Renal dysplasia, bilateral

ORPHA:93173Clinical subtype

Also called Kidney dysplasia, bilateral

What it is

A form of renal dysplasia (RD), a renal tract malformation, characterized by abnormal or incomplete development of both kidneys. Bilateral RD can be segmental, and of variable severity, with renal aplasia corresponding to extreme RD. Patients may be asymptomatic if the residual kidney function is sufficient. In cases of severe bilateral RD, the risk of renal failure in childhood is high.

Q61.4filed under a broader ICD-10 category — shared with 5 other rare diseases

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
