A suprapubic (SP) catheter is a tube that drains urine (pee) from the bladder. A surgeon inserts the tube through a small hole (stoma) in the belly and it goes directly into the bladder. The catheter carries urine from the bladder to a drainage bag.
Your care team may teach you how to change your child’s SP catheter. If so, change the catheter every 4–6 weeks, or as often as your child’s doctor tells you.
