压电晶体碎石机治疗不同部位输尿管结石疗效分析

目的：评价压电晶体碎石机治疗不同部位输尿管结石的效果分析。方法：对1989～2010年ESWL治疗的泌尿系结石49172例，其中输尿管结石37629例（右输尿管上段结石7716例，右输尿管中段结石4178例，右输尿管下段结石7111例，左输尿管上段结石9142例，左输尿管中段结石1712例，左输尿管下段结石7770例）进行回顾性分析，碎石后2周行超声及腹部x线平片检查及临床随访。结果：右输尿管上段结石一次排净率为72．71％，右输尿管中段结石一次排净率为73．21％，右输尿管下段结石一次排净率为80．91％，左输尿管上段结石一次排净率为74．17％，左输尿管中段结石一次排净率为73．89％，左输尿管下段结石一次排净率为82．48％。结论：单纯B超定位ESWL是一种治疗输尿管结石的理想方法，排石率高，不受阴性结石影响，具有操作简便、安全、痛苦少、无x线伤害、效果满意、并发症少等优点，是输尿管结石的首选治疗方法。

To Evaluate the Effect of Piezoelectric Lithotripter in Treating Different Parts of the Ureteral Calculi

Objective：To evaluate the effect of Piezoelectric Lithotripter in treating different parts of the ureteral calculi. Methods：The 37 629 cases（the right upper ureterie calculi 7 716 cases,mid ureteric calculi 4 178 cases, lower ureterie calculi 7 111 cases,the left upper ureteric calculi 9 142 cases,mid ureterie calculi 1 712 cases,lower ureteric calculi 7 770 cases）ureteric-calculi patients who applied ESWL from 1989 to 2010 were retrospectively analysis,after ESWL 2 week we took ultrasonic examination and X-ray film inspection and clinical follow-up visit. Results：The clearance rate of the right upper ureteric calculi was 72.71%, the clearance rate of mid ureteric calculi was 73.21%, the clearance rate of lower ureteric calculi was 80.91%, The clearance rate of the left upper ureteric calculi was 74.17% ,the clearance rate of mid ureteric calculi was 73.89%,the clearance rate of lower ureteric calculi was 82.48 %. Conclusions：This method is an ideal treatment for ureteral calculi,it has many advantages such as the higher clearance rate of ureteric calculi, no negative stone effect, simple operation, no x-ray injury, safe, few distress, satisfying effect, few complication etc. ,and it is the first choice for ureteral calculi.
