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.

Figure 1

Renal ultrasound scan of (A) left kidney (LT) and (B) right kidney (RT) showing bilateral hydronephrosis (white arrows) and hydroureters (red arrow). Increased renal echogenicity is not shown in the figure.

Showing normal bladder wall thickness but two intravesical lesions were seen (white arrows).
