The ureteroscope has an 8.3F outer diameter with a fiber optic core that allows some flexibility of the shaft. It has a 4.0F working channel that allows simultaneous use of 3F instruments and irrigation. Twenty-three patients had upper ureteral calculi and 48 patients had lower ureteral calculi. Thirty-six patients did not require ureteral dilation and the remainder had minimal dilation to 10-12F. Fifty-one patients underwent laser lithotripsy, 14 patients underwent basket extraction, and six patients had both. Five patients required use of a second flexible ureteroscope. Seventy-seven percent of the patients went home the day of the procedure, 16% stayed one night in the hospital, and the remaining 7% had longer hospital stays. No major complications or infections were noted. Only 11% of the patients required IV or IM narcotics for pain management post-operatively. The stone-free results at 1 month were 96% for lower ureteral calculi and 91% for upper ureteral calculi. We have found this ureteroscope to be similar to other rigid mini-ureteroscopes with some additional advantages. A larger working channel, increased flexibility/steerability, and improved optics make it useful for treating ureteral calculi in the lower ureter in men and the entire ureter in women.","PeriodicalId":80218,"journal":{"name":"The Journal of stone disease","volume":"5 4","pages":"213-6"},"PeriodicalIF":0.0,"publicationDate":"1993-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21018745","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}

{"title":"Extracorporeal shock wave lithotripsy treatment of lower caliceal stones: an update on the use of a cobra catheter for direct irrigation.","authors":"E R Nicely, M I Maggio, C E Brown","doi":"","DOIUrl":"","url":null,"abstract":"As the general experience with extracorporeal shock wave lithotripsy (ESWL) for renal calculi broadens, it is increasingly evident that the clearance of stone fragments in lower pole calices needs to be improved. The stone-free rate posttreatment for lower caliceal stones is consistently less than that for other upper tract locations. Utilization of a cystoscopically placed cobra catheter for directed irrigation during ESWL with a Dornier HM4 lithotripter resulted in an increase of our lower caliceal stone-free rate to 64% (29/45) at 1 month follow-up and 73% (33/45) at 3 months follow-up compared to 36% (15/42) of randomly selected controls at 1 month (p less than 0.007) and 54% (23/42) at 3 months (p < 0.070). Patients were included in the study if they had a solitary calculus, less than 2 cm in size, located in a normal lower pole calix and had no indwelling stent placed by the referring physician. The cobra catheter was positioned in the appropriate calix with fluoroscopic guidance under intravenous sedation. Statistical analysis was performed using Pearson's Chi-square test. We conclude that the pre-ESWL treatment placement of a cobra catheter into the lower pole calix and intermittent irrigation during the procedure is a useful adjunct in the successful treatment of lower caliceal calculi.","PeriodicalId":80218,"journal":{"name":"The Journal of stone disease","volume":"5 3","pages":"155-8"},"PeriodicalIF":0.0,"publicationDate":"1993-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21017583","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}

Prior studies have not reported injury to the gallbladder or adjacent liver following ESWL. Our study evaluated 29 patients that were treated with high kV ESWL. Magnetic resonance imaging (MRI) was used to study the gallbladder and adjacent liver for possible injury resulting from the high-energy treatment. The patients, selected using the Dornier MPL-9000 United States protocol, underwent ESWL using 18-24 kV (average 21 kV). MRI was done both pre and post-ESWL in all 29 patients. Ten patients had a second treatment to reduce fragment size and, subsequently, had an additional MRI examination. Spin echo MRI images were obtained at the level of the gallbladder fossa using a 0.5-Tesla ESATOM RM 5000 (ESAOTE Biomedica, Genva, Italy.) superconductive unit. Both T1- and T2-weighted images were obtained. In 26 patients the hepatic parenchyma was normal post-ESWL. Two patients had a hyperintense region on T1-weighted images post-ESWL that was felt to be related to pericholecystic fat. A third patient had an abnormality detected on T2-weighted images that was thought to be due to hepatic edema or microhemorrhage. No significant changes were shown by laboratory or concurrent ultrasound examinations. Repeat MRI examinations in these three patients were normal. High-energy ESWL appears as safe as low-energy ESWL in the treatment of patients with symptomatic gallstones.","PeriodicalId":80218,"journal":{"name":"The Journal of stone disease","volume":"5 3","pages":"159-64"},"PeriodicalIF":0.0,"publicationDate":"1993-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21017584","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 perfusion flow rate was kept constant, the arterial perfusion pressure was recorded to assess changes in vascular resistance. Immediately after shock wave application, perfusion pressure decreased by 20%-30%, followed by a short, relative pressure rise that did not reach pretreatment values. Fifteen-twenty minutes later, arterial perfusion pressure reattained pretreatment values. Subsequent to treatment, urine flow decreased by greater than 50%. The observed pressure rise was also induced in nontreated kidneys by perfusion with the effluent of treated kidneys indicating that this is based on a humoral mechanism. On the other hand, shock wave application to formalin fixed kidneys only caused a marked decrease in arterial perfusion pressure, suggesting that this effect is due to a pure mechanical interaction of the shock wave also found with denaturated kidneys. The observed decrease of urine flow is probably caused by a decreased filtration rate. Since this was not the case in nontreated kidneys being perfused with the effluent of treated kidneys, the reduction of urine flow after extracorporeal shock wave lithotripsy does not appear to be mediated by a humoral factor, but is more likely a result of the mechanically-induced vasodilation with consecutive decline of the glomerular filtration rate.","PeriodicalId":80218,"journal":{"name":"The Journal of stone disease","volume":"5 3","pages":"172-8"},"PeriodicalIF":0.0,"publicationDate":"1993-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21017585","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}
