To report our preliminary series with the Doli S EMSE 220F-XXP, the upgraded version of the previous Dornier Lithotripter S EMSE 220, for treatment of ureteral stones.
Since July 2006, a total of 200 patients with ureteral stones were submitted to shock wave lithotripsy (SWL) with Doli S EMSE 220F-XXP. Mean stone size was 9.3 mm (range 6-18 mm). Ureteral stone location was proximal in 75, middle in 34, and distal in 91. Follow-up was carried out at 6 weeks after the treatment, by means of kidney-ureter-bladder (KUB) film and ultrasound, or helical computed tomography (CT).
The overall stone-free rate was 89.5%, and the effectiveness quotient was 80. Stratifying by stone site, the stone-free rate was 93.3, 67.6, and 94.5% for proximal, middle, and distal location, respectively. Mean number of sessions per patient was 1.14. Analgesia with intravenous ketorolac or tramadol was required in 42.5% of cases. No significant side-effects were recorded.
The new Doli S EMSE 220F-XXP provides similar characteristics to the Doli S EMSE 220 in terms of safety and lack of major complications, when dealing with ureteral stones; the improvement in stone disintegration is particularly evident for distal location, for which the number of pulses and the intensity of treatment can be greatly increased and the upgraded power of the device can be widely applied.
报告我们使用 Doli S EMSE 220F-XXP（前 Dornier Lithotripter S EMSE 220 的升级版）治疗输尿管结石的初步系列结果。
自 2006 年 7 月以来，共有 200 例输尿管结石患者接受了 Doli S EMSE 220F-XXP 的冲击波碎石治疗。平均结石大小为 9.3mm（范围 6-18mm）。输尿管结石位置为近端 75 例，中段 34 例，远端 91 例。治疗后 6 周通过 KUB 片和超声或螺旋 CT 进行随访。
总的结石清除率为 89.5%，有效率为 80%。按结石位置分层，近端、中段和远端的结石清除率分别为 93.3%、67.6%和 94.5%。每位患者的平均治疗次数为 1.14 次。42.5%的患者需要静脉注射酮咯酸或曲马多止痛。未记录到明显的副作用。
新型 Doli S EMSE 220F-XXP 在处理输尿管结石时，与 Doli S EMSE 220 具有相似的安全性和无重大并发症的特点；对于远端结石，结石粉碎的改善尤其明显，可大大增加脉冲数和治疗强度，并广泛应用设备升级后的功率。
