Fetal hydronephrosis

Case contributed by Dr Mostafa El-Feky


Routine second trimester scan.

Patient Data

Age: 30 years
Gender: Female

The fetal left kidney is seen enlarged with moderate hydronephrosis and stretched parenchyma. The AP diameter of the renal pelvis measures 15 mm. There is a ballooning of the renal pelvis with no visualized dilated left ureter.

Normal size of the fetal right kidney with no pelvicalyceal dilatation.

Normal urinary bladder.

Case Discussion

This case shows typical example of prominent fetal hydronephrosis. The dilatation doesn't extend to the ureter and the renal pelvis is ballooned, then pelviureteric junction obstruction is suggested. Postnatal renal ultrasound is recommended for follow-up, as this degree of dilatation could make surgical intervention more proposed management.
