Abstract

Aim

The aim of this study was to characterize the morphology of renal tumor vessels.

Methods

Twenty-two patients with kidney neoplasm underwent three-dimensional reconstruction prior to surgery. The vascular cast of kidney specimens was obtained after surgery.

Results

The 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).

Conclusion

Most renal cellular carcinomas are rich blood-supplied tumors with distinctive vasculature in the tumor region.
