Hello Thanks for writing to HCM Your baby is suffering from mild hydronephrosis in right kidney.This condition is also called as pyelectasis in which there is mild dilatation of fetal renal pelvis in AP diameter. It is the most common fetal abnormality detected on prenatal ultrasound examination. You need follow up scan.In majority of the case it resolves with the progression of pregnancy .It is important to know about the amount of amniotic fluid. If dilatation of renal pelvis persists,then it can be managed even after birth. Baby may need antibiotics and few investigations.Since there is only mild dilatation,we can expect better results.Let s hope for the best. Hope i have answered your query. Get well soon.
