I also finished Evenity and have advanced to Prolia for 3 injections and then reclast . The reason behind going to Prolia is to add more bone density. Reclast adds no bone density just locks in the gains.
The only thing you would have to be aware of since you have mild kidney disease, your doctor should closely monitor your calcium levels while you are on Prolia or reclast. I know I had to up my calcium intake.
