Percutaneous stent-in-stent placement for renal artery stenosis of a solitary functioning kidney.

In-stent thrombosis is an infrequent complication and necessitates the need to follow-up these patients with renal artery stents. We present here a young individual who presented with in-stent thrombosis in a solitary functioning kidney and was successfully treated with stent-in-stent placement.
