The kidney as an apo-exocrine organ has two important functions: the control of homeostasis and arterial blood pressure. Any pathological disorders witch alters the renal blood flow results in two consequences: renovascular hypertension and renal insufficiency. Renal revascularization looks for with priority the improvement of renal function; the good response and control of hypertension shall come after. The goals of this paper is to actualize the sophisticated diagnostic methods (Angiography, Eco-Doppler, AngioCT, AngioMR, Angioscopy; and the use of contrast potential-mediums), functionality tests (RN and MR with Captopril) and management (Percutaneous transluminal angioplasty, simple or covered Stents, Embolizations, Occlusive balloons, Fibrinolysis and Trombus Aspiration; direct Arterial Surgery and renal Autotransplantation) of different renovascular diseases. (Blunt renal injuries, Stenosis, Aneurysms. A-V fistuls, Acute Occlusions or arterial and venous, Thrombosis. Nutcraker Syndrome). The possibility of the presence of an inverse venous Fraley's Syndrome is presented and discussed.
Conclusions: A controversy of the last technical methods are established and discussed and a Guideline is recommended for each renal vascular disease.
