What causes vesicoureteral reflux to occur in children?
A)Children do not ask for help in urinating in a timely manner, and urine is forced up into the ureters.
B)The submucosal segment of a child's ureter is short, making the antireflux mechanism inefficient.
C)The trigone lying between the opening to the ureters and the urethra is underdeveloped in children.
D)As the bladder fills in infants and children, it pulls the smooth lining of the transitional epithelium away from the ureters, making the reflux valves ineffective.

Question

Quizplus · Accepted Answer

Although reflux is considered abnormal at any age, the shortness of the submucosal segment of the ureter during infancy and childhood renders the antireflux mechanism relatively inefficient and delicate. Reflux is not due to not voiding in a timely manner, an underdeveloped trigone area, or pulling on the epithelium.
