目的建立更简便的小鼠肾移植模型,方便术者快速掌握此技术.方法采用C57BL/6小鼠行20例同种同体异位肾移植,将供体连接肾动脉的腹主动脉袖套和肾静脉分别与受体腹主动脉及下腔静脉行端侧吻合,每侧壁缝针数分别为2～3针及4～6针,线尾不用打结.输尿管重建采用改良法将供体输尿管末端游离于膀胱内加外固定.结果总手术时间为(45.1±3.5)min,首次手术成功率为95%,模型成功率85%,术后观察12周,血清肌酐水平平稳正常,体重增加,肾组织学无明显异常.结论该模型简单易行,容易控制吻合口大小防止吻合口血栓及出血,是理想的手术模型.

Objective To establish a model of kidney transplantation in mice more convenient. Methods Twenty C57BL/6 mice were used for kidney isografts. The end-to-side anastomosis was per-formed between the donor aortic cuff with renal artery and recipient aorta of abdomen, and the donor renal vein and recipient IVC. 2-3 stitches and 4-6 stitches were required for each side' s anastomosis. It didn't need to be tied at the end of the suture. The construct of ureter was modified with joining the donor ureter to the recipient bladder. Results Total operative time was (45.1±3.5) min. The success rate was 95%. All mice were observed for 12 weeks after operation. Serum creatinine level was in normal range. Body weight gain was observed. Renal histology was normal. Conclusion This model is easy and conven- ient. The anastomosis can be controlled to prevent thrombosis and bleeding. It is an ideal model.
