Abstract:
Objective To evaluate the condition of living renal donors with 3-dimensional volume rendering computed tomography (3D-CT) in preoperation. Methods 10 consecutive cases received hand-assisted transperitoneal laparoscopic living donor nephrectomy (HLDN) from December 2001 to July. Total patients underwent 3-dimensional volume rendering computed tomography before operation for assessing the condition of the anatomical location, number, anomalies and spatial interrelationships of the renal arteries and veins. These 3D-CT were directly compare with intraoperative surgical findings at laparoscopy and the harvested kidney ex vivo to value the sensitivity and accuracy of 3D-CT. Results The CT digital data of 10 cases were reconstructed to 3D-CT with volume rendering technique, and HLDN were performed successfully in all the cases. The 3D-CT accurately identifies renal vascular anatomy. Conclusions Not only the 3D-CT accurately identifies renal vascular anatomy but also tridimensional images reconstructed by the enhanced CT digital data of arterial phase, venous phase and renal parenchymal phase are viewed by surgeon in any position. It is a manner that may facilitate renal hilar dissection during laparoscopic donor nephrectomy. The 3D-CT should be a routine examination for living donor in preoperation
