Background & Objective: Atherosclerosis is considered the principle cause of either native or transplant renal artery stenosis (RAS -TRAS), and as a consequence, of related arterial hypertension (secondary HT) and progressive regression of renal function till renal failure .

Objective: the study lighten up the renal arterial disease, discussing the selection of patients and endo-luminal approaches in treating these lesions, then comparing different international studies.

Methods & Materials: a retrospective study was carried on 17 patients ( 19 arteries) who had renal artery lesion and treated by endovascular approaches between 2010 and 1st quarter of 2015.

Results: our study reveals 2 bilateral lesions.

One female patient had FMD treated by a special balloon.

All other patients were treated by PTA-stenting of their lesions.

Normal arterial pressure values were noted in 13 patients.

2 patients continued to have one anti-hypertensive drug and one patient 2 antihypertensive drugs.

One female was operated of total nephrectomy as a consequence of upper lobe artery stent thrombosis.

Conclusion: we can conclude that endovascular treatment is safe and effective in treating primitive or transplant renal artery lesions.
