Congenital anomalies concerning the kidneys and urinary tract represent a heterogeneous group of defects and the main cause of renal failure during childhood. Kidney hypoplasia is one such defect; it is defined in clinical practice as a kidney which is significantly shorter than normal but retains a normal shape and some of its function. Bilateral congenital kidney hypoplasia (BCKH) is 7 times less more frequent than unilateral hypoplasia, thus being one of the rarest anomalies of the kidney and urinary tract. The presence of BCKH in more than one family member is even rarer. This article deals with two male brothers having BCKH diagnosed through ultrasonography of the kidneys and urinary tract. A postnatal diagnosis was made for both of them; the younger brother received his diagnosis when he was 4 years old after being studied for the persistence of low height for his age and the older brother received his at 8 years of age after decreased renal function was revealed during hospitalisation. Ultrasonography study showed reduced size for both kidneys in both cases, according to Hodson's index. This article discusses aspects concerning this congenital anomaly and highlights this disorder's importance in some clinical scenarios. It is hoped that this information may be of use during the initial approach to the family of a BCRH patient.
