Vascular reconstruction in urology.

Vascular reconstructive surgery in urology includes techniques of revascularization of the renal artery for renovascular hypertension or ischemic nephropathy in situ or extracorporeal renal artery reconstruction. The indications for aortorenal bypass, extra-anatomic bypass, or simultaneous aortic substitution and renal revascularization are based on the cause, location, and extent of the vascular lesion. Techniques of bench surgery mainly depend on location of the renal artery disease and availability of autologous graft material.
