Resolution of anuric acute kidney injury after left renal angioplasty and stenting for a totally occlusive in-stent restenosis of a solitary kidney.

The authors report a case of unilateral renal artery in-stent occlusion leading to anuric acute kidney injury in a patient with solitary functional kidney. To their knowledge, this is the first reported case of anuric acute kidney injury, which was successfully treated with percutaneous stenting leading to return of renal function to baseline and a prompt resolution of anuria. This case demonstrates that percutaneous revascularization is a safe and feasible treatment option for in-stent occlusion of renal artery supplying a solitary functional kidney and underscores the importance of early recognition and treatment.
