Abstract
A method for removing excess fluid from a patient with hemodilution is provided. The method includes: deploying a urinary tract catheter into the patient such that flow of urine from the ureter and/or kidney is transported within a drainage lumen of the catheter; applying negative pressure to the ureter and/or kidney through the drainage lumen of the catheter to extract urine from the patient; periodically measuring a hematocrit value of the patient; and if the measured hematocrit value is greater than a predetermined threshold value, ceasing the application of the negative pressure to the ureter and/or kidney. A system for removing excess fluid from a patient with hemodilution including a ureteral catheter and a pump is also provided.
