ABSTRACT
Ureteropyelic junction (UPJ) obstruction is the most common form of urinary tract obstruction in children, it can be diagnosed prenatally or in childhood. Hydronephrosis as a prenatal ultrasound finding is highly suggestive for diagnosis. In infants' symptoms of urinary tract infection are frequent, highlighting intermittent abdominal pain in the flank, hematuria, and fever. This is a newborn male patient, the prenatal ultrasound showed hydronephrosis, a postnatal ultrasound is performed that reveals a marked pyelocaliectasis that ends abruptly at the ureteropyelic junction (UPJ) and the caliber of the distal ureter is normal, a finding that practically confirms the diagnosis in this type of patients, therefore prenatal and postnatal ultrasound is the ideal diagnostic imaging tool.REFERENCES
