Abstract: A bladder catheter comprising an elongate tubular body having a proximal portion with a proximal end, a distal portion, preferably between at least about 8 cm and 30 cm, with a distal end and a retaining portion with retaining mechanism disposed between the proximal portion and the distal portion. The tubular body of the bladder catheter further comprises a drainage lumen extending therethrough from a drainage port in the proximal end to at least one opening in the distal portion. The distal end of the catheter preferably comprises a weight. A method of continuously draining urine in a patient, comprising the steps of inserting a bladder catheter according to the present invention into the patient's urethra until the retaining mechanism and distal portion reside within the patient's bladder, actuating the retaining mechanism of the catheter, allowing the distal end of the catheter to fall into the dependent portion and, thereby, draining urine in the dependent portion of the bladder.
