Adjuvant instant preoperative renal artery embolization facilitates the radical nephrectomy and thrombectomy in locally advanced renal cancer with venous thrombus: a retrospective study of 54 cases.

It facilitates nephrectomy and thrombectomy by reducing blood loss, transfusion requirements, and complications of delayed operations, providing urologists with a reliable option for treatment of locally advanced RCC with tumor thrombus.
