PURPOSE: To determine, when extracorporeal shockwave lithotripsy is contraindicated, the usefulness and safety of percutaneous management in the removal from the upper urinary tract of foreign bodies and calculi, or small remnants of these, retained affer percutaneous nephrolithotomy. MATERIALS AND METHODS: Between January 1996 and May 2001, we attempted to retrieve foreign bodies or calculi from the upper urinary tract of 20 patients, using various percutaneous techniques. There were eleven foreign bodies, namely fragmented nephrostomy catheters (n=2), migrated ureteric stents inaccessible to retrograde ureteroscopic management (n=8), and one metallic radiopaque marker which was separated from the pusher of the internal ureteral stent. Nine urinary tract calculi were present. These ranged in radiographically measured size from 4 to 8 mm in their largest diameter, and were found in the renal pelvis or calyx (n=5) and ureter (n=4). After percutaneous nephrostomy, all procedures involved the use of a 7-F to 14-F sheath, inserted under fluoroscopic guidance. Devices used for the retrieval of these objects include a stone basket retriever, loop snare, grasping forceps, and balloon catheter. RESULTS: In all cases except one, it was possible to retrieve calculi or other items from the upper urinary tract. No surgical procedure was required and no significant complications were encountered in any of the cases during or after the procedures. CONCLUSION: The percutaneous technique can be useful and safe in the management of foreign bodies or calculi present in the upper urinary tract.

This study was conducted to compare the date on knowledge, attitude and motivation toward blood donation between donors and non-donors. The study population included 622 donors and 322 non-donors who visited the mobile blood donation car of Taegu Red Cross Blood Center and participated the group appointed blood donation campaign managed by the center from March 1 to March 31, 1989. The donors and non-donors were questioned above mentioned items with a formulated questionnaire. Among the general characteristics of the subjects in the study, male predominance (84.1% in donors and 73.6% in non-donors) in young age group (16-24 years) was the outstanding feature. As a medium of information about blood donation, “television” was playing a dominant role (donors; 75.2%, non-donors; 78.9%), while “magazine” played more important roles among donors. Of the donors, 70.6% and of the non-donors, 58.1 replied that they had ever been induced to donate blood (p<0.01). Major inducers were friend and personnel of mobile blood donation vehicle. On the measuring of knowledge level, the average rates of correct answer was higher in donors (62.6%) than in non-donors (54.1%) (p<0.01). Higher the education level was presented, higher the knowledge level (p<0.05). There have been noticeable difference between donors and non-donors in blood replying the questionnaire set to measure their attitude toward blood donation, especially in the items such as “impression toward blood”, “selection of transfusion blood source” and “view on the situation of blood shortage.” The major motivation toward blood donation of the groups were “possible future need” and “altruism or humanitarian interest”. The major reasons for not donation blood in both groups were “fear of the needle” and “dread to visit to mobile car or center”.

Birth brachial plexus palsy (BBPP) is usually caused by plexus traction during difficult delivery. Although the possibility of complete recovery is relatively high, 5% to 25% of BBPP cases result in prolonged and persistent disability. In particular, muscle imbalance and co-contraction around the shoulder and elbow cause abnormal motor performance, osseous deformities, and joint contracture. Physical and occupational therapies have most commonly been used, but these conventional therapeutic strategies have often been inadequate, in managing the residual muscle imbalance and muscle co-contraction. Therefore, we attempted to improve the functional movements, by using botulinum toxin type A, to reduce the abnormal co-contraction of the antagonist muscles.

The Harris line (HL), caused by bone-growth arrest and manifesting on X-rays as a radiopaque transverse line in the metaphysis of the long bones, is an indicator reflecting stress conditions such as disease or malnutrition. HL frequency has been assumed to differ between pre-modern and modern societies, as reflective of increased caloric intake and overall nutritional improvements attendant on industrialization. To determine if such a change occurred in Korea, in the present study we compared the respective HL statuses in medieval Joseon and modern Korean population samples. HLs were found in 39.4% (28/71) of the Joseon Koreans. Whereas only 27.5% (11/40) of the males showed an HL, fully 54.8% (17/31) of the females exhibited it. Notably, HLs were observed in only 16.4% (35/213) of the modern Koreans; more remarkably still, the HL rate was almost the same between the sexes, 16.7% (20/120) for the males and 16.1% (15/93) for the females. The HL frequency was much higher in the Joseon Koreans than in their modern counterparts, reflecting the improvement of nutritional status that had been achieved in the course of South Korea's modernization. This HL-frequency decrease was much more obvious in the female populations. The higher HL frequency among the Joseon females might reflect the relatively poor nutritional condition of females in pre-modern Korean society.

PURPOSE: A laparoscopic appendectomy (LA) is becoming popular for the treatment of acute and perforated appendicitis. Since it was first described, the LA has been modified many times. We present the result for a new technique of LA, in which the LA is conducted through a single umbilical incision without exteriorizing the appendix to perform the operation. METHODS: A single incision laparoscopic appendectomy was attempted in 25 patients (17 men, 8 women). Under general anesthesia, a wound retractor was inserted through the umbilicus. The appendix was grasped and dissected from surrounding tissues with a single flexible dissector or grasper. After mesenteric dissection with ultrasonic shear, the base of the appendix was ligated with an Endoloop. The appendix was withdrawn into the wound protector and extracted from the abdomen. RESULTS: A single incision laparoscopic appendectomy was completed in 25 patients. No major intraoperative or postoperative complications were encountered. The average duration of the procedure was 50.3+/-21.3 min. The average hospital stay was 4.1+/-2.4 days. CONCLUSION: This new technique, a single incision laparoscopic appendectomy, further improves the minimal invasiveness of a LA because a single incision is used. This procedure is a safe, very minimally invasive procedure with excellent cosmetic results.

PURPOSE: To investigate the problems of the Hanaro stent (Solco Intermed, Seoul, Korea) when used in the palliative treatment of patients with inoperable malignant biliary obstruction. MATERIALS AND METHODS: Between January 2000 and May 2001, the treatment of 46 patients with malignant biliary obstruction involved percutaneous placement of the Hanaro stent. Five patients encountered problems during removal of the stent's introduction system. The causes of obstruction were pancreatic carcinoma (n=2), cholangiocarcinoma (n=2), and gastric carcinoma with biliary invasion (n=1). In one patient, percutaneous transhepatic cholangiography and stent insertion were performed as a one-step procedure, while the others underwent conventional percutaneous transhepatic biliary drainage for at least two days prior to stent insertion. A self-expandable Hanaro stent, 8-10 mm in deameter and 50-100 mm in lengh, and made from a strand of nitinol wire, was used in all cases. RESULTS: Among the five patients who encountered problems, breakage of the olive tip occourred in three, upward displacement of the stent in two, and improper expansion of the distal portion of the stent, unrelated with the obstruction site, in one. The broken olive tip was pushed to the duodenum in two cases and to the peripheral intrahepatic duct in one. Where the stent migrated during withdrawal of its introduction system, an additional stent was inserted. In one case, the migrated stent was positioned near the liver capsule and the drainage catheter could not be removed. CONCLUSION: Although the number of patients in this study was limited, some difficulties were encountered in withdrawing the stent's introduction system. To prevent the occurrence of this unusual complication, the stent should be appropriately expansile, and shape in the olive tip shoud be considered.

Autosomal dominant polycystic kidney disease (ADPKD) is a common genetic disorder characterized by innumerable bilateral renal cysts. It has an prevalence rate of one in 200~1,000 individuals and is a relatively common cause of renal failure. As renal function deteriorates, overall renal size usually diminish in patients with chronic renal failure. However, renal size of patients with ADPKD usually continues to increase, even after the initiation of dialysis therapy, because numerous cysts replace renal mass. Attempted methods to reduce the size of enlarged kidneys have included needle aspiration and sclerotherapy, cyst decompression surgery, laparoscopic and surgical nephrectomy. The outcome of these therapy frequently has been suboptimal, and there is a need to develop a more effective therapy. We report a case of renal arterial embolization using 99% ethanol and lipiodol mixture for ADPKD in a hemodialysis pathient, which has not been previously reported.
