"Multicystic dysplastic kidney (MCDK) is a type of non-heritable paediatric cystic renal disease. It results in multiple cysts being formed in utero in the affected kidney. MCDK is the most severe form of cystic renal dysplasia."
"MCDK develops in utero, and the diagnosis is often made either antenatally or in the early neonatal period if an ultrasound is performed. It may otherwise go unrecognised, and may be a common cause of renal agenesis, following complete involution during childhood."
"Multicystic dysplastic kidney is the most common form of cystic renal disease in infants/children, and is one of the most commonly detected anomalies on prenatal ultrasound 9. Unilateral incidence is estimated at 1:2500-4000. There may be a predisposition for the left kidney, a slightly higher incidence in males for unilateral MCDK and a higher incidence in females for bilateral MCDK which is associated with more nonrenal abnormalities."
"MCDK is thought to be due to early severe in utero obstruction 10. A histologic hallmark of MCDK are PAS positive collarettes. The affected kidney (or renal segment) has no functioning renal tissue and is replaced by multiple cysts. Two main types have been described 2:"
"The kidney may be small, normal in size, or enlarged"
