Renal artery calcifications can be associated with insufficient stent expansion and in-stent restenosis. Intravascular lithotripsy (IVL) uses shockwaves to disrupt calcium and treat calcific renal in-stent restenosis. Herein, the authors present a case to treat resistant reno-vascular hypertension and in-stent restenosis of an inadequately expanded renal stent in a patient with severe calcific renal artery stenosis. The patient was treated with IVL and stent dilation. The patient was followed subsequently, and her home blood pressure was well controlled on anti-hypertensive medications. In conclusion, IVL promises pronounced success in the modification of severely calcified renal artery lesions and can be used to treat renal artery stenosis even in the context of inadequately expanding renal artery stents.
肾脏动脉钙化可导致支架扩张不足和支架内再狭窄。血管内碎石术（IVL）使用冲击波破坏钙并治疗钙化性肾内支架再狭窄。在此，作者报告了一例使用 IVL 和支架扩张治疗严重钙化性肾动脉狭窄患者中未充分扩张的肾支架内再狭窄和难治性肾血管性高血压的病例。患者接受了 IVL 和支架扩张治疗。随后对患者进行了随访，她的家庭血压在抗高血压药物的控制下良好。总之，IVL 有望在严重钙化性肾动脉病变的治疗中取得显著成功，甚至可以在肾动脉支架扩张不足的情况下用于治疗肾动脉狭窄。
