Draining the bladder into a bag outside the body uses an indwelling urinary catheter which is a long tube with a balloon that is inflated after being inserted in males. The tube that drains the urine must not be tugged or become kinked. In males, tape or a special fastening device attach the tube to the client’s inner thigh. Never attach the tube to anything except the client’s inner thigh. The drainage bag should remain lower than the client’s bladder to prevent back-flow of urine.
