Question
If an infant is found to have renal pelvis separation during pregnancy, does it require follow-up examination after birth?
Answer
If an infant is found to have renal pelvis separation during pregnancy, it is recommended to regularly visit a pediatric hospital for follow-up, including urine tests, kidney function tests, and renal ultrasound examinations, to monitor the condition of the renal pelvis separation and its impact on kidney function. Most mild hydronephrosis will resolve spontaneously during the neonatal period, but regular checks are needed to confirm this. For 15% of cases that require surgery, early intervention should be carried out to restore kidney function and morphology.
