A drainage catheter system including a catheter, a collection bag, and a collection bag saddle, is provided. The catheter includes a catheter body having an interior lumen, an elongate tubular sheath operatively associated with the catheter body, and a layer of lubricant disposed between the catheter body and the tubular sheath. The sheath is inflatable after deployment to provide sealing engagement with an inner wall of the urethra. One end of the catheter body is adapted to be connected to the collection bag which includes a fluid entry portion having a one-way fluid valve, a gas separation chamber, and a one-way gas valve. The collection bag also includes a main liquid reservoir in fluid communication with the fluid entry portion and a sealed drainage member for permitting drainage of the main liquid reservoir. The collection bag saddle facilitates attachment of the collection bag to a patient's body, and includes a main body portion, a plurality of mounting pads attached thereto including adhesive backings, and collection bag mounting structure formed in the main body portion.
