question: my sis has high creatinin level of 111, her left kidney has parenchymal disease and she had a right kidney stone removed from years back though current result proves that her kidney is clear. she wants to know what are the dos and donts and what are the risks for having this high level of creatinin and parenchymal disease, what important things do we need to ask from her doctor if we have her checked up. thanks alot. god bless.
