Purpose: There have only been a few reports concerning the treatment of choice for overactive bladder (OAB). The aim of this study was to assess the effect of functional magnetic stimulation(FMS) in patients with an overactive bladder. Materials and Methods: Among the demonstrable overactive bladder patients, 21 were selected. They were classified into neuropathic and idiopathic OAB according to their etiology. Voiding diary, quality of life(QOL) questionnaire and urodynamic studies were evaluated before treatment. The treatment was performed for 20 minutes, 2 times a week, for 6 weeks. All of the evaluations were repeated immediately and 3 months after treatment. The treatment outcomes were evaluated for both the neuropathic and idiopathic groups. Results: The overall mean age was 44.0±18.6 years. After 6 weeks of treatment, the mean frequency in the idiopathic group significantly decreased from 13.0±2.3 to 9.7±2.1 times(p<0.05). The mean urgency episodes in the neuropathic and idiopathic groups decreased from 11.3±7.5 and 4.5±5.8 times to 8.5±6.2 and 3.0±4.3 times, respectively. Significant improvements were noted in the frequency, mean voided volume, maximal voided volume and QOL in the idiopathic group, which were maintained for 3 months(p<0.05). There were improvements in the symptoms and QOL in the neuropathic group also, but these were minimal. Conclusions: Our data suggest that the FMS therapy has, at least, a short-term effect on idiopathic OAB. To our knowledge this is the first report on FMS therapy for neuropathic OAB. Although its acute effect on neuropathic OAB was minimal, there was some improvement in the QOL. Therefore, in our opinion, further studies are needed to establish the long-term efficacy of FMS therapy in patients with symptoms of OAB. (Korean J Urol 2004;45:701-706)

유기 박막 트랜지스터 (Organic Thin film Transistors ; 이하 OTFT)는 1986년부터(1) 반도체 장치의 새로운 부류로 급속하게 발전해 오고 있다. 반도체 산업에 있어 이러한 유기물질의 큰 발전은 1947년에 있었던 최초의 inorganic FET (Field Effect Transistor) 탄생에 버금갈 만한 성과라고 여겨진다.(중략)

Ureteral injury is rare after blunt trauma, and especially in adults. This unusual scenario for ureteral injury typically occurs at the level of the ureteropelvic junction in children. Proximal and mid ureteral injuries are much less frequent and they are commonly associated with transverse process fracture. To our knowledge, the isolated avulsion of the ureter at this location is very rare. We experienced a longitudinal rupture of the right ureter about 3cm below the ureteropelvic junction in a 44-year-old male after a traffic accident. No other intraabdominal injuries were identified except for the multiple rib fracture. The ureteral injury was immediately diagnosed and repaired first. Intravenous urography was performed 12 weeks after surgery and it revealed normal ureteral patency without any sequelae. (Korean J Urol 2004;45:1285-1287)
