    Abstract: A continuous Glomerular Filtration Rate (GFR) estimation system may include a Foley catheter, a continuous urine creatinine sensor, and a urine output monitor. The continuous GFR estimation system computes creatinine clearance as CrCl = (U cr x U vol )/(P cr X I mim ), where U cr is urine creatinine in mg/dL, U Vol is urine volume in mL, P cr is plasma (serum) creatinine in mL, and I min is time in minutes. A Foley catheter may be used to withdraw urine from the bladder. The urine may be delivered to a urine output monitoi that provides the U vol value over a time I min . Attached to the catheter is the flow-thiough continuous urine creatinine sensor for providing the U cr value.The remaining parameter is P cr .Because serum creatinine levels do not change rapidly over time, a blood sample may be withdrawn prior to the start of the continuous GFR to obtain the P C r value.

    Abstract: A method for measuring urine flow out of a patient, urine from the patient being taken out from a urinary tract catheter arrangement and a tubing (1) connected to said arrangement, comprising arranging a sensor (3) in said tubing to determine urine flow in said tubing. The method is especially characterized by the step of- reducing the delay time for detecting urine flow transients by reducing the urine volume between the sensor (3) and the patient by locating the sensor close to the catheter arrangement outlet. The invention further relates to a further method, an arrangement, a device and a sensor for urine flow measurement.

    Abstract: A method for providing an image of an internal region of a patient has been developed. The method reduces imaging artifacts by providing enhanced contrast between tissue and blood during imaging. The method comprises administering to a patient a contrast agent in combination with a renal vasodilator and performing ultrasound imaging of the region. Renal disease, including renal arterial stenosis, may be diagnosed using the method.

    Abstract: A method and apparatus in which body fluid chemistry is measured in either differential or non-differential mode using apparatus of the kind employed in infusing fluids into patients' blood streams, either with or without combination with such infusion, to the end that measurement of body fluid chemistry is conveniently and measured automatically at selected frequency. The infusant is contained in a bag (14) which hangs from arm (16) of the pole. The infusant flows by a flowpath, in this case conduit (18), to a flow pump and controller (20). Thereafter, it flows by a continuation of the flowpath in tube (22) past an analyzer instrument (24) to an electrode bloc (26). The bloc (26) is strapped to the patient's wrist. A tube (28) conducts fluid from block (26) to an intravenous needle (30).
