Comparison between vascular cast and three-dimensional ultrasonography on tumor vessels

AimThe aim of this study was to characterize the morphology of renal tumor vessels.MethodsTwenty-two patients with kidney neoplasm underwent three-dimensional reconstruction prior to surgery. The vascular cast of kidney specimens was obtained after surgery.ResultsThe vascular cast revealed proliferation, thickening, compression, displacement, and arteriovenous fistulae in tumor vessels, which were consistent with the findings from 3-D ultrasound (χ2=12.60, P<.01).ConclusionMost renal cellular carcinomas are rich blood-supplied tumors with distinctive vasculature in the tumor region.
