Abstract:
This study was to evaluate the value of dual-source CT in the preoperative assessment of living donor kidneys. We collected fifty-five consecutive living kidney donors (male 35, female 20, average age, 39 years old), and performed dual-source CT scan. The plain scan, pre-enhanced arterial phase and venous phase examinations were performed, with the scan level ranged from the 11th thoracic vertebral body to the iliac crest. All the basic images were reconstructed using volume rendering(VR), maximum intensity projection (MIP), multi-planar reconstruction (MPR) techniques to evaluate the anatomical location and variation of renal arteries and veins, and the morphology and function of kidney and urinary tract. All the 55 cases were successful, with completion of CT scan and clear images. 46 cases among the all cases had normal renal arteries and veins, while 6 cases had accessory arteries, 2 cases had pre-hilar renal artery branching, and 1 case had vein variation. For the renal parenchymas, 48 cases were normal, while 2 cases had angiomyolipoma and 5 cases had cortical cyst. There were no variation and disease in upper urinary tract. Compared with the surgical findings, the diagnostic accuracy was 100% with dual-source CT. In conclusion, the dual-source CT can accurately evaluate the vessel of kidney, renal parenchyma and upper urinary tract of living renal donors, can provide reliable imaging information for screening of living donor kidney and can help make operation program in living kidney transplantation.
