Could a difference in the kidney size indicate a problem?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

My mother is 55 years old, and her kidney sizes have been measured as follows: the right kidney is 95 millimeters, and the left kidney is 111 millimeters. Despite her normal blood tests, I am concerned about the noticeable difference in size between the two kidneys. Is this normal, or could there be an underlying issue?

Kindly help.

Hello,

Welcome to icliniq.com.

I understand your concern.

Your mother, aged 50, is in good overall condition according to the ultrasound (USG) report (attachment removed to protect the patient’s identity), except for a kidney-related issue. The report indicates that it is normal for most people to have a slight size difference between the left and right kidneys, with one being slightly larger than the other, which is not a cause for concern. It also mentions a small three-millimeter kidney stone in the right kidney, referred to as a concretion. Additionally, your mother may have had a stone in the left kidney at some point, which could have passed, leading to a slightly larger left kidney. Alternatively, her left kidney might be slightly bigger than the right. To address the kidney stone, it is recommended that she drinks plenty of fluids, around three to four liters of water per day, which can help flush it out. It is also advisable to consult her regular physician, who can prescribe syrup to help dissolve the kidney stone. Lastly, the report did not mention her uterus. If it was removed through surgery (hysterectomy), inform the sonographer so they can note it as a post-hysterectomy status. If it is not removed, you should ask the sonographer why they did not comment on the uterus.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.

Thank you.
