During the maintenance phase of ARF, urine output is low (less than 500 mL/day) and the urine specific gravity is low because the kidneys are not concentrating urine properly. Hypotension is not typical during this phase, and hypernatremia and epithelial cell casts in the urine are not usually present during the maintenance phase of ARF.
