If the tubular injury is caused by acute factors, we only need to replenish enough calories, maintain water and electrolyte balance, and wait for a period of time, the tubular damage will recover on its own; if the tubular injury is caused by chronic factors, there is no special medicine, but only to avoid these factors that cause tubular injury to prevent further aggravation. Renal tubular injury can be caused by acute factors or by chronic factors. Acute factors are mainly caused by taking large amounts of certain nephrotoxic drugs, such as ibuprofen or rhabdomyolysis, within a short period of time. When these factors are removed, the patient should be given enough calories to improve resistance, maintain water and electrolyte balance, and if necessary, hemodialysis treatment. After a period of time, the patient will basically recover and no special treatment is needed. Chronic tubular injury is mainly caused by long-term application of certain drugs, such as aristolochic acid, anti-inflammatory and analgesic drugs, and long-term poor blood pressure control. In this case, there is no specific drug, but we can only avoid drugs that cause tubular damage and control blood pressure to prevent further aggravation of the disease.
