Catheters may be inserted as an in-and-out procedure for immediate drainage, left in with a self-retaining device for short-term drainage (as during surgery), or left indwelling for long-term drainage in patients with chronic urinary retention.
An indwelling Foley catheter remains in place continuously as shown in the video. It keeps the catheter from slipping out by having a balloon on one end that is inflated with sterile water after that end is inside the bladder.
