Hydronephrosis is a condition in which the kidney swells and becomes filled with urine in the part of the kidney called the collecting system.
Hydronephrosis can be detected in the fetus during pregnancy, or at any point after birth. Sometimes hydronephrosis can be serious if undetected and untreated but generally it requires no specific treatment except for ultrasound testing and following it on serial ultrasounds.

Symptoms of Hydronephrosis
- Prenatal hydronephrosis, of course, cannot be diagnosed through direct observation of the patient. The doctor must look for signs of the condition on an ultrasound obtained during pregnancy on the mother. An enlarged kidney and any associated abnormalities of the ureters sometimes can be seen in this way.
- After birth, an infant may show fever, nausea, and general failure to thrive. An infection may produce pain in the back over the kidney.
