Robotic Kidney Transplantation Under Regional Hypothermia.

Abstract

The technique of robotic kidney transplantation (RKT) under regional hypothermia is being described. It may be performed in all patients requiring kidney transplantation with some relative contraindications. Unlike open transplantation, RKT is a transperitoneal procedure. Patient lies supine with low lithotomy and 15° to 20° reverse Trendelenburg position. Port placement is like standard radical prostatectomy with a multiport device placed at the umbilicus. The graft after harvest needs special care on the bench to ligate all vascular communications and placed in a gauze jacket for easy handling. After transplant bed preparation, the graft is introduced in peritoneal cavity through the umbilical opening and placed over the bladder flap bed with ice slush for hypothermia. End-to-side vascular anastomoses of renal vein and artery are done with the graft lying in pelvic hollow and renal vessels facing laterally to external iliac vessels. After vascular anastomoses, the graft is rotated laterally to iliac fossa to be fixed with preformed peritoneal flap. A stented ureterovesicostomy to the recipient is done using extravesical technique. The external opening for introducing the graft and the robotic port openings is closed after leaving a drain. Postoperative (PO) care and PO immunosuppression are like the open counterpart, except the treatment of drain, which is removed on second PO day. Obese recipients and multiple graft vessels may be handled comfortably during RKT with described techniques. It is important to follow certain checkpoints to avoid bleeding. With graft and patient survival of 95.2% and 94.5%, respectively, RKT outcomes are noninferior to open technique in the published data. The RKT has less incidence of PO pain, wound infection, and symptomatic lymphoceles.
