How Soon After Birth Should a Newborn Undergo Examination?

Question

Key Symptoms of Newborns: During the 32nd week of pregnancy, an ultrasound revealed a renal pelvis separation of 0.7 to 0.8 units in the fetus. When should a newborn go to the hospital for a detailed examination?

Answer

Most newborns who were found to have renal hydrops during pregnancy should undergo a formal urinary system MRI within one week after birth. If the renal pelvis effusion exceeds 10 millimeters (while your baby’s condition is relatively mild), a comprehensive examination under the guidance of a specialist physician is necessary, including renal radionuclide imaging, metabolic cysto-ureterography, etc., to determine the cause. If the renal pelvis effusion is between 4 to 10 millimeters, an MRI follow-up should be conducted at 3 months and 6 months after birth. If the renal pelvis effusion is less than 4 millimeters, it can be considered normal.
