The kidney transplantation procedure is relatively complex and only a brief statement of the general steps can be made: 1. The kidney provided by the donor kidney is cleaned, excess fatty tissue is removed, and the vessels and ureters are trimmed to maintain a certain length and a certain caliber to facilitate anastomosis. In case the donor kidney has multiple vessels, the fusion of multiple vessels into a single vessel is performed if necessary to facilitate the anastomosis during surgery.2. The donor is anesthetized by general or hemi-body anesthesia, and a curved incision is made in the right iliac fossa to reveal the internal iliac vein and internal iliac artery.3. The artery and vein of the donor kidney are anastomosed over the internal and external iliac veins and arteries of the recipient, at which point the vessels are opened and observed for blood leakage from the anastomosis. If there is blood leakage, add stitches appropriately. When the blood flow is restored, the donor kidney starts to work, which is then seen to be congested and red and starts to produce urine. If good blood flow of the donor kidney is seen, the ureter of the donor kidney is planted on the top of the patient’s bladder and a ureteral stent tube is left in it, which will be removed at an optional time 1-3 months after surgery.4. Observe the kidney if there is no sign of ischemic necrosis when blood flow is restored and the patient can produce continuous urine volume, it indicates that the kidney has been successfully anastomosed and the operation can be ended and wait for the recovery of kidney function at a later stage.
