A bladder catheter is provided. The bladder catheter includes: a proximal portion configured to be positioned in at least a portion of a patient's urethra； and a distal portion configured to be positioned in a patient's bladder, the distal portion including a retention portion, wherein the retention portion includes an inwardly facing side including one or more perforations and an outwardly facing side, and wherein, when negative pressure is applied through the bladder catheter, fluid is drawn into the bladder catheter through the one or more perforations while bladder walls are prevented from appreciably occluding the one or more perforations by contact with the outwardly facing side of the retention portion.
