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.
How would you describe the intravesical lesions in figure 2?
Bilateral vesicoureteral reflux (VUR)
Bilateral pelvi-ureteric junction obstruction
Posterior urethral valves (PUVs)
Which complication(s) may you expect in such cases?
Urinary tract infection (UTI)
Obstructive voiding symptoms
Failure to thrive
All of the above
How would you treat this problem?
