Treatment of human calculi by extracorporeal shock-wave lithotripsy(ESWL) was introduced for kidney stones in 1980. This technology was then applied to the treatment of bile duct stones and pancreatic stones. Some reports have also shown that disintegration of pancreatic stones by extracorporeal shock-wave lithotripsy is possible with successful subsequent endoscopic extraction of the fragments at home ana abroad. We tried removal of pancreatic calcification stones by endoscopic procedures, but could't be removed because the basket got entagled in the endoscopy. We report one case of this pancreatic calcification stones ; the stones were successfully fragmented and completely removal by extracorporeal shock-wave lithotripsy.

Objectives : The purpose of this study is to report the improvement after the Korean medical treatment about a severe hematuria patient after ureterolith lithotripsy. Methods : This study was carried out on 60 year-old female patient who suffered from severe hematuria. We diagnosed a severe hematuria patient after ureterolith lithotripsy as kidney deficiency and blood deficiency pattern in the symptom-differentiation system of Korean medicine and applied herbal medicine, acupuncture and moxibustion to the patient. Results : After Korean medical treatment, we observed improvement of the symptom process by Numeric Rating Scale (NRS), hematologic findings and urinalysis. Blood count of blood and urine had been in the normal range, and NRS of three symptoms had dropped below 0.5. Conclusions : We concluded that Korean medical treatment was an effective treatment for a hematuria patient after ureterolith lithotripsy.

To determine its usefulness and safety of extracorporeal shock-wave lithotripsy in common bile duct and pancreatic duct stones, we analyzed the results of 13 patients with common bile duct stones and 6 patients with pancreatic duct stones which were removed by endoscopic procedures using the balloon or basket, who was performed the extracorporeal shock-wave lithotripsy using the ultrasonography for stone localization with a spark gap type Lithotriptor(Dernier MPL 9000, Germany). Fragmentation and complete clearance of the common bile duct and pancreatic duct stones were obtained in 19 of 19 patients(100%). Apart from transient attacks of fever in 2 of 13 patients with common bile duct stones(15%) and mild elevation of serum amylase and lipase in 2 of 6 patients with pancreatic duct stones(33%), no other serious side effects were observed. In our experiences, extracorporeal shock-wave lithotripsy is a safe and useful treatment for endoscopically unretrievable common bile duct and pancreatic duct stones.

We studied the sapphire and germanium fibers to determine which optical fiber best transmits Erbium:YAG laser for intracorporeal lithotripsy. Human calculi were ablated with an Erbium:YAG laser in contact mode using two fibers. Optical outputs at the distal end of fibers were measured before and after laser lithotripsy. Upon the irradiation on the calculus with the 50 mJ and 100 mJ pulse energy, the output energy at the distal end of germanium fiber declined to approximately 50% of the input energy. For the sapphire fiber, the output energy at the distal end remained unchanged with 100 mJ input energy; however the output energy had dropped to 50% for 200 mJ input energy. In order to examine how the types of target tissue affect the fiber damage, the sapphire fiber was tested for the irradiation on soft tissue and water as well. No energy decline was observed during soft tissue and water irradiation. We also characterized ablation craters with both optical fibers. Both fibers produced similar craters on calculi in terms of depth and diameter. Sapphire fibers are better suited than germanium fibers for Erbium:YAG lithotripsy in terms of the fiber damage.

1997년 8월부터 2002년 5월까지 서울아산병원에 내원하여 췌관결석 진단을 받은 후, 내시경적 결석제거에 실패하고 ESWL을 시행받은 59명을 대상으로 하였다. 췌관 결석의 방사선학적 특징을 결석 수, 가장 큰 결석의 최대 직경 길이, 결석의 농도, 그리고 생긴 모양으로 분류하였다. 전체대상 59예 중 45예(76.3%)에서 결석의 완전한 제거가 확인되었으며 14예(23.7%)에서는 결석의 완전한 제거에는 실패한 것으로 확인되었다. 1. 단일 결석을 가진 28예 중 21예(75.0%)에서 결석이 완전 제거되었으며, 두 개 이상의 다결석을 가진 31예 중 24예(77.4%)에서 결석이 완전 제거되었다. 2. 결석의 최대 직경이 30m 이하의 경우인 53예 중 41예(77.4%)에서 결석의 완전한 제거가 확인되었으며, 30mm 보다 큰 경우인 6예 중 4예(66.7%)에서 결석의 완전한 제거가 확인되었다. 3. 척추의 체부(body)와 비교한 결석의 농도측면에서, 척추의 체부 보다 농도가 낮은 경우, 즉 비석회화 결석 8예 중 8예(100%) 모두에서 결석이 완전 제거되었으며, 농도가 같은 경우인 43예에서는 37예(86.0%)가 결석의 완전한 제거를 보였으나, 농도가 척추 체부 보다 높은 3예 중 3예(100%) 모두에서 결석의 완전한 제거에 실패하였으며, rim calcified stone 5예 중 5예(100%) 모두에서 또한 결석의 완전한 제거에 실패하였다. 4. 각이진 모양의 결석 9예 중 2예(22.2%)에서 결석이 완전 제거되었으며, 그렇지 않은 원형이나 타원형 모양의 경우인 50예 중 43예(86.0%)에서 결석의 완전한 제거를 확인하였다.

The aim of this study was to determine whether Hounsfield units (HUs), volume, and various void parameters can predict stone fragility in extracorporeal shock wave lithotripsy (ESWL). HU, volume, porosity, number of voids/stone volume, and void distribution of 30 struvite stones were estimated using helical computed tomography (CT) and micro-CT. The number of shock waves necessary for full fragmentation was accepted as a measure of the stone fragility in ESWL. The correlations between the number of shock waves and the HU, volume, porosity, and number of voids/stone volume were examined. The number of shock waves of the two groups according to the void distribution was also compared. Stone volume correlated with the number of shock waves. Shell-patterned struvite stones were significantly less susceptible to fragmentation in ESWL than non-shell-patterned struvite stones. Stone volume and void distribution may be predictors of the outcome of ESWL treatment.

Lesch-Nyhan syndrome is an inborn error of purine metabolism resulting from hypoxanthine-guanine-phosphoribosyltransferase (HGPRT) deficiency and leading to excess purine production and uric acid over-production. It is a very rare X-linked recessive disorder, characterized by movement disorder, cognitive deficits, and self-injurious behavior. However, because of the high incidence of calculi, patients may present for surgery of urinary tract, and have increased risk of difficult intubation, aspiration pneumonia, renal insufficiency or sudden death. We report the case of a 5-year-old boy with Lesch-Nyhan syndrome who underwent successive extracorporeal shockwave lithotripsy under general anesthesia.

Objectives This report aimed to review literatures using extracorporeal shock wave with syndrome differentiation theory. Methods By March 3, 2020, five foreign electronic databases (PubMed, Web of Science, Cochrane Library, EMBASE, CAJ) and six Korean medical electronic databases (KMBASE, KISTI, KISS, NDSL, DBpia, RISS) were reviewed with the key word 'extracorporeal shock wave' and 'syndrome differentiation'. We did not impose restrictions on age, gender, treatment methods, duration, results and the design of the paper. Results Twelve papers met the inclusion criteria. Seven papers used extracorporeal shock wave lithotripsy with syndrome differentiation theory and six out of seven papers treated urologic stones using extracorporeal shock wave lithotripsy. The other five papers used extracorporeal shock wave therapy with syndrome differentiation theory and four of them treated musculoskeletal disorders. However, the data of the characteristics of extracorporeal shock wave was insufficient. Conclusions After thorough review, it is considered to be meaningful to treat urologic stones and musculoskeletal disorders using extercorporeal shock wave with syndrome differentiation theory. However, some of the literatures were limited in their feasibility and reliability in terms of research design. In addition, the data regarding the strength of the extracorporeal shock wave applied on each acupoints was insufficient. Therefore, further study on the use of extracorporeal shock wave on acupoints should be conducted.
