Renal hypoplasia is a congenital abnormality in which one or both of the kidneys are smaller than normal, [5] resulting in a reduced nephron number [1] but with normal morphology. [ 4 ] It is defined as abnormally small kidneys, where the size is less than two standard deviations below the expected mean for the corresponding demographics , and ...
Generally, diseases outlined within the ICD-10 codes Q60-Q64 within Chapter XVII: Congenital malformations, deformations and chromosomal abnormalities should be included in this category. Wikimedia Commons has media related to Congenital diseases and disorders of urinary system .
Renal agenesis is a medical condition in which one (unilateral) or both (bilateral) fetal kidneys fail to develop. Unilateral and bilateral renal agenesis in humans, mice and zebra fish has been linked to mutations in the gene GREB1L . [ 1 ]
Renal abnormalities in VACTERL association can be severe, with incomplete formation of one or both kidneys or urologic abnormalities such as obstruction of outflow of urine from the kidneys or severe reflux (backflow) of urine into the kidneys from the bladder. These problems can cause kidney failure early in life and may require kidney ...
[3] [4] Removal of the kidneys (one at the time or both) can decrease protein loss and limit the number of albumin infusions needed. [1] [4] Infants with WT1 mutations will undergo bilateral kidney removal to prevent development of Wilms' tumor. [4] Antibiotics may be needed to control infections.
Congenital mesoblastic nephroma, while rare, is the most common kidney neoplasm diagnosed in the first three months of life and accounts for 3-5% of all childhood renal neoplasms. [ 2 ] [ 3 ] It is generally non-aggressive and amenable to surgical removal, though there is a subtype that is more aggressive and tends to spread to other organs .
Autosomal recessive polycystic kidney disease (ARPKD) is the recessive form of polycystic kidney disease. It is associated with a group of congenital fibrocystic syndromes. [ 5 ] Mutations in the PKHD1 (chromosomal locus 6p12.2) cause ARPKD.
Multicystic dysplastic kidney (MCDK) is a condition that results from the malformation of the kidney during fetal development. The kidney consists of irregular cysts of varying sizes. Multicystic dysplastic kidney is a common type of renal cystic disease, and it is a cause of an abdominal mass in infants. [5]
