Objective: To improve the symptoms of patients with urolithiasis and chronic dyspepsia using OCNT. Methods: A 60-year-old Korean male who had undergone extracorporeal shock wave lithotripsy six times without natural stone removal was treated with OCNT for two weeks. Results: The stones were removed through adequate hydration and light exercise while undergoing OCNT. Conclusion: The application of OCNT in patients with urolithiasis can be beneficial in alleviating symptoms.

본 연구는 회전근개건염 환자에게 체외충격파 치료를 실시하여 통증과 기능에 어떠한 영향을 미치는지 알아보고자 하였다. 2011년 9월부터 2012년 2월까지 초음파를 통해 회전근개건염 진단을 받은 환자 32명(치료군 16명, 대조군 16명)을 대상으로 치료군에게 4주 동안 체외충격파 치료를 실시하였다. 통증은 visual analog scale(VAS)와 pressure pain threshold(PPT)를 사용하여 평가하였고 기능평가는 위해 Constant and Murley Scale(CMS)와 Simple Shoulder Test(SST)를 통해 평가 하였다. 연구 결과 체외충격파 중재 후 치료군에서는 대조군에 비해 통증과 관절가동 범위, 근력, 기능 등 모든 부분에서 유의한 변화를 보였다. 이 결과는 회전근개건염 환자에게 체외충격파 치료가 어깨의 통증과 기능에 영향을 미칠 수 있는 가능성을 시사하고 효과적인 치료방법이라 할 수 있다.

Symptoms of caliceal diverticular stones are commonly associated with pain, recurrent urinary tract infection and hematuria. The aim of this study is to select the proper patient for the application of more successful extracorporeal shock wave lithotripsy(ESWL) as a treatment of caliceal diverticular stone. 16 patients with caliceal diverticular stones were treated with ESWL, and all patients had single caliceal diverticulum. The diagnosis of caliceal diverticulum with stones was made by intraveneous pyelography to all patients. On these intravenous pyelogram, we also classified diverticular type, whether the diverticular neck is connected with urinary tract patently, diverticular site and stone number and size. All patients were followed after ESWL by plain film of the kidneys, ureters and bladder and interviewed. Of all patients 44% was shown stone-free completely, also 83% was rendered symptom-free. All patients whose diverticular neck connected with urinary tract patently on the intraveneous pyelogram became stone- free. Of solitary stone 60% and multiple stones(more than 2) 17% became stone free. All patients rendered stone-free became symptom-free, and of patients with residual stones 44% became symptom-free. The patients with infection before ESWL 75% had residual stones, of these patients 33% had slightly flank pain, and 25% of patients with stones recurred become stone-free. We propose that more successful ESWL for patients with caliceal diverticular stones select satisfactory patients including that the diverticular neck is connected with urinary tract patently, solitary stone and no infection simultaneously.

Extracorporeal shock wave lithotripsy (ESWL) with adjunctive oral litholytic therapy has proven to be a useful treatment in selected patients with gallbladder stones. To study the effect of ESWL on gallbladder dynamics, $^{99m}Tc-DISIDA$ hepatobiliary scintigraphy was done for 25 patients with symptomatic gallstones and 10 normal controls. Of these 25 patients, 15 were treated with ESWL and adjunctive oral litholytic agents (ESWL group) and 10 were treated only with oral litholytic agents (UDCA group). After overnight fast and gallbladder visualization on a routine hepatobiliary scintigraphy with 7mCi of $^{99m}Tc-DISIDA$, subjects were given fatty meal and imaged with a gamma camera interfaced to a computer (1 frame/minute for 70 minutes). A gallbladder time-activity curve was generated and latent period (LP), ejection period (EP), ejection fraction (EF) and ejection rate (ER) were calculated. ESWL group were studied before, 1day after and 2weeks after ESWL, and WDCA group were studied before and 2weeks after starting oral medication. Mean basal EF was significantly reduced in patients but other parameters were not reduced. In ESWL group, mean EF and mean ER at lday after ESWL were reduced. In 3 of them, gallbladder was not visualized at all. Two weeks after ESWL, however, all parameters were recoverd to basal level. In UDCA group, all parameters were not changed significantly during medication. We can conclude that ESWL has such immediate adverse effect on gallbladder dynamics as reducing contractility and nonvisualization of gallbladder but it has no long-term effect.

체외 충격파 쇄석술 (ESWL)은 인체 외부에서 발생된 충격파를 인체 내부의 결석 부위에 집속하여 결석을 분쇄하고 치료 효과를 얻는 혁신적 치료술이다. 충격파의 압력 및 파형은 결석의 분쇄 효과 즉 치료 효과를 좌우한다. 체외에서 충격파의 압력은 고감도 하이드로폰을 이용하여 측정할 수 있지만, 인체 체내에서, 특히, 비침습적으로 충격파를 측정하기는 매우 어렵다. 본 논문에서는 ESWL 충격파에 의해 활성화된 체내의 기포군으로부터 방출된 음향 신호 (CIAE)를 측정하여 비침습적으로 충격파의 압력을 추정하는 방법을 실험하였다. 충격파 압력의 추정은 측정된 CIAE 신호에서 1차 기포군 파열음과 2차 파열음 간의 시간 지연은 충격파의 압력과 선형적인 관련성 가진다는 실험 결과 (Coleman et al 1996)에 근거하고 있다. 본 논문에서는 충격파 압력 측정 시스템을 구성하여 생체 외 실험을 수행하였고, 개발된 시스템의 임상적인 활용 가능성을 확인하였다.

Purpose : The purpose of this study was to assess the effectiveness of Extracorporea Shock-wave therapy(ESWT) on the pain and improvement of wrist extensor strength which is one of the available medical treatment in patients with lateral epicondylitis. Object and Methods : The subjects of this study were consisted of 15 patients with lateral epicondylitis, These medical treatments was conducted total 6 time for 3 weeks. In the ESWT application group. To investigate the effectiveness of the treatment after ESWT treatment, Pain was measured by visual analogue scale(VAS) which is divided into 10 ranks and wrist extensor strength was measured by Aneroid phygmomanometer Results : 1. It was showed that VAS and wrist extensor strength before treatment and after two treatment(1 week) were no significant differences(p<0.05). 2. It was showed that VAS and wrist extensor strength before treatment and after four treatment(2 week) were significant differences(p<0.05). 3. It was showed that VAS and wrist extensor strength before treatment and after six treatment(3 week) were significant differences(p<0.05). Conclusion : We think that ESWT for the patients with lateral epicondylitis. is effective to wrist extensor strength and decrease of pain.

본 논문은 체외 충격파 파쇄 장치를 사용하여 결석을 파쇄할 때 방사되는 소리에 관계된 정보를 분석한 것이다. 먼저, 방사음으로부터 대상물의 진동을 관찰하고, 대상물의 진동과 방사음 간의 관계를 통하여 피크주파수의 변화에 관한 정보를 추출하였다. 다음에는, 초점의 위치에 따른 피크주파수의 변화를 관찰하여 초점의 바로 위나 아래 부분보다 정확한 초점에서 대상물을 진동시키기가 더욱 어렵다는 사실을 입증하였다. 마지막으로, 캐비테이션과 방사음과의 관계를 분석하여 대상물의 파쇄에 더 유리한 위치를 조사하였다.
