case_images: Ultrasound exam of the kidneys, ureters, and bladder (US-KUB) demonstrated mild-to-moderate bilateral hydronephrosis, thickened bladder wall, and dilated distal ureters, suggesting infravesical obstruction or reflux (Figure 1).
case_images: A voiding cystourethrogram (VCUG) revealed a dilated posterior urethra without evidence of vesicoureteral reflux, consistent with a posterior urethral valve initial diagnosis.

case_images: Follow-up results nine months later revealed normal renal function tests; VCUG showed resolution of the previously noted posterior urethral dilatation with no apparent urethral filling defects (Figure 4).
case_images: Ultrasound exam of the kidneys, ureters, and bladder (US-KUB) demonstrated improvement in backpressure changes, although mild hydronephrosis persisted.
