经皮肾镜取石术肾实质厚度与术中出血量关系研究

The blood loss is associated with the thickness of renal parenchyma in percutaneous nephrolithotomy

目的：探讨经皮肾镜取石术术中出血量是否与肾实质厚度有关。方法：2013年1月~2015年6月,对符合入选条件的的120例肾结石病人,通过螺旋CT平扫测量目标肾盏的肾实质厚度,按肾实质厚度,分为3组,A组≤15mm,15mm〈B组≤25mm,C组〉25mm。由同一手术医师行经皮肾碎石取石术,测定每例术中出血量,以期得出术中出血量是否与肾实质厚度有关。结果：3组术中出血量分别为（58±18）m L、（30±17）m L、（15±17）m L,出血量C组〉B组〉A组,差异有统计学意义（P〈0.05）。结论：经皮肾镜取石术术中出血量与肾实质厚度有关,肾实质越厚,越容易出血。

Objective：To study whether the blood loss is associated with the thickness of renal parenchyma in percutaneous nephrolithotomy.Methods：From January 2013 to June 2015,120 cases with renal stones were included in our study, the renal parenchyma thickness of target calyces was measured by CT scan, all of the cases were divided into 3 groups according to the thickness of renal parenchyma, group A（〈15 mm）, group B（〉 15mm, 〈 25mm）, group C（〉25mm）.Operation was done by the same surgeon, blood loss intraoperatively was measured. Results The blood loss in three groups was（154-17）mL,（30~ 17）mL,（58：t： 18）mL, respectively. C〉B〉A, the difference was statistically significant （P〈0.05）.Conclusion：The blood loss is associated with the thickness of renal parenchyma in percutaneous nephrolithotomy, thicker renal parenchyma could cause more blood loss.
