'''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 and has zero function. <ref>Maria-Gisela Mercado-Deane, James E. Beeson, and Susan D. John. [http://radiographics.rsnajnls.org/cgi/content/abstract/22/6/1429 US of Renal Insufficiency in Neonates.] RadioGraphics 2002 22: 1429-1438.</ref>

==[[Multicystic dysplastic kidney causes|Causes]]==


In the United States, the [[incidence]] of MCDK is estimated to be 1 in every 2400 live births.<ref>http://www.childrensmemorial.org/depts/fetalhealth/Fetal_MCDK.asp </ref>

==[[Multicystic dysplastic kidney epidemiology and demographics|Epidemiology and Demographics]]==


MCDK is usually diagnosed by [[ultrasound]] examination before birth.

* Mass of non-communicating cysts of variable size.
* Unlike severe hydronephrosis, in which the largest cystic structure (the renal pelvis) lies in a central location and is surrounded by dilated calices, in multicystic dysplastic kidney the cyst distribution shows no recognizable pattern.
* Dysplastic, echogenic parenchyma may be visible between the cysts, but no normal renal parenchyma is seen.

==Treatment==
MCDK is not treatable. However, the patient is observed periodically for the first few years during which ultrasounds are generally taken to ensure the healthy kidney is functioning properly and that the unhealthy kidney is not causing adverse effects.
