Abstract: A urethral catheter device and an associated method of using the device are disclosed. The device comprises a catheter probe and at least one receiving unit attachable to the probe for receiving and collecting urine. The catheter probe comprises: an elongated shaft, a valve, a drainage lumen, a drainage inlet, a tapered cone, a collar, an elongated protuberance, a saline inlet, a saline lumen, a sheath, and a fluid lock. Each receiving unit comprises: a sterile membrane, a sleeve, and a collection bag. When the sleeve of the receiving unit is attached to the collar of the catheter probe, then the tapered cone of the catheter probe ruptures the membrane of the receiving unit, whereby the drainage inlet of the proximate end of the catheter probe is fluidly connected to the collection bag of the catheter probe and the valve is thereby opened. The sheath attached at the proximate end of the elongated shaft is inflatable into a donut shaped balloon which is capable of being retained within a bladder of a patient.
