Abstract
We describe a technique of complete intracorporeal renal autotransplantation with donor nephrectomy and transplantation performed in a minimally invasive fashion without extracting the kidney. We developed this technique of a completely intracorporeal robotic renal autotransplantation and determined the feasibility of this novel procedure. This includes a method of intracorporeal transarterial hypothermic renal perfusion using a perfusion catheter through a laparoscopic port. The procedure was successfully applied in a 56-year-old man with extensive left ureteral loss after failed ureteroscopy for ureterolithiasis. Robotic donor nephrectomy was performed with a warm ischemia timeof 2.3 minutes. Subsequently cold ischemia was achieved by intracorporeal hypothermic renal perfusion for 95.5 minutes. Vascular anastomoses and ureteroureterostomy in the ipsilateral pelvis were completed afterdonor nephrectomy with a total overall surgeon console time of 334 minutes. Venous and arterial anastomosis times were 17.3 and 21.3 minutes, respectively. Estimated blood loss was less than 50 ml. There were no complications and the patient wasdischarged home on postoperative day 1 after normal Doppler transplant renal ultrasound. Postoperative renal scan at 6weeks, intravenous urogram at8weeks and computerized tomography urography at5 months revealed normal function and successful ureteral reconstruction. We report the feasibility of a technique of a completely intracorporeal robotic renal autotransplantation. This operation may be considered inselect patients in the hands of experienced robotic surgeons. However, furtherrefinement is required as this novel procedure is cautiously reproduced and adopted by others.
