Hand-assisted laparoscopic live donor nephrectomy in a patient with renal artery aneurysm

Among the transplantation teams there is an increasing interest in laparoscopic live donor nephrectomy. For technical reasons, the use of the left kidney is recommended. However, considering the shortage of organ donors, it is likely that right-side laparoscopic live donor nephrectomy will need to be considered in selected donors, even those with vascular anomalies. Here we report the first case of right-side live donor laparoscopic nephrectomy in a patient with a renal artery aneurysm. Arteriography showed a 3-cm saccular aneurysm of the main right renal artery located at the bifurcation of the secondary branches and associated with an inferior polar artery coming directly from the aorta. The patient was placed in the lumbotomy position. An 8-cm midline incision was made above the umbilicus to insert the HandPort system (Smith & Nephew S.A., 72019 Le Mans Cedex2, France). Four additional trocars were introduced. Dissection of the renal artery was carried out beyond the level of relieving the aneurysm behind the vena cava. The main and polar arteries were clipped, and the renal vein was stapled. The kidney was removed through the HandPort and perfused cold ex vivo. The warm ischemia time for the kidney was 1 min, and the total operative time was 280 min. Vascular abnomalies were corrected ex vivo. The postoperative course of the donor was uneventful. At 6 months after transplantation, the graft function was normal. The hand-assisted approach is of particular value on the right side where the dissection must be carried out behind the vena cava. The HandPort may save few precious minutes over the sac extraction technique of the standard laparoscopic procedure.
