Abstract
From July 1988 to August 1991, 174 stone treatments were attempted on 112 stones in 86 patients using a Therasonics dagger lithotriptor. Mea n stone diameter was 13 mm. (range 4 to 60). The success rate (defined as no debris or fragments less than 4 mm. in an asymptomatic patient) was 49% and the retreatment rate was 63%. Subjects reported moderate to severe pain during 70 treatment sessions (42%) despite sedation wit h parenteral narcotics (50 to 100 mg. meperidine and 50 mg. hydroxyzin e intramuscularly). One patient had perirenal bleeding requiring a 7-u nit blood transfusion. Of the treatments 24 (13%) were aborted, 10 due to pain and 13 because of inability of the operator to position the p atient or localize the stone. These results appear to be inferior to t hose reported with alternative lithotriptors. Modifications that have been made in the Therasonics system may improve stone localization and treatment results.
