title: The use of the Dornier MPL-9000 lithotripter in the treatment of gallbladder and renal stones. Early experience.
abstract: The experience of two units (Gastroenterology and Urology) of Clínica La Luz, Madrid, in the treatment of gallbladder and renal lithiasis using the Dornier MPL-9000 lithotripter is reported herein. This lithotriptor has been utilized in the treatment of all cases of gallbladder calculi for which it is indicated and renal calculi localized high up (kidney), and in those cases that are difficult to treat with other lithotriptors such as patients with kyphoscoliosis, radiolucent calculi, elderly patients, children, etc.). During the first year the gallstone lithotripsy unit was utilized, 401 patients were referred for treatment. Of these, 180 met the criteria for patient selection. (Over 360 have been treated to date.) Sixty of these 180 patients had a single gallstone of up to 2.5 cm. These 60 patients were selected for the study since they comprised a group where the best results could be expected. The aim of studying this patient group was to evaluate the results achieved by lithotripsy and the short and medium-term outcome in this ideal group of patients. Concerning renal lithiasis, these are the first 100 cases treated with the MPL-9000 (currently over 420 have been treated). Eighty cases had a single calculus (60 caliceal and 20 pyelic), 15 had multiple calculi, and 5 had a staghorn stone. Treatment for gallbladder and renal lithiasis was exclusively by shock waves; i.e., as monotherapy with no other auxiliary procedure. The average number of shock waves used was 2,350 with a mean kV of 18 for gallbladder lithiasis.(ABSTRACT TRUNCATED AT 250 WORDS)
