The Piezolith 2200 as an extracorporeal shock wave lithotripter uses piezoelectrically generated, high-energy sonic impulses for treatment of urinary calculi; the shock wave generator is self-focussing. Localization of concrements is performed by means of ultrasound imaging. Treatment with the Piezolith 2200 is painless for the patient and thus possible without anesthesia and analgesia. We report on 806 cases of treatment involving a total of 572 kidneys in 567 patients (561 adults, 6 children) suffering from calculi of various sizes in the renal pelvis (n = 126), calculi in the calyces (n = 384), partial (n = 24) or full (n = 19) staghorn calculi, as well as calculi in the upper part of the ureter (n = 19). In 88% of these cases the concrements could be removed completely. Since cardiac activity is not influenced by piezoelectrically generated high-energy impulses, this procedure is particularly suited to the treatment of patients with heart problems.
Piezolith 2200体外冲击波碎石机利用压电产生的高能声波脉冲治疗尿路结石；冲击波发生器为自聚焦式。结石定位通过超声成像进行。使用Piezolith 2200治疗对患者无痛，因此无需麻醉和镇痛即可进行。我们报告了806例治疗病例，共涉及567例患者的572个肾脏（561例成人，6例儿童），这些患者患有肾盂内各种大小的结石（n = 126）、肾盏结石（n = 384）、部分（n = 24）或完全（n = 19）鹿角形结石，以及输尿管上段结石（n = 19）。在这些病例中，88%的结石能够被完全清除。由于心脏活动不受压电产生的高能脉冲影响，该方法特别适合治疗有心脏问题的患者。
