A cystic space in the right kidney of an unborn baby suggests the presence of cysts in the kidney, which may be simple renal cysts or polycystic kidneys.
1. Simple renal cysts: simple renal cysts are mostly benign, often isolated, usually do not compress the kidney tissues, and the presence of simple renal cysts in the right kidney will not affect the left kidney, so they can be monitored regularly during pregnancy and after birth. Generally speaking, simple renal cysts have no symptoms, but when the cysts are large, they may cause urinary tract obstruction, hematuria and other symptoms.
2. Polycystic kidney: It is a hereditary kidney disease, and autosomal recessive polycystic kidney disease is common in fetus, which usually occurs in both kidneys. As the disease progresses, the cysts on the kidneys gradually increase in size and number, and eventually cause complications such as renal failure, which can be detected through genetic testing during pregnancy.
Do not be alarmed when cysts appear on the right kidney of the fetus, the doctor will give advice on whether or not to terminate the pregnancy early after full evaluation.
