrane and external auditory canal using 5-bromo-2-deoxyuridine(BrdU) immunohistochemistry. MATERIALS AND METHODS: BrdU was injected into peritoneum of 10 Mongolian gerbils and gerbil's temporal bones were obtained and serial section was done. Anti-BrdU antibody immunohistochemical stain was done. RESULTS: The labeling index was highest at posterosuperior quadrant of pars tensa, higher at malleus handle attached area and annulus region. On pars flaccida, labeling index was high at entire area. The labeling index of deep meatal skin was higher than that of lateral meatal skin, especially near annulus area. According to results, epithelial generation centers are thought to be on pars flaccida, posterosuperior quadrant of pars tensa, malleus handle attached area and annulus region. CONCLUSION: These findings are similar to those of human tympanic membrane and external auditory canal, and gerbils can be used as a animal model for study of normal human tymapnic membrane, external auditory canal and cholesteatomas.
