What causes enlarged kidney?
Patient: Hello. Roughly 3 years ago I was in an accident and had a battery of tests done at the hospital. The only thing that was said is that on my x-ray it showed an enlarged kidney, but that was told to me by the doctor in passing as I was laying on the gerny in the hallway. Ive had blood work (yearly) and urine tests since then for physicals and nothing out of the ordinary has ever been mentioned. Im at a point in my life where Im fully enjoying it and want to get it checked out so I had an ultrasound earlier this year. Can there be anything that could come of this if it was years ago it was mentioned an nothing has shown up on recent tests. On the ultrasound (done in January 2014) nothing was shown either. And I specifically asked about it being enlarged. At times I get sore in my back side by kidneys and start to worry. Maybe just being nervous and I don t want anything to happen to me for a long long time. Doctor: Hi,Thanks for writing in.A normal kidney size measures 80 to 120 mm in length with the difference in length between two kidneys being not more than 20 mm. Therefore of your kidney is within this range then it is not a serious concern.There are patients in who one particular kidney might be larger than usual because of hypertrophy. This is only an increase in size and does not mean the kidney is under any type of stress or is diseased; this is an acceptable normal variant condition.If your blood tests for kidney function are normal and no significant abnormality is noted then your kidney is not a concern. Please do not worry.
