Is it permissible for a pregnant woman who suffers from a single kidney, fibrosis in part of it, and a continuous rise in creatinine, to abort out of fear of her health deteriorating with each pregnancy?

If pregnancy will lead to harm for the one who answers [the question], potentially leading to her demise, then she must strive to prevent it; because preserving life is one of the necessities. Let her wait for the appropriate time for pregnancy, while frequently supplicating, having good expectations, and relying on Allah.
