Neonatal renal cystic diseases.

<bold>Purpose: </bold>Neonatal renal cystic diseases have a great impact on the morbidity and mortality of the affected neonates and infants. A good insight into the pathophysiology, diagnosis and treatment options of various neonatal renal cystic diseases aid in early diagnosis and intervention, thereby preventing complications.<bold>Methods: </bold>PubMed search was done for articles on "neonatal renal cystic diseases" and relevant publications including reviews were considered for our article.<bold>Results: </bold>Both hereditary and nonhereditary causes of cystic kidney diseases can result in severe morbidity and mortality. The main diagnostic modality is ultrasound imaging and most of the neonatal renal cystic diseases are detected during prenatal ultrasound screening. Commonly encountered neonatal renal cystic diseases are autosomal dominant polycystic kidney disease, autosomal recessive polycystic kidney disease and multicystic dysplastic kidney.<bold>Conclusions: </bold>A thorough knowledge of various renal cystic diseases can be of extreme prognostic value. Physicians should be aware of the impact of early diagnosis and intervention on the lives of those affected. Further research about treatment of these diseases is ongoing and can result in breakthrough therapies for these patients. [ABSTRACT FROM AUTHOR]
