Piezoelectric lithotripsy was undertaken on 50 patients with gallbladder stones, none of them requiring anaesthesia, analgetics or sedatives. Stone fragmentation was achieved in all patients during the first treatment. In 44 patients the maximum fragment size was less than 50% of the initial stone diameter. The mean maximum fragment size after the first treatment was 4.3 mm (+/- 3.3 mm). After a follow-up of 0-2 months in 14 of the 50 patients and of 2-4 months in 6 of 13 patients, no more stones could be seen by ultrasonography. After an average period of 8 weeks, 17 of 50 patients were free of stones. Piezoelectric lithotripsy did not have any severe side effects besides a mild pancreatitis in one patient.
对50例胆囊结石患者进行了压电碎石术，无一例需要麻醉、镇痛药或镇静剂。所有患者在首次治疗期间均实现了结石破碎。44例患者的最大碎片尺寸小于初始结石直径的50%。首次治疗后的平均最大碎片尺寸为4.3毫米（±3.3毫米）。50例患者中的14例经过0 - 2个月的随访，13例患者中的6例经过2 - 4个月的随访，超声检查未见更多结石。平均8周后，50例患者中有17例结石消失。除1例患者出现轻度胰腺炎外，压电碎石术没有任何严重副作用。
