It is very important to take good care of the suprapubic tube and drainage system. They should be kept very clean. The bag should not be allowed to drag on the floor.
If the bag is accidentally cut or begins to leak, it must be changed to prevent germs that may cause infection from entering the system. An opening anywhere along the entire system of tubing and bag will allow bacteria to enter. If these would then reach your child's bladder, a urinary tract infection could result. It is not acceptable to place the drainage bag in a plastic bag if it leaks.
