目的研究大动物活体肾移植的外科技术。方法应用氯胺胴、安定静脉麻醉,游离供体左肾动、静脉及输尿管,切取左肾,离体灌注后备用。游离受体腹主动脉、下腔静脉。将供肾动、静脉分别与受体腹主动脉、下腔静脉作端侧吻合,供体输尿管与受体膀胱吻合后单J管从腹壁引出作外引流。结果22头幼猪共完成15例次活体肾移植手术。移植肾冷缺血时间为35～70min,血管吻合时间为28～52min。手术中死亡3例,其中2例(供、受体各1例)死于麻醉过深,1例死于肺动脉血栓栓塞。出现输尿管膀胱吻合口尿瘘1例,输尿管狭窄1例。结论娴熟的外科技术和良好的人员配合是大动物活体肾移植成功的基础,是减少术后并发症的关键。
Objective To study the surgical techniques of living kidney transplantation in large animals. Methods Chloramine carnitine, stable intravenous anesthesia, free donor left renal artery, vein and ureter, left kidney, perfusion after standby. Free receptor abdominal aorta, inferior vena cava. Will be for the renal artery and vein respectively with the recipient abdominal aorta, inferior vena cava for end to end anastomosis, the donor ureter and recipient anastomosis after a single J tube from the abdominal wall for external drainage. Results Twenty-two young pigs completed 15 cases of live kidney transplantation. Transplantation of kidney cold ischemia time is 35 ~ 70min, vascular anastomosis time is 28 ~ 52min. Three patients died of surgery, two of them (one donor and one recipient) died of deep anesthesia and one died of pulmonary thromboembolism. Urinary fistula occurred in 1 case of urinary fistula, ureteral stricture in 1 case. Conclusion Skillful surgical techniques and good staffing are the basis of the success of living animal kidney transplantation and the key to reduce the postoperative complications.
