Hi!
I am sorry to hear about this. Probably the growing baby has fetal hydronephrosis (dilatation of kidney). What is good news is that in a good percentage of cases the hydronephrosis disappears after baby's birth. The cause of obstruction is difficult to diagnose by ultrasound when the baby is in mother's womb and can only be diagnosed after birth if it persists. The various other causes are obstruction to ureteropelvic junction, vesicoureteral reflux (urine refluxes back from bladder towards kidney), megaureter or a large ureter, or posterior urethral valves. Do discuss this with a pediatric nephrologist. Take care!
