question: Hi Doc, My dad was diagnosed with UTI and physician asked him to go for ultrasound . His ultrasound results shows that his Right kidney is 91*35mms and Left kidney is 97*40mms. The Report says there is an increase in size of kidneys. Hence the physician asked my dad to consult a Nephrologist . Could you please let me know what could be the cause for this increase in size? and is this increase is normal with age?
