Unilateral renal atrophy is usually incurable. Renal atrophy is closely related to some kidney diseases, such as congenital unilateral renal dysplasia, unilateral chronic pyelonephritis, unilateral renal artery stenosis and other diseases, which need to be actively treated under the guidance of the doctor for the primary disease, but the atrophied kidneys usually cannot be cured. In case of chronic pyelonephritis, antibiotic drugs such as amoxicillin capsules and levofloxacin tablets can be taken for treatment; in case of renal artery stenosis, etc., surgery can be actively carried out. All of the above medications should be used under the guidance of a doctor, avoid self-medication. The patients who found renal atrophy are recommended to go to the regular hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or treatment under the guidance of the doctor.
