Lesion 1 displays the lesion specifics for the first vessel, while lesion 2 is represents the lesion characteristics for those receiving intervention to the contralateral renal artery immediately following successful treatment of the first vessel.

^*The lesion side was not reported in 2.8% of cases.

^**Distal locations are not typical for atherosclerotic lesions and probably represented fibromuscular dysplasia.
