Purpose:The aim of this study was to investigate the changes in and implications of preoperative and postoperative serum uric acid levels in patients with living donor nephrectomy.
Materials and Methods:We studied 207 patients between 1998 and 2007 at our hospital undergoing living-donor nephrectomy for kidney transplantation. The serum uric acid level and estimated glomerular filtration rate (eGFR) were measured preoperatively and at 1 year postoperatively. We also analyzed multiple independent variables such as age, sex, blood pressure, body mass index (BMI), serum total cholesterol, hemoglobin, hematocrit, total protein, albumin, calcium, and phosphorus. Results: The mean age of the study patients was 38.3±10.8 years. The mean serum uric acid concentration at 1 year after kidney donation was higher than preoperatively (5.05±1.39 mg/dl preoperatively vs. 5.85±1.14 mg/dl postoperatively) and was significantly greater in patients with hyperuricemia (uric acid≥6.8 mg/dl) than in patients without hyperuricemia (uric acid<6.8 mg/dl): 1.63±0.75 mg/dl vs. 0.69±0.66 mg/dl, respectively. The multivariate analysis showed that preoperative serum uric acid was the primary predictive factor of postoperative serum uric acid (r=1.136, p=0.001), and preoperative GFR was an independent secondary predictive factor (r=−0.004, p=0.047). The receiver operator characteristics (ROC) curves for the preoperative serum uric acid cutoff of 5.7 mg/dl showed the highest sensitivity and specificity of 96% and 86%, respectively. Conclusions: These results suggest that preoperative serum uric acid and GFR were important predictive factors of postoperative serum uric acid after living-donor nephrectomy. Therefore, in the selection and management of kidney donors, not only patients with a low GFR but also those with high uric acid (serum uric acid≥5.7 mg/dl) require careful observation before and after living-donor nephrectomy.

CoFeNi alloys are some of the most studied soft magnetic materials because of their superior properties over FeNi alloys as write head core materials in hard disk drives. Pulsed electrodeposition was shown to be an interesting approach to vary the crystalline structure of the fcc-bcc mixed phase CoFeNi and CoFeNiCu films without changing the composition and the grain size by using a single bath. The permeability of CoFeNiCu films plated from bath composition exceeded 4.6ϫ 10 6 . Coercivity H c was 20-73 A / m. The high saturation magnetic flux B s was 1.8 T. The soft magnetic CoFeNiCu film prepared satisfies all the requirements needed for the preparation of magnetic recording heads, as all magnetic properties were improved in this direction.
We herein report a case of ectopic prostate tissue involving the posterior wall of the bladder. A 33-year-old man was referred to our hospital because of a bladder tumor that was incidentally discovered on abdominal ultrasonography (US). US and computed tomography (CT) showed a 1.5x2.0cm sized tumor in the posterior wall of the bladder. Cystoscopic examination revealed a sessile tumor, covered with normal bladder mucosa in the posterior wall of the bladder. Transurethral resection of the bladder tumor was carried out and the origin of the tissue was confirmed by immunohistochemical staining for prostate specific antigen. The histopathological examination revealed benign prostate tissue that was situated ectopically.
