Retro- and prospective comparative studies in patients with renal artery stenosis demonstrate that technical results and blood pressure improvement after renovascular surgery or percutaneous transluminal renal angioplasty (PTRA) are strictly comparable. The lesser invasive character of PTRA together with its lower complication rate and the lower cost explain why PTRA is the method of choice in the treatment of renal artery stenosis, with less restrictive selection criteria than used for surgery.
对肾动脉狭窄患者进行的回顾性和前瞻性对照研究表明，血管重建手术或经皮腔内肾血管成形术（PTRA）后的技术效果和血压改善情况具有严格的可比性。PTRA侵入性较小，并发症发生率较低且成本较低，这解释了为什么PTRA是治疗肾动脉狭窄的首选方法，其选择标准比手术的选择标准限制更少。
