A urine collection bag having the basic features appearing in U.S. Pat. No. 4,449,971 is disclosed. The bag also includes an improvement in the form of an extendable drain tube that is normally retracted and retained in flat coiled condition against the front wall of the bag. The tube is biased into its coiled condition by the elastic memory of the thermoplastic material from which it is formed and, in a preferred embodiment, the flat coil is oval-shaped with its major axis extending generally vertically when the bag is worn. A retention strap attached to the front wall of the bag serves to hold the drain tube in its coiled condition against the bag's front wall. A valve is located at a distal end of the drain tube, which is used to control drainage. The location of the valve prevents spillage of residual urine upon recoil of the drain tube.
