The discovery of an abdominal mass in a child usually presents a challenging problem in diagnosis and therapy to the pediatrician, surgeon and urologist. In abdominal masses, the fact that the kidney is the organ which singly produced more palpable masses than any other abdominal organ or even tract was accepted universally and most frequent causes were hydronephrosis, cystic kidney and Wilms` tumor in foreign literatures. In recent retrospective study of 52 cases of palpable abdominal masses in Korean infants and children, we obtained results as follows: 1) The kidney is the most common cause of palpable abdominal mass(86.5%). 2) Of 45 cases of renal masses, hydronephrosis is the most common(60%). 3) Of 45 cases of renal masses, Wilms` tumor is common(37.8%) but cystic kidney is rare(2.2%). 4) The most common cause of solid abdominal mass is Wilms` tumor(74%). 5) The most common cause of hydronephrosis is congenital UPJ obstruction(70%). 6) Neuroblastoma is seldom encountered.

ESWL has been demonstrated to be a safe and efficacious means to treatment of urinary calculi. We report the results of 176 patients(203 cases) treated with EDAP LT-01 lithotriptor between January 24 1989 and August 24 1989. The patients were followed for over two months. The results were obtained as follows ; 1. The sex ratio was about 2.4: 1, 125(71.0%) in male and 51(29.0%) in female. The fifth decade(30.1%) was most, followed by fourth decade( 26.7 % ) and sixth decade(18.2%) 2. The stone location showed that kidney was 128 cases( 63.1% ) and ureter was 75 cases( 36.9%), The stone size showed that 94 cases(46.3%) in under 10mm, 75(36.9%) in 11-20mm and 34(16. 8%) in over 21mm. 3. The overall success rate(complete in 74.9% and partial in 23.6% ) was 98.5%. The complete success rate of 122 cases who treated with frequency of 10/sec. was 53.3 %, but 81 cases who treated with frequency of 5/sec. showed the complete success rate of 76.6%. 4. Adjunctive procedures after ESWL were performed 6(3%), including ureterolithotomy in 2(1.0%) and pyelolithotomy, PCNJ PCNL and URS in each 1 case(0.5% ). 5. Complications were showed that gross hematuria for over 1 day in 68.3%, nausea and vomiting in 26%, renal colic in 17.9% and ureteral obstruction in 8.9%. But, all patients re- covered with only conservative treatment except URS and PCN in each 1 case. 6. There were not statistically significant changes in level of BUN, Creatinine, SGOT, SGPT and Creatine phosphokinase, but S-amylase and LDH were significantlychanged(p <0.05).

During the period from March 1990 to November 1993, 22 children with diplaced supracondylar fracture of humerus were treated by closed reduction and percutaneous K-wire fixation at department of Orthopaedic surgery in Yeungnam University. All fracture were treated with closed reduction under the general anesthesia and percutaneous pinning. After the fracture was internally fixed, intraoperative anteroposterior reontgenograms of each distal humerus were compared. Only anatomical reduction ensured good result,, because the main cause of late cubitus varus was medial tilting of distal fragment. We could follow up 10 patients more than one year. By Flynn's criteria, satisfactory result were obtained in 9 of the 10. Unsatisfactory one had a limitation in flexion of elbow joint, but had no problem in cosmetic feature. In short term follow up of 7 patients, 5 patients had a satisfactory result, too. There were no neurovascular complication and hospitalization was shortened to 11.4 days. Closed reduction and percutaneous pinning provided stabillity, vascular safty, simplified management, reduced hospital stay. This is safe and reliable technique for obtaining and maintaining an exellent reduction.

Effects of various peripheral vasoconstrictors on isolated porcine basilar and posterior communicating arteries(BA and PCA) were investingated and effected of flunarizine on the contractile responses were compared with those of a vasodilator, nitroglycerin. KCl elicited dose-dependent contractions in BA and PCA. 50mM KCl-induced contraction was not affected by nitroglycerin but dose-dependently inhibited by nimodipin and flunarizine in both rings. Epinephrine produced contractile response of BA and PCA in a dose-dependent fashion, but norepinephrine or phenylephrine did not cause obvious contraction by itself. Norepinephrine and phenylephrine elicited dose-dependent contractions in both rings treated with 10 -6M propranolol and the epinephrine-induced contractions were potentiated by pretreatment with propranolol, 5-hydroxytryptamine and histamine contracted BA and PCA in a dose-dependent manner and the contraction of PCA was more prominent than that of BA. In PCA rings, 10(-6)M 5-hydroxytryptamine and 10 -6M orepinephrine-induced contractions were not changed by nitroglycerin but inhibited by flunarizine in a dose-dependent manner. Small doses of flunarizine inhibited gradually both drug-induced contractions and large doses(3.5 x 10(-6) and 10(-6)M) steeply inhibit ed the contractions. Then the slopes of inhibitory curves in both cases were biphasic. Above results suggest that responsibility of catecholamine in porcine brain artery is more prominent in alpha-adrenoceptors than in beta-adrenoceptors, and inhibitory effect of flunarizine on brain artery results from inhibition of calcium influx through stimulated receptor-operated calcium channel(ROC) and potential-operated calcium channel(POC) .

Transcatheter arterial embolization has had an wide application in the control of bleeding of non-neoplastic origin. This approach has also been utilized in the treatment to tumors. Preoperative transcatheter embolization of renal neoplasm is helpful to the urologist, especially in large, hypervascular tumors. We experienced prenephrectomy therapeutic renal infarction by injecting Gel Foam and steel coils into the renal artery in 3 patients with renal tumor. This facilitated nephrectomy with decreased blood loss and we believe that this procedure contributes to the increase of survival rate of patients with renal tumor.

Retroperitoneal teratoma is a rare condition in only 10% of all retroperitoneal primary neoplasm and about 200 cases has been recorded since Morgagni`s first description in 1961. Recently we experienced a case of huge retroperitoneal teratoma(18kg), which was suspected by clinical investigation and confirmed by exploration and microscopic examination.
