Purpose: To prospectively investigated the symptom changes in women with an overactive bladder(OAB) after discontinuation of 3 months of successful treatment with antimuscarinics and the pre-treatment factors that contributed to retreatment. Materials and Methods: Sixty-eight women(mean age 51.4 years) with improvement in the symptoms of OAB after 4 weeks of treatment with propiverine hydrochloride(20mg/day) were prospectively enrolled in a protocol consisting of 8 further weeks of medication and a 4-week period of discontinuation. The frequency-volume charts were assessed before treatment, after the 12 weeks of therapy, and 4 weeks the end of the therapy. Changes in the frequencies, nocturia, urgency scores and urge incontinence at 12 and 16 weeks were evaluated. Results: All of the OAB symptoms 4 weeks after discontinuation of medication remained improved compared to those initially recorded, but then deteriorated during further medication. At the baseline, and 12 and 16 weeks, the mean frequencies, nocturia and urgency scores per day were 11.2, 7.3 and 8.3, 1.6, 0.4 and 0.8, and 1.7, 0.6 and 1.2, respectively. The retreatment rate was 35.3%. Patients in the retreatment group were older (58.8 vs. 47.3 years, p<0.001) and had higher initial urgency scores(1.9 vs. 1.6, p=0.034). In an urodynamic study of 23 patients, those without detrusor overactivity (DO) maintained a significantly improved frequency after cessation of mediation, whereas those with DO(60.9%) did not. The retreatment rate was higher in patients with DO, but the difference was not significant. Conclusions: Three months of antimuscarinic therapy for OAB may not be sufficient. Older patients, or those with severe urgency, may be more likely to return to treatment.

Efficacy of terazosin for overactive bladder symptoms and sexual function in patients withoveractive bladder and symptomatic benign prostatic hyperplasia: a prospectivemulticenter trial

두진경,백재승,주명수,이규성,정문기,박광성,황태곤 대한배뇨장애요실금학회 2008 International Neurourology Journal Vol.12 No.1

Objective: This study is to evaluate the efficacy of terazosin in the treatment of overactive bladder (OAB) symptoms and sexual dysfunction in patients with symptomatic benign prostatic hyperplasia (BPH) and OAB. Methods: Of 200 men aged 50-80 years with symptomatic BPH, an International Prostatic Symptom Score (IPSS) ≥8 accompanied by OAB symptoms, 185 patients completed treatment with terazosin 2-5 mg once daily for 8 weeks. Patients were asked to complete a voiding diary, the International Index of Erectile Function (IIEF) questionnaire, and the IPSS at baseline, 4 and 8 weeks. Results: 8-week terazosin treatment improved OAB symptoms as well as reducing IPSS (19.8 to 12.7) and IIEF (34.4 to 37.4) scores. OAB symptoms improved significantly, irrespective of symptom severity by the IPSS, but the IIEF score only increased in patients with severe symptoms. Conclusions: Additional studies are needed to further evaluate the placebo effect. However, terazosin monotherapy is effective in patients with symptomatic BPH and OAB, and may increase sexual function in patients with severely symptomatic BPH.

신우요관이행부폐색에서 내신우절개술의 장기 치료효과

Purpose: The treatment outcome of endopyelotomy is now being re-evaluated in the era of laparoscopic pyeloplasty. This study was performed to evaluate the long-term success rate of an endopyelotomy for the treatment of an ureteropelvic junction obstruction(UPJO). Materials and Methods: Between January 1995 and December 2003, 77 patients with an UPJO(mean age 35.2±13.89) underwent 85 endopyelotomies, with a percutaneous approach in 10 and a retrograde approach in the other 75 cases. The mean number of the procedure was 1.14, with 69 patients undergoing a single procedure. Endopyelotomies were performed using either a cold knife(n=26), Ho:YAG laser(n=47) or a hook electrode(n=12). Treatment success was defined as symptomatic relief, with radiographic resolution or stabilization of renal function in the excretory and/or diuretic renograms. A Kaplan-Meier curve of the long-term success was generated, and the preoperative hydronephrosis and renal function correlated with the success rate. Results: With a median follow-up of 37.1 months(3-98), the overall success rate was 67.5%. The median time to failure was 7.7 months(1-50). The Kaplan-Meier estimates of success were 87.8, 76.9, 72.2, 68.7, 64.8 and 61.6% at 1, 12, 18, 24, 36 and 60 months, respectively. The success rate was not significantly affected by the etiology, the approach and the incisional methods. The degree of hydronephrosis and renal function showed no significant correlation with the success rate. Conclusions: The success rates of an endopyelotomy decreased with increasing follow-up period. In our conclusion, a long-term follow-up, at least as long as 36 months, is mandatory in patients having undergone an endopyelotomy for an ureteropelvic junction obstruction, although the majority of failures were found within 1 year.

건강검진에 의해 발견된 비뇨기 종양

Purpose: The efficiency of the initial screening methods for the detection of urologic malignancies was evaluated with regard to each cancer detection rate. Materials and Methods: Of the 117,023 people(Male:Female=1.5:1) who received general health examinations between 2000 and 2003, 4,000(3.42%) were referred to the department of urology. It was recommended that the referred patients receive the following additional tests: intravenous pyelography(IVP) and cystourethroscopy for microscopic hematuria, a prostate biopsy after digital rectal examination to elevate prostate-specific antigen(PSA) above 4ng/ml and dynamic computerized tomography of the kidney for any abnormality on the ultrasonography. Results: A microscopic hematuria was detected in 2,253 people(1.93%), PSA evaluated in 620(0.89%) and an abnormality of the kidney on ultrasonography in 1,127(0.96%). One diagnosis was of a bladder tumor, which turned out to be a pTaG2. Twenty seven were found to have prostate cancer, which was organ confined in 13, locally advanced in 7 and systemically advanced in 3. Four men refused further evaluation or management. A renal cell carcinoma(stages pT1a-bN0M0G1-3) was diagnosed in the 10 people having undergone partial or radical nephrectomies and 2 having undergone a nephroureterectomy were diagnosed with a transitional cell carcinoma(stages pT1 and 3bN0M0G3) of the renal pelvis. Conclusions: In the screening of kidney and bladder cancers, the detection rates and cancer stages attributed to ultrasonography and microscopic hematuria are lower. However, the rates of prostate cancer detected by PSA, and their stage, both seem to be higher. It is our belief that greater information and an earlier PSA test will allow the detection of prostate cancer at a lower stage. (Korean J Urol 2004;45:1089-1094)

BLT 방정식과 수치해석 기법을 이용한 전송 선로의 커플링 효과 분석

두진경(Jin-Kyoung Du),안재운(Jae-Woon Ahn),황선묵(Sun-Mook Hwang),육종관(Jong-Gwan Yook) 대한전기학회 2012 전기학회논문지 Vol.61 No.1

The electromagnetic topology and the BLT equation has been used as useful techniques to analyze coupling effects of huge devices. But in the case of systems including complex parts, applying the BLT equation can be difficult to manifest the complex parts with analytic solutions. To resolve this problem, a numerical method can be used to parts of the whole system in advance. In this paper, a microstrip line filter is analyzed using the BLT equation combined with numerical solutions. Consequently, achieved graphs from the BLT equation show good agreements with graphs obtained using a numerical method only.

인공위성과 지상의 원활한 통신을 위해서는 통신 시스템의 성능 등을 이용해 링크를 분석하여 링크 마진이 3dB 이상이 되도록 설계해야 한다. 또한 궤도 정보 등을 바탕으로 지상국과의 통신이 가능한 시간을 확인하여 위성의 작동 모드를 변경하도록 설계해야 한다. CANYVAL 위성은 3U 의 큐브 위성 두 대를 이용한 편대비행을 수행하여 상대 궤도와 자세를 결정하고 제어하는 임무를 수행하고, 이를 위해 지상국과의 통신 및 위성 간 통신을 수행한다. 본 논문에서는 설계 된 CANYVAL 위성의 통신 시스템과 지상국의 성능을 이용하여 세 가지 종류의 링크를 분석 한 결과 안정적인 통신이 가능함을 확인하였다. 또한 궤도와 통신 시스템의 정보를 이용해 지상국과 통신 가능한 시간을 구하여 미션 기간 동안 17GB 의 데이터 전송이 가능함을 분석하였다. For stable communication between a ground station and a satellite, link margin based on properties of communication system should be designed as larger than 3dB. Also, communication time based on orbit properties should be calculated to manage mission modes. CANYVAL is a formation-flying mission which is composed of two 3U cube-satellites. The two satellites require determination and control of relative orbit and attitude to demonstrate a virtual telescope technology. They communicate with each other by inter-satellite link and with ground station. This paper analyzed link budget and communication strategy for the CANYVAL and designed three communication modes for the mission. Communication times are also calculated under the designed orbit and communication system. During the mission time, CANYVAL can transmit about 36GB to ground station.
