摘　　要：目的比较经皮肾镜术大小通道出血量。方法采用离体的生理盐水持续灌注的猪肾脏模型。在猪肾上建立穿刺通道后，先后建立16、18、22、24、30F5组通道，每组10个通道，分别测量失血量。结果5组通道的出血量分别为（5．84±0．98）、（5．99±0．85）、（9．76±1．05）、（11．90±t．49）、（14．48±1．30）g/min，通道越大，出血量越多，差异有统计学意义（P〈0．05）。16F与18F通道出血量之间比较差异无统计学意义（P〉0．05）。结论在经皮肾镜手术中，通道越大，出血量越多，小通道经皮肾镜术可减少术中出血量。Objective To compare the blood loss 1of different size of nephrostomy tracts in percutaneous nephrolithotomy （PCNL）. Methods The model of isolated normal saline （NS）-perfused porcine kidney was used to determine the blood loss of different size of nephrostomy tracts. By applying the technique of percutaneous nephrostomy, five groups of different size of nephrostomy tracts （ 16, 18, 22, 24, 30 F） were established on the porcine kidney gradually, with 10 tracts in every group, then the blood loss of each group was measured respectively. Results The blood loss of the five tracts （ 16, 18, 22, 24, 3OF） was （5.84±0.98）, （5.99±0.85）, （9.76±1.05）, （11.90±1.49）, （14.48±1.30） g/min, respectively. The blood loss was increased with the size of the tract diameter （ P 〈 0. 05 ）. There was no significant difference between 16 F and 18 F groups （ P 〉 0. 05 ）. Conclusion The blood loss of PCNL was increased with the size of the nephrostomy tracts. Mini-PCNL could cause less bleeding than standard-PCNL.
