Bladder ultrasound increases catheterization success in pediatric patients

  • Next time before you attemt to catheterize a child under 36 months measure the transverse bladder diameter with the ultrasound first. 
  • If it is > 2 cm you are much more likely to be successful in obtaining the specimen on the first attempt. 
  • 94% when ultrasound measurement was used versus 68% patients who had conventional catheterization.
