title: Bilateral hydroureters and hydronephrosis in a neonate.
abstract: : A newborn boy was diagnosed antenatally with bilateral hydronephrosis. Postnatal renal ultrasound scan (USS) measured a renal pelvic anteroposterior diameter (APD) of 12 mm on the left side and 7 mm on the right side. The baby had good urine stream. Parents missed the repeat USS at the age of 1 week. An ultrasound done at 4 weeks revealed progressive hydronephrosis, bilateral hydroureters, with increased renal echogenicity. Normal bladder wall thickness was noted but two intravesical lesions were seen (figures 1 and 2). The APD was 13.5 and 11 mm on the left and right side, respectively.edpract;103/1/20/EDPRACT2016311091F1F1EDPRACT2016311091F1Figure 1Renal ultrasound scan of (A) left kidney (LT) and (B) right kidney (RT) showing bilateral hydronephrosis (white arrows) and hydroureters (red arrow).
