Transplante renal artery stenosis (TRAS) is defined as renal artery diameter reduction of more than 50%, which causes a reduction in glomerular filtration rate and a rise in plasma creatinine concentration. Current treatments are endovascularballoon-angioplasty and stent implantation. We present the case with renal artery stenosis and ascites was treated with endovascular-balloon-dilatation. A 52-yearold female patient who was admitted to the nephrology clinic five months after the transplantation with blood pressure: 180/110 mmHg, ascites, and the chest radiograph did not show a pulmonary oedema, creatinine: 1.69 mg/dL other laboratory tests were normal. An occlusion of 80 % in a segment and the stenosis was reduced to 10 % by endovascular-balloon dilation. Following endovascular-balloon dilation, arterial blood pressure were normal and no ascites. Endovascular balloon dilation is minimally invasive method that is also successful, contemporary and valid procedures with easy applicability for the management of TRAS.
