PURPOSE: Caliceal diverticular calculi are mostly asymptomatic. In certain cases they may be associated with chronic or recurrent pain, recurrent urinary tract infections, progressive renal damage and hematur ia. The treatment of symptomatic caliceal diverticular calculi has evolved from open surgery to less invasive procedures, such as extracorporeal shock wave lithotripsy (SWL), percutaneous techniques, retrograde ureteroscopy and laparoscopy, but it remains controversial. Percutaneous techniques are frequently used to address the diverticular stone burden, to fulgurate the diverticular wall, to dilated the diverticular neck and improve drainage. For this reason, we reviewed 33 patients with caliceal diverticular calculi to determine whether they could be treated successfully by percutaneous nephrolithotomy (PCNL) as the initial treatment. MATERIALS AND METHODS: A total of 33 patients with caliceal diverticular calculi underwent PCNL between February 1990 and February 2000. The majority of diverticula were located at the upper pole. Access was gained via a direct target puncture. After sequential dilatation of the tract, stones were removed and the diverticular wall was fulgurated. The diverticular neck was dilated with the Amplatz dilator upto 24-30 Fr. and a 20 Fr. nephrostomy catheter was placed. RESULTS: PCNL was performed successfully in 30 patients (90.9%), but puncture was failed in 3. Mean operative time was 105 minutes and mean hospital stay was 4.5 days. All patients who were treated successfully with PCNL became stone-free without any complication. Mean follow-up was 20 months (ranged from 1 to 108 months). Of the 26 patients with symptoms preoperatively, 25 patients were rendered symptom-free (96.2%). Twenty-four patients were assessed with an intravenous urogram at 1 or 3 months and 6, 12 months and there was no stone recurrence. The diverticula were obliterated or had improved drainage in 95.8% (23/24) of assessable cases. CONCLUSIONS: We confirmed that PCNL is a safe, less invasive and effective procedure and should be considered an acceptable form of primary management of patients with caliceal diverticular stone.

In vivo 31P NMR spectroscopic study of forearm wrist flexor muscles was performed in two groups of volunteers composed respectively of 6 sedentaries and 6 canoe athletes. A continuous isometric contraction of endurance exercises was adopted in oder to assess the endurance capacity and recovery potential of skeletal muscles. Differences in high energy phosphorus metabolism between the sedentaries and athletes were evaluated with and emphasis on the intracellular pH and Pi/PCr ratio as indicators of high energy phosphorus metabolism. There were no differences of baseline pH and Pi/PCr ratio between the two groups. The athletes sustained the exercise at more acidic intracellular pH and at a higher Pi/PCr ratio of intracellular conditions for an all-out than did the sedentaries. The recovery rate of pH showed no difference between the two groups. There was a tendency of faster recovery of Pi/PCr in athletes showing half recovery time(T1/2) of 39.0±3.0 seconds as compared to that of sedentaries (55.7±7.5 seconds). The recovery rate of Pi/PCr as a function of Pi/PCr ratio at a given period of time was significantly faster in athletes than in sedentaries (P<0.001). The correlation coefficient of the recovery rate of Pi/PCr against the Pi/PCr ratio was 0.985 and 0.914 respectively for the athletes and sedentaries. The pH and the Pi/PCR ratio at an all-out state can be used as indicators of endurance capacity and the recovery rate of Pi/PCr, as a reovery potential of skeletal muscles.

OBJECTIVE: The purpose of this study was to evaluate the MR spectrum and MR cholangiographic imaging findings of clonorchiasis. MATERIALS AND METHODS: We reviewed 26 patients with confirmed clonorchiasis by either stool tests (n=24) or surgery (n=2). MR imaging was performed on a 1.5 T system (GE Medical Systems, Milwaukee, WI) with a torso coil. Axial T1-and T2-weighted, gadolinium-enhanced dynamic images and MR cholangiography were obtained. Image analyses were used to identify abnormalities of the intrahepatic and extrahepatic bile ducts and the presence of hepatobiliary malignancy. All MR examinations were reviewed by the consensus of two abdominal radiologists. RESULT: Intrahepatic bile duct abnormalities were seen in 23 (89%) of the 26 patients. The most common finding was mild dilatation of the intrahepatic bile duct which was found in 21 (81%). "Too many intrahepatic ducts" were found in 16 (62%), wall enhancement and thickening in 21 (81%) and filling defects and ductal stricture in the intrahepatic bile duct in 6 (24%) and 3 (12%) patients, respectively. Extrahepatic ductal dilation was found in 5 (19%) and 9 (35%) revealed hepatobiliary malignancy. CONCLUSION: MR imaging revealed various findings of clonorchiasis, including dilatation, wall enhancement, stricture of the intrahepatic ducts and filling defect within the intrahepatic bile duct.

Percutaneous transluminal angioplasty(PTA) were performed in three patients with atherosclerotic stenosis of subclavian arteries. The arteries were successfully dilated without complications during the procedure. All patients were asymptomatic during follow-up periods ranging from eight months to fifteen months after PTA.

BACKGROUND: This study investigates the prevalence of human papillomavirus (HPV) 52 and 58 genotypes among women residing in Busan, and the expression of p16 and p53 proteins in cervical neoplasia with HPV 52 and 58 infections. METHODS: A total of three hundred fifteen cases were analyzed using the HPV DNA chip test for HPV genotypes, and of these, we retrospectively examined p16 and p53 expression in 62 cases of cervical tissues infected with HPV 52 and 58 using immunohistochemistry. RESULTS: HPV 52 and 58 genotypes were identified in 62 (54.9%) out of 113 high-risk, HPV-infected cases. Of the cases examined, there were 19 single HPV 52 infections (16.8%), 23 single HPV 58 infections (20.4%), 4 multiple HPV 52 infections (3.5%), and 16 multiple HPV-58 infections (14.2%). Immunoreactivity of p16 and p53 was observed in 41 (66.1%) and 23 (37.1%) of the 62 cases of cervical neoplasia infected with HPV 52 and 58 genotypes, respectively. CONCLUSIONS: This study demonstrates a high prevalence of HPV 52 and 58 genotypes, in addition to HPV 16, among high-risk strains of cervical neoplasia in Korea. These findings suggest that development of more vaccines would be beneficial for the prevention of the various HPV genotypes.
