<s>[INST] both kidneys are small in size and shows lobulated contours parenchymal texture notrmal cortico medullary differentiation well maintained. sir may know is there any serious problem because the size of the kidney reduced by 1.5 cms in 10 days my mothers age is 82 years [/INST] HelloGenerally kidneys become small due to chronic renal disease resulting form chronic hypertension, diabetes mellitus etc. Since cortico-medullary differentiation is well maintained, I don't think kidney size is a matter of concern. Difference of 1.5 cm in 10 days may be due to technical error. It is not expected to decrease without any systemic illness. She may need complete renal function test(RFT). If RFT is fine then it is not a matter of concern. Take Care Chat Doctor.  </s>
