An improved urinary catheter device having a urine collection bag selectively drains the bladder or provides a fluid pathway to the bladder for injecting an amount of medication therein. A multi-position valve can be manipulated from a position in which fluid is allowed to drain into the catheter bag to a position in which a fluid delivery pathway is provided to the bladder. In one embodiment a fluid delivery device is connected to the fluid delivery pathway provided. The fluid delivery device can be pressurized so that manipulation of the multi-position valve results in the fluid contents of the fluid delivery device being forced into the patient's bladder. A method for using the device drains the bladder of a patient into the catheter bag, and manipulates the valve to inject an amount of medication into the patient's bladder without opening or piecing the catheter bag.
