==== Causes ==== | ==== Causes (5) ==== | ||
#'''Bladder dysfunction''' | |||
#*Can be of a congenital, acquired, or behavioral nature | |||
#*Often the cause of secondary VUR | |||
# '''Posterior urethral valve''' | |||
#* '''Most common cause of bladder outlet obstruction in infants''' | |||
#** '''In females, anatomic bladder obstruction is rare. The most common structural obstruction in females is from a ureterocele that prolapses into the bladder neck.''' | |||
#* Reflux is present in 48-70% of patients with PUV patients | |||
# '''Neurogenic bladder''' | |||
#* '''Spina bifida, in particular, is at risk for VUR''' | |||
#** '''Special attention for the potential for occult spinal dysraphism is warranted during evaluation of any child with UTI''' | |||
#* '''Urodynamic risk factors for VUR:''' | |||
#*# '''Overactivity''' | |||
#*#* '''Most common urodynamic abnormality associated with VUR in neurologically normal children''' | |||
#*#* Overactive bladder frequently can be responsible for reflux | |||
#*# '''Inadequate or obstructive voiding patterns''' | |||
#*# '''Higher voiding pressures (may be due to inadequate sphincter relaxation)''' | |||
# '''Urinary Tract Infection''' | |||
#* UTIs and their accompanying inflammation can also cause reflux by: | |||
#*# Lessening compliance | |||
#*# Elevating intravesical pressures | |||
#*# Distorting and weakening the ureterovesical junction | |||
# '''Bladder and bowel dysfunction (BBD)''' | |||
#* In older children, acquired abnormalities in bladder and bowel function commonly known as bladder and bowel dysfunction (BBD'')'' have been associated with reflux | |||
