There are numerous reasons why fetal kidney enlargement occurs.

1) Vesicoureteral reflux

2) Non-obstructive hydronephrosis

3) Ureteropelvic junction (UPJ) obstruction

4) Ureterocele

5) Posterior urethral valves

6) Ureterovesical junction (UVJ) obstruction

7) Megaureter

8) Multicystic Dysplastic Kidney

9) Ectopic ureter

10) Neurogenic/nonneurogenic bladder
But its also depend on whats the size of kidney and how much is dilatation of renal pelvis
But mostly in mild enlargement you shoul not worry
