[Admin]

First one with correct answer with justification win.

A newborn boy has urine draining from the umbilicus. After physical exam there is a clinical diagnosis of a patent urachus that is confirmed by ultrasound. Which of the following untreated associated anomalies is a contraindication to early surgical closure of a patent urachus?

A anorectal malformation with rectourethral fistula

B horseshoe kidney

C myelomeningocele

D posterior urethral valves

E vesicoureteral reflux

D

correct

A patent urachus that is draining urine out the umbilicus is usually excised completely and closed at the level of the bladder. A contraindication to that plan would be a distal urinary tract obstruction such as posterior urethral valves since closing the “pop-off valve” would potentially lead to a urinary tract obstruction.
