常温下肾动脉阻断后缺血时间与术肾泌尿功能恢复的相关性

Correlation between ischemia time after renal artery occlusion at normal temperature and recovery of urinary function of the kidney

目的:探讨常温下肾动脉阻断后缺血时间与术肾泌尿功能恢复的相关性。方法:选取84例常温下行肾动脉阻断术的患者作为研究对象,其中44例的肾动脉阻断时间<20 min(A组),40例的肾动脉阻断时间≥20 min(B组),对比两组患者的肾泌尿功能恢复情况。结果:A组的术肾泌尿功能恢复时间均明显短于B组(P<0.05);A组孤立肾患者术后1年内无1例发生肾功能不全,B组孤立肾患者术后1年内有3例发生肾功能不全,肾功能不全发生率为25.00%,组间比较差异有统计学意义(P<0.05);A组、B组合并糖尿病、高血压患者的术肾泌尿功能恢复时间均显著高于未合并糖尿病、高血压者(P<0.05);A、B两组行开腹手术和腹腔镜手术者的泌尿功能恢复时间,组内比较差异无统计学意义(P>0.05);但B组开腹手术者和腹腔镜手术者的泌尿功能恢复时间均明显长于A组(P<0.05)。结论:在肾动脉阻断手术中,肾阻断缺血时间越短对泌尿功能的恢复越有利,同时还能减少远期肾功能不全的发生风险。

Objective: To discuss correlation between ischemia time after renal artery occlusion at normal temperature and recoveryof urinary function of the kidney. Methods:84 cases of patients with renal artery occlusion under normal temperature were selectedas the study objects, 44 cases of patients with renal artery occlusion time < 20 min( Group A) , 40 cases of patients with renalartery occlusion time ^ 2 0 min (Group B) , recovery of urinary function of kidney of patients of two groups were compared. Results: Therecovery time of urinary function of the kidney of patients of group A was significantly shorter than that of patients of group B (P < 0.05 ) ; There was no 1 case of patient with renal dysfunction of solitary kidney patients of group A within 1 year after operation, therewere 3 cases of patients with renal dysfunction of solitary kidney patients of group B within 1 year after operation, the incidence of renaldysfunction was 25. 00% , the difference had statistical significance between comparison of groups(P <0. 05) ; Recovery time of urinaryfunction of the kidney of combinated diabetes, hypertension patients of group A , and group B were significantly higher than those ofthe patients without combinated and diabetes, hypertension (P < 0 .0 5 ) ; The recovery time of urinary function of patients of group Aand group B who were treated with laparotomy surgery and laparoscopic surgery, there were no significant differences between twogroups ( P > 0. 05 ) ; But the recovery time of urinary function of patients of group B with laparotomy surgery and laparoscopic surgerywas significantly longer than that of patients of group A (P <0. 0 5 ). Conclusion:In renal artery occlusion surgery, renal ischemia timeis shorter and the recovery of urinary function is more helpful, at the same time, it can reduce the risk of long-term renal failure.
