<s>[INST] My 17 year old son had frequently raised blood pressure.He recently has renal ultra sound which reveals bilateral renal parenchymal disease grade 1?.Cortical ecogenicity of both kidneys is slightly increased and corticomedullary differentation is preserved.What all this mean and how it can be treated . [/INST] HelloThanks for choosing HCM. As he is having hypertension there will be effect in his kidneys in which the high Bp will damage the function of the kidneys. Please have regular serum creatinine test done and if there is any increase in that you consult a nephrologist to start the treatment. The most important treatment for him is to maintain his bp. ThanksDr.Alekhya </s>
