A medical procedure kit includes a single-layer tray (100) having a first compartment (101) at least partially bounded by a first base member (107) and a second compartment (102) at least partially bounded by a second base member (108). At least one syringe (901) is situated within the first compartment. A Foley catheter (701), coupled to coiled tubing (702) and a fluid drain bag (703), is disposed within the second compartment. This catheter assembly is inverted, with the Foley catheter (701) and the coiled tubing (702) positioned between the second base member (108) and the fluid drain bag (703).
