Treatment efficacy and outcomes using a third generation shockwave lithotripter.

摘要: Objectives To evaluate the clinical efficiency of a third generation electromagnetic shock wave lithotripter, Lithoskop® (Siemens, Erlangen, Germany), regarding outcomes, stone disintegration, retreatment and complication rates. To compare results Lithoskop with other currently available systems reference standard HM-3 (Dornier MedTech Europe GmbH, Wessling, Germany). Patients Methods We analysed data from 183 patients, including 13 children, undergoing extracorporeal lithotripsy (ESWL) for renal ureteric calculi collected prospectively populated database. Outcomes were assessed by plain abdominal film kidney, ureter bladder ultrasonography radiopaque computerized tomography radiolucent stones 1 day after treatment 3 months. We size location before treatment, disintegration rate, stone-free residual fragment rates months, along auxiliary procedures complications. Results The mean (range) patient age was 48.6 (1.3–81.4) years, children 8.4 (1.3–16.7) 77% patients male. In all, 46% localized in kidney 54% ureter. Renal upper, middle lower calyx pelvis 9, 29, 30 32% respectively. Ureteric mid- distal 19 52% The median ESWL 10 (4–25) mm 8 (4–28) calculi. The overall rate months 91% (88% 93% calculi); number sessions to achieve these 1.3. Stone-free required determined only size. In 7.1% (n = 13) post-interventional necessary. We observed one perirenal haematoma as major (0.5%), but this did not require any further therapy. Conclusions Clinical are high similar those systems, lithotripter. Retreatment low, supporting use first-line therapy urinary <10 mm, independent location.
