Hydronephrosis - bilateral
Signs of hydronephrosis are generally seen during pregnancy ultrasound studies. There are no symptoms in the fetus.
In the newborn, any urinary tract infection is reason to suspect some type of obstructive problem in the kidney. An older child who gets repeat urinary tract infections should be evaluated for possible obstruction.
Urinary tract obstruction usually has no other symptoms beyond an increased number of urinary tract infections.
