A clinical study was made on the 28 cases underwent prostatectomy during the 5 year-period from 1964 to 1968. The results are summarized as follows: 1. The patient underwent prostatectomy revealed increasing tendency in incidence, residual urine in average and being usually in the age range between 60 and 70 years. 2. The degree of prostatic enlargement was mostly grade 11 on rectal palpation and the removed prostate was 49. 3gm. in average weight. 3. Blood loss attributable to the operative manipulation was 1143 cc. in average. The patients underwent prostatectomy were discharged on the average 21.3 days postoperatively in which postoperative indwelling catheter was left in place for 15.3 days in average. 4. Postoperatively the convalescence was uneventful and the residual urine was disappeared or decreased markedly. 5. In the patients underwent prostatectomy via retropubic approach operative blood loss was mild and postoperative duration of indwelling catheterization was short as compared to that via the suprapubic approach. 6. No serious complication other than epididymitis developed in a few patients was observed postoperatively. 7. Suprapubic prostatectomy was found to be suitable for the patient with marked prostatic enlargement while the retropubic one yielded less tissue damage and somewhat rapid postoperative convalescence as compared to the former.

Many kinds of operations have been devised to treat Kienböck's disease with variable results. But no one have mentioned about the advantage of early motion in distraction to prevent the fibro-osseous ankylosis and carpal collapse. Two cases with Kienböck's disease were treated by the complete excision of the lunate and replacement of it with pronator quadratus muscle pedicled rectangular bone graft. Once these procedures were accomplished, the distraction-motion devices were used to maintain the joint surfaces separated at predetermined distances while kinematically normal joint motion was gradually restored. Although the experience is limited to two cases, the final results seem to be very promising.

Paralytic hand is the ultimate result of permsnent damage of the central nervous system, failure of the functional repair of peripheral nerve injuries and extensive muscular or tendinous defect resulting in the impairment of hand function. There are a lot of controversies in the side of treatment methods in the paralytic hand, and it is very difficult to formulate the most adequate surgical reconstruction for a given pstient. At Depsrtment of Orthopedic Surgery, Seoul National University Hospital, 66 cases oi paralytic hands in 62 patients have been treated surgically with tendon transfers for 7 years from Jan, 1980 to Dec, 1986. 49 case in 46 patients were followed up for more than one year, and surgical method and its results were anslysed. They consist of CNS lesion (17), peripheral nerve lesion(23) and musulotenidinous defect(9). The methods of surgical reconstruction were opponenesplasty(12), standard set extensor reconstruction(9), Green and Bsnks FCU transfer(11), intrinsic reconstruction(7), pronator rerouting(7), adductorplasty (5) and so on. The mean follow-up was 2.2 years, and in 38 cases good or excellent results were obtained.

PURPOSE: We evaluated the importance of redistribution and 24 hour reinjection images in Tl-201 SPECT assessment of myocardial viability after acute myocardial infarction (AMI). MATERIALS AND METHODS: We performed dipyridamole stress-4 hour redistribution-24 hour reinjection Tl-201 SPECT in 43 patients with recent AMI (4-16 days). The myocardium was divided into 16 segments and perfusion grade was measured visually with 4 point score from 0 to 3 (absent uptake to normal uptake). A perfusion defect with stress score 2 was considered moderate. A defect was considered severe if the stress score was 0 or l (absent uptake or severe perfusion decrease). Moderate defect on stress image were considered viable and segments with severe defect were considered viable if they showed improvement of 1 score or more on redistribution or reinjection images. We compared the results of viability assess-ment in stress-redistribution and stress-reinjection images. RESULTS: On visual analysis, 344 of 688 segments (50%) had abnormal perfusion. Fifty two (15%) had moderate perfusion defects and 292 (85%) had severe perfusion defects on stress image. Of 292 severe stress defects, 53 were irreversible on redistribution and reversible on reinjection images, and 15 were reversible on redistribution and irreversible on reinjection images. Two hundred twenty four of 292 segments (76.7%) showed concordant results on stress-redistribution and stress-reinjection images. Therefore 24 hour reinjection image changed viability status from necrotic to viable in 53 segments of 292 severe stress defect (18%). However, myocardial viability was underestimated in only 5% (15/292) of severe defects by 24 hour reinjection. CONCLUSION: The 24 hour reinjection imaging is useful in the assessment of rnyocardial viability. It is more sensitive than 4 hour redistribution imaging. However, both redistribution and reinjection images are needed since they complement each other.

A new method of urinary diversion via Skinner`s modification of Koch continent ileal reservoir was tried. With this method continence with storage of urine under low pressure is well maintained so that no external applicances are necessary. Ileorenal reflux is also prevented with this nipple forming technique. From May l986 to September l986, 4 patients underwent urinary diversion that included creation of a modified Koch pouch by Skinner. Previous urinary diversion was by ureterocutaneous diversion in 1 patient. A total of 3 patients underwent radical cystectomies for bladder cancer In 1 patient, simultaneous urethrectomy was done because of carcinoma in situ in the urethra. There were no operative mortalities. All patients are continent and without reflux to the upper urinary tract. The volume capacity of pouch is more than 400ml. The pouch is emptied by self-catheterization every 4 to 6 hours during the day and once at night. Postoperative follow-up presently is short and it is impossible to check late complications. Although preliminary, this clinical trial suggests that the quality of life for patients can be improved markedly by the modified Koch continent ileal reservoir.

Hydroa vacciniforme is a very rare photosensitivity disorder. The primary skin lesion is a vesicle or bulla which then heals with vacciniform scarring. We report a case of hydroa vacciniforme recurred after 3 years period of quiescence in a 20 year-old man who had had history of the disease from the age of two. The duplication of the natural lesion, clinically and histologically, was successfully made by artificial UV-A irradiation on the patient's back.

A total of fifty three patients with posterior urethral strictures followed by pelvic bone fracture were managed by one-stage perineal repair at Pusan National University from Jan. 1985. to Jun 1992. End-to-end anastomosis was performed in all cases, but other procedures were added to accomplish tension-free anastomosis in 34 cases. These techniques, which included distal urethra mobilization, corporeal body separation and inferior pubectomy wore performed in a progressive manner as needed. Excellent results were achieved and success rate was 97.8 % of all cases. And we evaluate complications after such progressive maneuvers and the relationship between type of posterior urethral injury based on urethrography, the types of surgical procedure and the types of pelvic bone fractures. Additional procedure were attributed to severe initial type IV urethral injury, unstable pelvic bone fracture and complex urethral stricture. In spite of performing additional procedures, the incidence of impotence, restrictue and incontinence made no differences. Therefore, separation of corporeal bodies and inferior pubectomy are safe and efficient method to treat nearly almost cases of urethral strictures including complex urethral strictures.

Urine specimens were obtained from one hundred and thirty nine patients in-out-patient and in-patient service of B.N.U.H., Dept. of Urology, with the presumptive diagnosis of urinary tract infections or indwelling catheter. These specimens were processed by Triphenyltetrazolium Chloride test, quantitative test and identification of the organisms. The results were as follows: 1. Triphenyltetrazolium Chloride test was an easily performable and a fairmely accurate method for screening of urinary tract infections. 2. The urine specimens showed false negative reactions to triphenyltetrazoium Chloride in some cases with moderate (10(4) to 10(6) bacteria per milliliter) growth of bacteria or in the antibiotics used patients. 3. The incidence of urinary tract infections with gram negative bacilli are ninety-two percent. In their series, incidence of E. coli decreased and that of other gram negative bacilli increased such as Enterobacter, Proteus and Serratia, etc. This shift in the pathogen spectrum occurs mostly in the patients of complicated or lower urinary tract infections, in-patients, antibiotics used patients and the patients with indwelling catheter.

Korean Journal of Urology 1994;35(10):1151-1155
The congenital patent urachus is the failure of complete urachal lumen closure and results in a free communication between the bladder and the umbilicus. Embriologically the urachus represents the vestigial remnant of the allantois which, in the fetus, communicates with the cloaca. The first patient is a 6-day-old female infant, and she was transferred due to urine leakage from the reddish hen egg sized protruding mass on the umbilicus. The fistulogram showed a long fistulous tract which communicates with bladder and umbilicus. A complete resection of the patent urachus was done. The second patient is a 1-day-old male infant, and he was transferred for operation of omphalocele from local clinic. Urine leakage was detected from the urachus at operative field, and so complete resection of the urachus was performed, and the one stage repair was performed for treatment of mild intestinal herniation. Postoperative courses of the two cases were uneventful.
