Unlabelled: 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.

The nutcracker phenomenon consists in the compression of the left renal vein by the aortomesenteric clamp. This is an infrequent cause of haematuria. The present paper presents one case of nutcracker phenomenon showing haematuria after mild accidental lumbar bruising, with arteriographic diagnosis. CAT assessment showed a mark in the lumbar ureter as well as peripyelic and periureteral varices.

Renal Vein Thrombosis is an uncommon entity associated to various clinical conditions which develop in hypercoagulant states. The paper describes one case of idiopathic thrombosis of the renal vein in an adult patient, also making a review of the literature on this clinical syndrome and its diagnostic and therapeutic aspects.
