Multiple renal arteries with renal cell carcinoma: preoperative evaluation using computed tomography angiography prior to laparoscopic nephrectomy.

Objective: To investigate anatomical variations in the renal arteries of patients with renal cell carcinoma (RCC) using computed tomography angiography (CTA).

Methods: Patients diagnosed with RCC were evaluated using CTA prior to undergoing laparoscopic nephrectomy. Any anatomical variations of the renal arteries on the side affected by the RCC were recorded.
