In brief: Many things

Kidney failure can be from problems before, within and after the kidneys(pre-, intrinsic, post-renal failure).
Dehydration or poor blood flow from heart problems, blockage from prostate or urinary flow problems, and many things within the kidney. Infection can do it, too. Diseases such as diabetes and hypertension are main causes, as are medications.
