Mild kidney injury in young people may be caused by diseases such as glomerulonephritis, pyelonephritis, acute interstitial nephritis, etc. If patients are treated in time, most of them can recover. However, if patients are not treated in time, they may not recover. 1. Glomerulonephritis: If young people have glomerulonephritis, which causes mild damage to the kidneys, they should use drugs such as prednisone and cyclophosphamide under the guidance of doctors in time. Most of the patients are likely to recover with timely treatment, but a few of them may deteriorate. 2. Pyelonephritis: If patients suffer from mild kidney injury due to pyelonephritis, antibiotics such as cefuroxime and cefixime should be used under the guidance of doctors. Patients can generally recover after taking measures to treat the condition as prescribed by the doctor, or they will not recover if they do not take treatment. 3. Acute interstitial nephritis: If acute interstitial nephritis leads to mild renal injury, patients follow the doctor’s instructions to use cyclophosphamide, prednisone acetate and other drugs to treat, generally can recover. However, if the patient is not treated, the condition may worsen and develop into chronic renal failure. It is recommended that young people with mild kidney injury should consult a doctor in a regular hospital in time, so that the doctor can determine whether the condition can be recovered according to the cause of the disease and take standardized treatment.
