A novel, dual-probe lithotriptor appears to offer the best features of both pneumatic and ultrasonic devices, and provides a significantly shorter penetration time than a combination pneumatic-ultrasonic device, in vitro research data show. 2005-10-15T04:00:00Z XML http://www.modernmedicine.com/modernmedicine/AUA+2005/Probiotic-treatment-new-lithotriptor-highlight-sto/ArticleStandard/Article/detail/177463?contextCategoryId=9403&ref=25 From surgical techniques to genetic manipulation, researchers continue to find new and novel ways to deal with the age-old problem of stone disease. Urologists are now better equipped to deal with the condition than they have ever been, said Glenn M.
