When patients have renal tubular injury how long can they recover, it mainly depends on the cause of renal tubular injury, if the renal tubular is a lack of blood volume leading to epithelial cell detachment, timely infusion of blood treatment, 1-2 weeks later can recover on their own, in about 3-4 weeks the kidney function can be restored to normal. If the patient’s renal tubular injury is caused by toxic factors or immune factors, it cannot be recovered because it is more difficult to remove and will keep damaging the renal tubules, causing complete necrosis as well as fibrosis. How long a patient can recover from renal tubular injury is determined by the cause and severity of the injury, and if the damage is severe, it cannot be recovered.
