Abstract
A method for removing fluid from a patient is provided, the method including: deploying a ureteral stent or ureteral catheter into a ureter of a patient to maintain patency of fluid flow between a kidney and a bladder of the patient; deploying a bladder catheter into the bladder of the patient, wherein the bladder catheter comprises a distal end configured to be positioned in a patient's bladder, a drainage lumen portion having a proximal end, and a sidewall extending therebetween; and applying negative pressure to the proximal end of the bladder catheter to induce negative pressure in a portion of the urinary tract of the patient to remove fluid from the patient.
