Physical examination during admission found skin edema, tense distended abdomen with an indwelling abdominal catheter, and tachypnea on mechanical ventilation (Figure 1).
This broken line graph shows the variation of the blood urea and creatinine during the hospital and follow-up. DOL: Day of life; US: ultrasound; VCUG: Voiding cystourethrogram.

Voiding cystourethrogram (VCUG) was performed on day 18 after birth on the urologist's recommendation, showing a small circular defect of the anterior urethra and obstructive lesion of the anterior urethra (Figure 3).
The endoscopic view showing a cusp-like valve as the distal structure of the diverticulum in the anterior urethra, the arrow points to the diverticulum in the 6 o'clock position of the urethra.
