Synchronous nephrectomy with unilateral dual kidney transplantation: feasibility in patients with adult polycystic kidney disease

Adult polycystic kidney disease (APKD) accounts for 2% of end-stage renal disease in Singapore and is a major indication for kidney transplantation. We report synchronous nephrectomy with unilateral cadaveric dual kidney transplantation (DKT) in a patient with APKD. Simple nephrectomy of the right native 27-cm polycystic kidney was performed to provide adequate space for unilateral DKT. Right donor kidney transplantation was performed at the site of native nephrectomy. End-to-side anastomosis of the right donor renal vein to the distal inferior vena cava and the right donor artery to the common iliac artery were performed. Left donor kidney was transplanted below the right kidney, with its vessels anastomosed to the right external iliac vessels. Ureter anastomosis was performed after perfusion of both kidneys. Lich-Gregoir anastomosis of the left donor ureter to the bladder and direct right donor ureter to native ureter anastomosis was established. This case illustrates that synchronous nephrectomy with DKT is feasible to facilitate implantation on the same side.
