Objectives: The purpose of this study was to evaluate the association between body mass index (BMI) and severe lower urinary tract symptoms (LUTS) in Korean males. Methods: This study was conducted on males aged ${\geq}50years$ who participated in the 2011 Korean Community Health Survey. LUTS severity was assessed using the Korean version of the International Prostate Symptom Score (IPSS) questionnaire, and was dichotomized as severe (IPSS >19) and non-severe ($IPSS{\leq}19$). BMI was divided into 6 categories: <18.5, 18.5-22.9, 23.0-24.9, 25.0-27.4, 27.5-29.9, and ${\geq}30.0kg/m^2$. To evaluate the relationship between BMI and LUTS, a survey-weighted multivariate Poisson regression analysis was performed to estimate prevalence rate ratios (PRRs). Age, smoking status, alcohol intake, physical activity, educational level, household income, and comorbidities were adjusted for in the multivariate model. Results: A U-shaped relationship was detected between BMI and severe LUTS. Compared with a BMI of $23.0-24.9kg/m^2$, the PRR for a BMI < $18.5kg/m^2$ was 1.65 (95% confidence interval [CI], 1.35 to 2.02), that for a BMI of $18.5-22.9kg/m^2$ was 1.25 (95% CI, 1.09 to 1.44), that for a BMI of $25.0-27.4kg/m^2$ was 1.20 (95% CI, 1.00 to 1.45), that for a BMI of $27.5-29.9kg/m^2$ was 1.11 (95% CI, 0.83 to 1.47), and that for a BMI ${\geq}30.0kg/m^2$ was 1.85 (95% CI, 1.18 to 2.88). Conclusions: This study showed that both high and low BMI were associated with severe LUTS.

The aim of this study is to acquire useful information of lower urinary tract symptom(LUTS) diagnosis through urophonogaphy signal as noninvasive method. The system was implemented to measure urophonography signal, urinary volume and uroflow. The slope of the log-log plot of power spectrum density changed rapidly from $2.01{\sim}2.07$ to over 3.32 when the occlusion rate was 2 mm to 3.8 mm. This information combined with the uroflow parameters could give a useful prediction of lower urinary tract symptoms.

Purpose: The study was done to identify lower urinary tract symptoms (LUTS) and to evaluate the factors affecting LUTS for the people with Parkinson's disease. Methods: The research design was a cross-sectional study with interviews using a structured questionnaire. The participants were 72 patients with Parkinson's disease who were seen in the Neurology clinic of a university hospital from September to November 2005. Results: Mean score of LUTS for the participants was 10.11. In each symptom score of LUTS (range 0-5), weak stream was the highest 2.06, followed by nocturia 1.71, and urgency 1.61. The severity of LUTS was moderate to severe group for 51%. LUTS were significantly different by regular exercise. Positive correlations were observed between Hoehn and Yahr stage (stage of disease severity) and frequencyand between Hoehn and Yahr stage and urgency (r=.280, p=.018; r=.328, p=.005). LUTS were significantly predicted by regular exercise (p=.001) which explained 15.0% of the variance in LUTS. Conclusion: Regular exercise was found to be a very important factor associated with LUTS for patients with Parkinson's disease.

요역동학검사는 하부요로계의 이상증상을 진단하기위하여 수행된다. 일반적으로 임상에서 행해지는 요역동학검사에서는 침습적인 방법으로 방광을 채운 후 배뇨하는 절차를 거친다. 하지만 이러한 방법은 카테터를 삽입해야하므로 환자에게 고통을 수반하게 한다. 본 연구에서는 비침습적이고 보다 편리한 방법으로 하부요로계의 기능을 평가할 수 있는 시스템을 구현하고자 하였다. 비침습적인 방법으로 하부요로증상(lower urinary tract symptoms, LUTS)의 진단을 위하여 배뇨시 요속, 요류음, 비침습적 방광내압을 측정할 수 있는 시스템을 구현하였다. 구현된 시스템은 센서부, 신호처리부, FPGA를 이용한 시스템 제어부 그리고 PC모니터링 프로그램으로 구성하였다. 그리고 구현된 계측시스템의 평가를 위하여 FPGA 시스템 제이부의 시뮬레이션을 수행하였고 인체의 하부요로계를 모식화한 실험장치를 구현하였다. 실험장치를 이용한 측정부의 평가결과 요속측정부의 평균에러율이 1.08%, 계수변화율이 1.48로 평가되었다. 그리고 비침습적 방광내압부는 평균에러율이 2.41%, 계수변화율이 2.81로 나타났다. 요류음신호의 시간영역과 주파수영역에서의 분석위해 평균실효치전력(average RMS power)과 주파수영역에서의 중심주파수(median frequency, MF)를 분석하였으며, 그 결과 $60{\sim}160Hz$의 중심주파수대에서 폐색을 가장 잘 반영하였다.

Objective: To evaluate the safety and feasibility of prostatic artery embolization (PAE) via transradial access (TRA) compared with transfemoral access (TFA). Materials and Methods: This retrospective study included 53 consecutive men with lower urinary tract symptoms (LUTS) who underwent PAE between September 2018 and September 2021. Thirty-one patients (mean age ± standard deviation: 70.6 ± 8.4 years) were treated with TFA, including 14 patients treated before adopting TRA. Since December 2019, TRA has also been attempted with the procedure's selection criteria of patent carpal circulation and a height ≤ 172 cm, with 22 patients treated via TRA (69.1 ± 9.6 years). Parameters of technical success (defined as successful bilateral embolization), clinical success (defined as LUTS improvement), procedural time, radiation dose, and adverse events were compared between the two groups using the Fisher's exact test, independent sample t test, Wilcoxon signed-rank test, or Mann-Whitney test. Results: All patients received at least one-side PAE. Technical success of PAE was achieved in most patients (TRA, 21/22; TFA, 30/31; p > 0.999). No technical problem-related conversion from TRA to TFA occurred. The clinical success rate was 85% (11/13) in patients with TRA, and 89% (16/18) in patients with TFA for follow-up > 2 weeks post-PAE (median, 3 months) (p > 0.999). The median procedure time was similar in both groups (TRA, 81 minutes vs. TFA, 94 minutes; p = 0.570). No significant dose differences were found between the TRA and TFA groups in the dose-area product (median Gycm², 95 [range, 44-255] for TRA and 84 [34-255] for TFA; p = 0.678) or cumulative air kerma (median mGy, 609 [236-1584] for TRA and 634 [217-1594] for TFA; p = 0.551). No major adverse events occurred in either of the groups. Conclusion: PAE via TRA is a safe and feasible method comparable to conventional TFA. It can be safely implemented by selecting patients with patent carpal circulation and adequate height.

국내외 학술지중 배뇨장애에 대한 침치료의 연구 동향을 문헌고찰 연구, 생리적 기전 연구, 임상효과 연구로 나누어 분석한 결과 다음과 같은 결과를 얻었다. 1. 23 편의 논문 중 review study가 3편, experimental study 6편, clinical study가 14 편이었다. 다양한 Journal에 발표되고 있었는데, review study는 모두 국내 학술지에 게재 된 논문이었고, 2000년 이후로 점차 연구의 양과 관심이 증대되고 있는 추세였다. 2. 배뇨장애는 하부요로증상의 다양한 증상을 포괄하는 것으로 한의학적인 측면에서는 융폐, 소편부금(小便不禁), 빈요(頻尿), 급박요(急迫尿), 요실금(尿失禁), 림증(淋證), 야뇨(夜尿), 난요(難尿), 점적요(點滴尿), 지연요(遲延尿)등에 해당하는데, 그 대부분의 유발 원인은 신기부족(腎氣不足)등의 하초허한(下焦虛寒)에 기인하는 것으로 판단되며, 간기울결(肝氣鬱結)등의 정서적 자극과 습열(濕熱) 및 어혈(瘀血)등의 원인에 의해서도 발생할 수 있다. 3. 배뇨장애에 대한 침구치료의 생리적 기전을 대략적으로 요약한다면 침자극에 의해 부교감 신경, 대뇌의 수면-각성 체계, 뇌교 및 척추 배뇨 센타, 음부신경/골반신경을 통해 방광에 영향을 주어 방광용량의 확장 또는 배뇨 수축의 억제작용을 하는 한편, 척추 환상 회로 나 신경연접부의 지속성 흥분을 통하여 요도주의 근육에 영향을 주는 것으로 생각되어 진다. 4. 배뇨장애에 대한 침구치료의 임상효과를 요약 한다면, 융폐, 소편부통(小便不通)에 속하는 신경인성 방광(Neurogenic Bladder), 소편부금(小便不禁), 빈요(頻尿), 급박뇨(急迫尿)에 해당하는 요실금(尿失禁)(Incontinence), 림증(淋證)에 해당하는 방광염(Cycitis), 액요(液尿) (Nocturnal Enuresis), 잡요(雜尿), 점적요(點滴尿), 지연요(遲延尿)에 해당하는 전립선염/골반통 증후군 (Prostatitis/Pelvic Pain Syndrom)등의 하부 요로증상에 침구치료는 유의미한 효과가 있다. 이상으로 국내 및 해외 연구는 최근들어 더욱 활발히 연구되고 있는데, 특히 해외연구는 배뇨 장애의 침구치료의 생리적 기전 분야에서 다양 하게 시도되고 있었다. 향후 고령화 사회로 진입 하는등 사회여건상 이와같은 다양한 배뇨장애 환자의 증가는 물론 치료욕구의 증대가 예상되는 바 이러한 생리적 치료기전의 연구 및 다양한 질환에 대한 임상연구를 시도함으로써 표준적인 치료기술의 개발이 필요할 것으로 사료된다.
