A clinical observation was made on 47 patients of renal staghorn calculi who were admitted to the Department of Urology, Chonnam University Medical School during the 6 years period from January, 1977 to December 1982. The following results were obtained. 1. There were 24 men and 23 women with a ratio of 1.04:1. The age of three-fourths patients of renal staghorn calculi ranged from 40 to 59 years, with peak age incidence in the fifth decade. 2. Prominent symptomatology was present in 44 patients and 3 patients were asymptomatic. In the symptomatic group flank pain was present in 40 cases, hematuria in 13 and recurrent urinary tract infection in 2. Of the asymptomatic patients 2 had significant bacteriuria and 1 had a nonfunctioning kidney on excretory urogram. 3. The calculus was unilateral in 40 patients (right side in 26 and left side in 14) and bilateral in 7. 4. The majority of the patients with renal staghorn calculi showed abnormal urine; finding and relatively well preserved renal function on excretory' urogram. 5. Preoperative urine cultures yielded l0s colonies per ml. organisms in 15 of the 31 patients (48.4%): Escherichia coli in 4, Proteus & Pseudomonas in 3 respectively, Staphylococcus & Enterobacter in 2 respectively and Klebsiella in 1. 6. A total of 47 operations was done in 47 patients. Of the 47 operations 4 were nephrectomies. Stones were removed in 43 patients (43 kidneys). Of the 43 kidneys extended pyelolithotomy was done for 22, pyelonephrolithotomy for 14, anatrophic nephrolithotomy for 4 and nephrolithotomy for 3. 7. A nephrostomy extended into the upper ureter was located in 18 patients (41.9%), There was no difference in duration of nephrostomy tube inlaying between extended pyelolithotomy and pyelonephrolithotomy. 8. Postoperative complications included remnant stone in 14patients(32.6%), hematuria in 11, pyelonephritis in 5 and urinary leakage from nephrostomy site more than 2 weeks in 3. 9. A chemical stone analysis, available in 36 patients, revealed apatite in 20, struvite in 12 and calcium oxalate in 4. A combination of struvite with apatite was present in 8 and of apatite with calcium oxalate in 7 of these 36 cases.

Nineteen patients of carcinoma of the prostate admitted to the Department of Urology, Chonnam University Medical School, between 1977 and 1981 were reviewed linically. The following results were obtained. 1. The average age of the patients was 68.6 years, with a range of 25 to 85 years. 2. The average duration from onset of the symptoms to admission was 8 months, with a range of 8 days to 4 years. The presenting symptoms were of prostatic obstruction in 17 cages (89.5%), gross hematuria in 3 cases (15.8%) and bone pain in 3 cases (15.8%). 3. Serum acid phosphatase level was elevated in 7 of 19 patients, 5 of whom had distant metastasis. Serum alkaline phosphatase level was elevated in 5 of 19 patients, 2 of whom had osteoblastic bony metastasis. 4. Biopsy of the prostate was performed by transrectal needle biopsy in 8 cases, transperineal needle biopsy in 2 cases and transurethral resection in 3 cages. All cases were revealed adenocarcinoma of the prostate. In 6 cases adenocarcinoma of the prostate was found within the hyperplastic benign prostatic lobes. 5. Orchiectomy was done in 5 cases and endocrine therapy was done in 13 cases. 6. Follow-up studies were performed clinically in 11 cages ranging in duration from 4 months to 42 months. During this period 3 patients died in 10 months, 11 months and 24 months after operation, respectively.

Digital subtraction angiography(DSA) was made in 72 patients at department of radiology, Seoul National University hospital from February 1982 to January 1983 with our system, SRM-II, developed by cooperation of department of medical engineering, Seoul National University Hospital. The results were as follows; 1. In the total 72 cases, vascular disease was 28 cases in which aortic disease including Takayasu's aortitis was 18 cases. Others were vascular tumors in 32 cases and various conditions such as renal donor and artificial arteriovenous shunt. 2. Extent of the lesion was well delineated especially in aortic disease in cluding 8 cases of Takayasu's aortitis, 6 cases of aortic aneurysm and 2 cases of Behcet's syndrome. 3. DSA can be done to outpatient without admission because of its simplicity and non-invasiveness. DSA is useful especially in the evaluation and follow-up of vascular disease and the diagnostic value is expected to grow continuously according to the renewal of system.

Microform cleft lip is a mild form of incomplete cleft lip, also known as a minimal occult, abortive, forme fruste cleft lip. However, it has no definition and few methods have been reported for its correction. A microform cleft lip is characterized as the incomplete union of the superficial portion of the orbicularis oris muscle. It is more prominent during facial expression than in a resting state. We confined microform cleft lip in our study to the absence of philtral skin change and a contracted position on the top of cupid's bow. During the past 5 years, 17 patients of microform cleft lip were operated on. We corrected the defect of the upper vermilion border and nostril sill with minimal incision, and repaired the underlying lip musculature in superficial discontinuity. Reduction of the widened alar base was performed. Deformed alar cartilage was dissected via rim incision, and suspended in a medial and upper direction with pull-out sutures. The most important thing is precise repair of the superficial portion of the separated orbicularis oris muscle via minimal incision, and it is best to operate after 1-year of age for accurate repair. The results were satisfactory and the parents were also satisfied. The advantages of this procedure are as follows: 1. Less visible, minimal scar on upper lip 2. Simultaneous correction of vermillion notching, deformed cupid's bow and nasal deformity. 3. Eversion of philtral ridge due to tenting effect of horizontal mattress suture 4. Philtral elongation effect by reduction of alar base and Z-plasty of cupid's bow.

Recently, technical developments in digital electronics and imge intensifier have improved the electronicrecording and processing of images. Both departments of radiology and of medical engineering of Seoul National Univeristy Hospital jointly developed idgital subtraction angiography system(SRM-I) and performed DSA in patients. The system was composed of angiography equipments, computer, video image storage and logarithmic amplifier. Fluoroscopic images were taken before and after 40-60 ml of contrast media were intravenously injected with speedfo 12-15 ml/sec. The images were recorded by V.T.R. with normal speed. The recorded images were processed with digitization, amplification, sutraction, enhancement, position manipulation and image smoothing. Arteriography of neck vessels, abdominal aorta and its branches and extremities were performed successfully by above mentioned methods in 20 cases and results were reviewed.

To differentiate amebic and pyogenic liver abscesses, sonography(US) and CT findings of 21 amebic and 22 pyogenic liver abscesses were reviewed retrospectively. US was performed in all cases and CT in 15 cases of each group. Eleven cases of amebic abscesses had well defined margin which was observed in 10 cases of pyogenic abscessed. Amebic abscesses showed hyperechoic wall in 7 cases and calcification in 4 cases. Ten cases of pyogenic abscesses had mearby intrahepatic duct dilatation which was observed in 2 cases of amebic abscesses. Pneumobilia was seen in 6 cases of pyogenic abscesses. US findings of clear margin and hyperechoic wall, and CT findings of intrahepatic duct dilatation, pneumobilia, and calcification were helpful in differentation of amebic pyogenic liver abscesses.

Jensen procedures with medial rectus recession were performed on 13 eyes of 10 patients with lateral rectus palsy caused by trauma. The cases were reviewed retrospectively to assess efficacy of the procedure and long-term stability. After the average 10.2 months of follow-up period, the 7 patients on whom unilateral Jensen procedures and medial rectus muscle recession were performed improved an average of 45.0 delta, and the 3 patients who underwent bilateral Jensen procedures and medial rectus muscle recession improved an average of 82.3 delta. Preoperatively, 12 eyses demonstrated abduction of -4, and 1 eye demonstrated abduction of -1. Postoperatively, abductions of eyes are as follows: 3 eyes -4, 5 eyes -3, 3 eyes -2, and 2 eyes -1. 10 eyes (76.9%) showed improved abduction of lateral rectus muscle, but 3 eyes(23.1%) were not changed. 4 patients(40.0%) acquired a functional area of diplopia free vision, but 6 patients(60.0%) did not, 1 patient developed diplopia postoperatively. No significant cases of vertical deviation were created. One showed anterior segment ischemia, but recovered without complications. Based on these results, the Jensen procedure combined with medial rectus recession is effective in correcting palsies of the lateral rectus muscle that is not recovered.

Though intravenous digital subtraction angiography (IV DSA) has several advantages over conventionalangiography in diagnosis and follow up of various vascular disease, it also has several undesirable problems suchas large volume of the contrast medium and inferior image quality compared to conventional angiography. Sorecently intraarterial digital subtraction angiography (IA DSA) was introduced for better image quality usingsmall amount of contrast medium. The authours had good clinical results IA DSA which were made in 20 patients withour own system, SRM-II, developed by cooperation of Departements of Radiology and Medical engineering, Seoul.National University Hospital. Intraarterial digital substraction angiography was found to have several advantagesover conventional angiography: (a) small amount of contrast medium, (b) reduced need for selective arterialcatheterization,(c) lower film cost, (d) shortened examination time, (e) ability to obtain a “road map”, and (f)easier detection of contrast medium. Also IA DSA has several advantages over IV DSA : (a) less dependency oncardiac output, (b) far less vessel overlapping, (c) reduction in patient motion through less painful procedure byreduced volume of contrast media and shorter imaging time.
