目的:分析影响改良侧卧位经皮肾取石术手术时间的因素。方法:收集2005~2012年由同一位医生行PCNL治疗肾结石233例病例资料,比较性别、年龄、结石大小、结石类型、结石位置、是否行EWSL、穿刺通道数量、是否合并肾积水以及外科手术经验等因素对手术时间的影响。结果:所有病例平均手术时间(91.1±36.3)min。性别、年龄、是否行ESWL对手术时间无影响,结石的大小和手术时间有关(P<0.05),结石的复杂程度、多通道穿刺、是否合并肾积水与手术时间相关,对手术时间的增加有统计学意义(P<0.05)。而手术经验的增加相应的减少手术时间。结论:结石大小、结石位置、结石类型穿刺通道数量、是否合并肾积水、手术经验是影响改良侧卧位经皮肾取石术手术时间的因素。
Objective: To analyze the factors influencing the operation time of percutaneous nephrolithotomy in lateral position. Methods: Data of 233 cases of renal calculi treated by PCNL from the same doctor between 2005 and 2012 were collected. Gender, age, size of stone, type of stone, location of stone, whether EWSL was performed, number of puncture channel, hydronephrosis and surgery Surgical experience and other factors on the operation time. Results: The mean operative time was 91.1 ± 36.3 min in all cases. Gender, age, whether ESWL was performed had no effect on the operation time, the size of the stone was related to the operation time (P <0.05), the complexity of the stone, multi-channel puncture, hydronephrosis and operation time, There was statistical significance (P <0.05). The increase in surgical experience corresponding to reduce the operation time. Conclusion: The size of stones, the location of stones, the number of stone-type puncture channels, and whether hydronephrosis with hydronephrosis are complicated. Surgical experience is a factor that influences the operation time of percutaneous nephrolithotomy in lateral position.
