Aims:u2002 We evaluated the association between HMGI(Y) expression and the detection of malignant cells by simple reverse transcriptase‐polymerase chain reaction (RT‐PCR) and correlated the level of HMGI(Y) expression and the clinicopathological data in gastric cancer.

Purpose The aim of this study was to evaluate the effect of desmopressin combined with anticholinergics on daytime frequency and urgency in female patients with overactive bladder (OAB). Materials and Methods We included 68 female patients with OAB. Patients were randomly assigned to receive 5 mg of solifenacin (group I) or 5 mg of solifenacin and 0.2 mg of desmopressin (group II) for 2 weeks. A pre/post-treatment 3-day voiding diary and the Urinary Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7) were used to assess changes in voiding symptoms and quality of life (QoL); results were compared between the two groups. Results Groups I and II included 31 and 37 patients, respectively. Time to first void was 12 min later in group II (105 min vs. 117 min), but this difference was not statistically significant. However, time to the second and third voids (203 min vs. 255 min, 312 min vs. 368 min) and the first urgency episode (212 min vs. 255 min) were significantly longer in group II. Compared with group I, patients in group II showed significant improvement in QoL scores. When improvement after treatment was defined as increase in time to first void of greater than 10% after 2 weeks of treatment, desmopressin with anticholinergics was more effective in patients over the age of 65 years and with more than 150 ml of voided volume. Conclusions Desmopressin combined with anticholinergics was more effective than anticholinergics only in the treatment of female patients with OAB.

The aim of this study is to evaluate whether polylactic acid (PLA) microspheres and adipose-derived stromal vascular fraction (SVF) cells have appropriate properties as an injectable bulking agent in urologic field. Forty male Sprague-Dawley rats (2-week-old) were randomized into two groups. A total of 0.05 mL of PLA microsphere suspension and 0.05 mL of PLA microsphere suspension mixed with PKH26-labeled SVF cells were injected into bladder wall in group I and group II, respectively. At 2, 8, 16, and 24 weeks of PLA microspheres injection, the volumes of implants were measured and bladder tissues including implants were analyzed and compared grossly and histologically between groups. The distant organs were examined histologically to determine migration of PLA microspheres. At 24 weeks of implantation, 65-70% of injected volume was maintained and there was no significant difference between groups. In histological analyses, injected PLA microspheres were localized in muscular layer of bladder without infiltration into adjacent layer. From 8 to 16 weeks of injection, hybrid tissues contained collagen and actin were observed between PLA microspheres and these findings were more clear in group II. PHK26-labeled SVF cells were identified by fluorescence microscopy at all time points. There was no migration of PLA microspheres to other organs and no abnormality in weight gain and hematologic values. These results suggest the possibility of PLA microspheres as a potentially useful bulking agent in urologic field. And further investigation is needed to know synergic effect of SVF cells.

Purpose With the improved surgical techniques and immunosuppression available today, conventional prognostic factors have taken on less significance. Accordingly, the native renal function of the donor is thought to be more important. Thus, we analyzed the prognostic significance of the donors renal function as assessed by 24-hour urine creatinine clearance on kidney graft survival for 10 years after living kidney transplantation. Materials and Methods From January 1998 to July 2000, 71 living kidney transplantations were performed at a single institution. From among these, 68 recipients were followed for more than 6 months and were included in the present analysis. We analyzed kidney graft survival according to clinical parameters of the donor and the recipient. Results Mean follow-up duration of recipients after living kidney transplantation was 115.0±39.4 months (range, 10 to 157 months), and 31 recipients (45.6%) experienced kidney graft loss during this time period. Estimated mean kidney graft survival time was 131.8±6.2 months, and 5-year and 10-year kidney graft survival rates were estimated as 88.2% and 61.0%, respectively. Donors mean 24-hour urine creatinine clearance (Ccr) before kidney transplantation was 122.8±21.2 ml/min/1.73 m2 (range, 70.1 to 186.6 ml/min/1.73 m2). The 10-year kidney graft survival rates for cases stratified by a donors Ccr lower and higher than 120 ml/min/1.73 m2 were 39.0% and 67.2%, respectively (p=0.005). In univariate and multivariate analysis, donors Ccr was retained as an independent prognostic factor of kidney graft survival (p=0.001 and 0.005, respectively). Conclusions Donors 24-hour urine Ccr before living kidney transplantation was an independent prognostic factor of kidney graft survival. Therefore, it should be considered before living kidney transplantation.

bothersome of all benign prostatic hyperplasia(BPH) symptoms. Nocturia with BPH is generally thought to be closely associated with change of detrusor receptor and infection secondary to bladder outlet obstruction. 1) However, age-associated physiological changes in bladder function and concurrent disease, for example, congestive heart failure, cause nocturia in elderly. Therefore, in BPH with nocturia, evaluation for etiology of nocturia is important for proper control of nocturia permanently and this study was performed to investigate the underlying etiology of nocturia. Materials and Methods:The twenty-seven BPH patients who complained more than three times of nocturia were included in this study. Evaluation included voiding diary for 24 hour, and urodynamic study. Based on diary and urodynamic study, functional bladder capacity was determined and etiology of nocturia was classified into one

Bacillus Calmette-Guerin(BCG) has been widely used for the prophylaxis of superficial bladder tumor recurrence and for the treatment of bladder carcinoma in situ. More than 95% of patients who receive BCG instillation tolerate the treatment well and side reactions have been reported in less than 5% of patients. Most side effects are minor and self-limiting. However, a rare occurrence of severe systemic reactions have been reported. Among the severe systemic reactions, hypersensitivity pneumonitis should be considered in patients with pneumonic complications after BCG instillation in cases where the culture for mycobacteria is negative in the sputwn, brochoalveolar lavage and blood specimen. In addition, a fiberoptic bronchoscopy with transbronchial lung biopsy demonstrates a fibrosis of the alveolar septums, where there is and an increased lymphocyte count with out tuberculous inflammatory changes, the and CD4 : CD8 ratio is increased and no symptomatic response to antituberculosis chemotherapy is observed. Here we report a 68 years old man with interstitial pneumonitis following intravesical BCG instillation.
