When using an indwelling urinary catheter, where should the drainage bag be positioned?

The drainage bag of an indwelling urinary catheter should be positioned below the level of the bladder. This positioning is essential for preventing backflow of urine, which can lead to infection and other complications. When the bag is kept lower than the bladder, gravity assists in the drainage of urine, ensuring it flows freely from the bladder into the bag without any obstruction. Additionally, keeping the drainage bag below the bladder reduces the risk of introducing pathogens back into the bladder, thus maintaining a sterile urinary tract and promoting patient safety and health.
