经皮肾镜取石术治疗37例复杂肾结石的临床分析

目的探讨经皮肾镜碎石取石术治疗复杂性肾结石的方法及疗效。方法回顾性分析37例经皮肾镜取石术治疗的复杂性肾结石患者的临床资料。其中单用超声碎石22例，联合气压弹道碎石15例。结果37例复杂性肾结石患者的手术时间较长为90～200min，平均130min。单用超声碎石患者中，6例术后有结石残留，约27．27％：联合气压弹道碎石患者中，仅2例术后有小结石残留，约13．33％，经原通道二次碎石取石后，全部取净。平均住院时间为9．5d。随访1～12个月，未发现并发症。结论经皮肾镜碎石取石术处理复杂性肾结石，具有创伤小、恢复快、并发症少、安全清除结石效率高、可重复的优点，是治疗肾脏复杂性结石的较好方法。

Clinical analysis of percutaneous nephrolithotomy in the treatment of 37 cases with complex renal calculi

Objective To investigate the methods and efficacy of percutaneous nephrolithotomy （PCNL） in the treat- ment of complex renal calculi. Methods Clinical data of 37 cases with percutaneous nephrolithotomy for treatment of complex renal calculi were analyzed retrospectively, including 22 cases of ultrasound lithotripsy and 16 cases of com- bining pneumatic and ultrasound lithotripsy. Results The operative time of 37 cases were 90-200 minutes, the mean was 130 minutes. The rate of residual tones was 27.27% in the ultrasound lithotripsy, and 13.33% in the combining pneumatic and ultrasound lithotripsy, but cured in the second lithotripsy. The average hospitalization Was 9.5 days. No complications occurred during 1 to 12 months follow-up. Conclusion PCNL has advantages of little trauma, fast recov- ery, few complication, less complications, safe, high cleaning rate and repeat. PCNL may be a good method for treating complex renal calculi.
