Abstract:
Objective To analyze the clinical value of 16-row multislice CT in the live kidney donor preoperative assessment. Methods Thirty-six kidney donors underwent 16-slice CT preopera-tive assessment. The non-enhanced, arterial phase, venous phase and excretory phase examinations were performed. Two radiologists independently studied renal vessels and urinary system of each case by maximum intensity projections and volume rendering techniques. The specificity and accuracy of 16-row muhislice CT in the evaluation o{ renal vessels and urinary system were calculated after comparing with surgical findings as reference. Results 16-row muhislice CT found 7 variant renal arteries. One variant artery confirmed in surgery was missed in the CT study. 16-row muhislice CT made cor-rect diagnosis of all variant anatomy of renal veins and ureters which were confirmed in surgery. For i-dentification of variant anatomy of renal arteries, veins and ureters, the specificity of 16-slice CT was 100% (29/29), 100% (32/32), and 100% (35/35), the overall accuracy was 97%(36/37), 100% (36/ 36), and 100%(36/36), respectively. Conclusions 16-row muhislice CT shows excellent value in the evaluation of renal vessels and urinary system in live kidney donors. 16-row multislice CT is suit-able for the noninvasive examination in live kidney donor preoperative assessment and provides all sup-portive and relevant information required by the surgeons.
