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.

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.

Background: Extracorporeal shock wave therapy (ESWT) is one of the treatment options used for patients with myofascial pain syndrome (MPS), although its effectiveness is controversial. The purpose of this study was to evaluate the effectiveness of ESWT in the treatment of MPS in terms of pain relief and functional improvements. Methods: We assessed 93 patients with MPS who underwent ESWT from March 2009 to July 2014. After exclusion of 25 patients with shoulder diseases, 68 patients were enrolled in the study. The mean follow-up period was 7.5 months (${\pm}4.2weeks$), and the average duration of symptoms was 5 months (range, 2-16 months). ESWT was applied to intramuscular taut bands and referred pain areas once a week for 3 weeks. Visual analog scale (VAS) pain scores and American Shoulder and Elbow Surgeons (ASES) scores were obtained at an initial assessment and at the 6-week, 3-month, and 6-month follow-up assessments. Results: VAS pain scores and ASES scores improved significantly after 3 sessions of ESWT (p<0.05). Both scores were improved, although not significantly, after 6 weeks (p>0.05). Conclusions: ESWT is an effective treatment option for patients with MPS.

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.

체외 충격파 쇄석술시 쇄석기종에 따라 각각 장단점이 있으며, 전 처치로 인한 여러 가지 부작용이 보고되고 있다. 이에 전자기식 ESWL시 하부결석환자에서 적합한 충격파의 강도를 찾아보고, C-arm의 총 가동시간을 측정해 보았다. 본 연구는 2014년 1월부터 6월까지 경북지역 일개시의 C대학병원에서 전 처치를 시행하지 않고 ESWL을 받은 65명의 환자를 대상으로 하였다. 성비는 남자가 48명, 여자가 17명으로 남자가 더 많았으며, 연령은 50대가 가장 많았다. 하부요로결석의 발생은 왼쪽이 더 많았으며, 결석의 크기는 5mm 이하가 39명으로 가장 많았다. 적합한 충격강도는 1의 강도이며 통증을 호소하는 경우 C의 강도로 전환하여 충격을 가할 수 있다. 또한 C-arm의 총 가동시간은 $241.73{\pm}30.37$초로 나타났으며, 이것은 하부요로결석의 크기와 유의한 차이를 보였다(p<0.05). 따라서, ESWL시 전처치를 시행하지 않고 시술을 할 경우 요관 결석의 부위에 따라 적합한 충격강도와 충격빈도의 기준이 필요로 하며, C-arm 총 가동시간도 요관 결석의 발생부위에 따라 방사선으로 인한 피폭을 최소화하기 위한 총 가동시간에 대한 기준이 필요할 것으로 사료된다.
