This Tru-Close Nephrostomy Drainage Bag is used to collect urine from a surgically placed drain tube in a kidney. Its stretchable, 20-inch, inlet tubing can be cut to a desired length, and it also features an easy, twist-open and close drain value and leg straps. Plus, this graduated collection bag allows users to see exactly how much urine has been collected, and it is soft and pliable for patient comfort.
