are small kidneys in children damaging?

Question:

my daughter (5 years) had a recent ultra sound because of recurring UTI's and they found her kidneys are half the size they should be. Is this damaging? what is the medical term? what are the implications for the future? I'm now waiting for appointment with specialist.

Answers:
Hi, hope this helps answer your question.

The medical name for small kidneys is ‘congenital dysplasia’

In some people both kidneys can be affected by congenital dysplasia, and there may be kidney failure. The small kidney may be in a normal position in the upper back, or may have failed to move up from the lower abdomen before birth. A kidney in the lower abdomen is called a pelvic kidney. Many pelvic kidneys have normal function, but in some people a pelvic kidney can be small or have abnormalities in the drainage system, giving a risk of recurrent infection.
The kidney is damaged because of a faulty drainage system, usually a condition called reflux nephropathy. This is a common cause of a small kidney detected in childhood or in a young adult. Reflux nephropathy can affect both kidneys. More information on reflux nephropathy is available from the NKF.
