Recently, during a routine physical examination, it was discovered that my child has congenital renal enlargement requiring surgical treatment. Could you please advise: What is the normal size range for kidneys?

Dr. Yuan Xiaoying
Based on your description, the kidneys are typically 10–12 cm in length, 5–6 cm in width, and 3–5 cm in thickness. Variations in kidney size can occur even under normal physiological conditions. Most importantly, preserving renal function and maintaining normal kidney function is essential. In daily life, drink plenty of water, avoid holding urine, maintain a regular lifestyle, steer clear of spicy and irritating foods, limit intake of sweets, and engage in regular physical exercise—these measures help prevent kidney stone formation.
