【摘要】 背景:大鼠肾移植模型是器官移植和肾脏相关疾病研究中常用的动物模型,目前已有多种建模方式,但这些模型在移植时间、移植效果等方面都存在各种问题。目的:拟建立一种简便、安全、成功率高的单侧供肾大鼠肾移植模型。设计、时间及地点:动物模型分析实验,于2008-03/06在复旦大学泌尿外科研究所完成。材料:Wistar大鼠作供体,SD大鼠作为受体,各60只。方法:切取供体左侧肾脏作为供肾,分别以供体腹主动脉、左肾静脉与受体腹主动脉、下腔静脉端侧吻合,供肾输尿管以5-0带针线牵引插入膀胱,吻合缝针破口完成尿路重建。肾包膜下切除受体原有双肾。统计移植时间和移植成功率。主要观察指标:移植时间、热缺血时间、冷缺血时间、动静脉吻合和尿路重建时间、移植失败率及原因、受体大鼠存活率。结果:手术时间100～140min。其中供肾热缺血时间8～10s,冷缺血时间40～60min。移植成功率为85%,失败原因分别为吻合口狭窄伴血栓6.67%、吻合口出血5%,感染1.67%,不明原因1.67%。结论:实验建立的建模方法简便、可靠,明显缩短热缺血及尿路重建的时间,减少相关并发症。更多还原

【Abstract】 BACKGROUND: Rats model of kidney transplantation are common used in the research of organ transplantation and kidney associated diseases. However,the existed modeling methods have various problems in transplanting time or transplantation effect. OBJECTIVE: To establish a lateral kidney transplantation model with simplity,safty,and high success rate. DESIGN,TIME AND SETTING: The analysis experiment of animal model was performed at the Department of Urology,Fudan University between March and June,2008. MATERIALS: 60 Wistar rats and 60 Sprague Dawley rats were selected as donors and recipients,respectively. METHODS: The left kidney graft was transplanted heterotopically into the left infrarenal position,to perform donor abdominal aorta and left renal vein end-to-side anastomoses to the recipient abdominal aorta and inferior vena cava. The ureter of kidney allograft was inserted into bladder traced by 5-0 needle. Bilateral native kidneys nephrectomy of the recipient was performed immediately. The operation time and survival rate were measured. MAIN OUTCOME MEASURES: Transplanting time,warm ischemia time,cold ischemia time,arteriovenous anastomosis and operation time,graft failure rate and reason,survival rates. RESULTS: The operation cost 100-140 minutes. The warm ischemia time was about 8-10 seconds,while the cold ischemia time was 40-60 minutes. Operation achievement ratio is 85%. Reasons of failures were analysed as follows: stenosis of the anastomotic stoma and thrombosis (6.67%),hemorrhage of the anastomotic stoma (5%),infection (1.67%),and unknown reason (1.67%). CONCLUSION: The establish method with advantages of convenience and reliability,which can notably shortened time of warm ischemia of the graft and urinary tract reconstruction and decreased complications.更多还原
