Abstract
CHAVEZ LOYA, Manuel Atocha; LOZANO ZALCE, Horacio and RODRIGUEZ WYLER LOPEZ, Octavio. Ureteropelvic junction (UPJ) obstruction. Acta méd. Grupo Ángeles [online]. 2021, vol.19, n.4, pp.544-546. Epub Aug 01, 2022. ISSN 1870-7203. https://doi.org/10.35366/102543.
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.
Keywords : Ureteropelvic junction obstruction (UPJ); pelvocaliectasis.
