Abstract: Described herein are devices and methods for continuous real time monitoring of kidney function. In various embodiments, a urine analysis device collects sensor data describing one or more properties of urine. The urine analysis device may be integrated with a catheter system to continuously generate sensor data in real time as the urine is collected by the catheter system. Sensor data collected by the urine analysis device may be analyzed by physicians to detect changes in a patients kidney function. If necessary, based on the sensor data, physicians may perform an intervention to improve a patients kidney function.
