Twenty-four rats were divided into four equal groups. All rats in one group were matched with the corresponding rats in the other three groups according to tumor size. Hyperthermia was created by the resistive heating of a 22-gauge 1.5-cm needle; HESW were generated by the Dornier XL-1 experimental lithotripter. In two hyperthermia treatments administered 48 hours apart, the tumor was heated to 46.5 degrees C for 2 hours; HESW treatment involved 1,600 shocks at 18 kV. Twenty-nine days after initiation of this study, animals were sacrificed and tumor growth calculated. Tumor growth in group 1 (combined hyperthermia and HESW) was significantly delayed between the 7th and 29th day (p = 0.05). In group 2 (HESW alone), tumor growth was significantly delayed between the 7th and 22nd day (p = 0.01), while tumor growth in group 3 (hyperthermia alone) was delayed between the 3rd and 22nd day (p = 0.02). On day 22, mean percent change in tumor growth in the control group exceeded that of group 1 by 449% (p = 0.015) as well as that of groups 2 and 3, by 350% (p = 0.034) and by 268% (p = 0.049), respectively. As previous reports demonstrate the efficacy of hyperthermia in combination with irradiation or chemotherapy for the treatment of prostate carcinoma, our results indicate hyperthermia in combination with HESW may also be a useful treatment modality.</p>","PeriodicalId":80212,"journal":{"name":"The Journal of lithotripsy & stone disease","volume":"2 3","pages":"211-9"},"PeriodicalIF":0.0,"publicationDate":"1990-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21021092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the 6-month gallbladder clearance results appear to be remarkably similar (36%-43% in less than 20-mm solitary stones), they do not appear to match the results obtained by the Munich group in their first 175 patients (63% clearance at 4-8 months). We review the currently available American data and describe our on-going national clinical trial with the Technomed Sonolith 3000 investigation. In this trial, patients are randomized to lithotripsy plus ursodiol (Actigall,¿ Ciba Geigy), or lithotripsy alone to determine the effect of oral bile salts on the gallbladder fragment clearance rate. To date, the early success rate is clearly better in the GSL plus ursodiol arm. Following one or two lithotripsy sessions, 62.1% of patients with solitary stones, 5-20 mm in size, have had fragmentation to 7 mm or less. In the same group, 39.1% of gallbladders are clear at 6 months. While the 6-month gallbladder clearance rate appears to be a reliable indicator of eventual gallbladder status it should not be regarded as the end point of therapy and it clearly does not represent the final efficacy rate for gallstone lithotripsy. A review of the results obtained from on-going American IDE trials is compared with the published German results using GSL and combination oral dissolution therapy.</p>","PeriodicalId":80212,"journal":{"name":"The Journal of lithotripsy & stone disease","volume":"2 3","pages":"199-204"},"PeriodicalIF":0.0,"publicationDate":"1990-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21021089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
