Clarity RMS™ is a critical care monitoring system that continuously measures urine flow, automatically transmitting to the medical staff real-time data, and notifications of fluctuations, on a 24/7 basis. This information, which reflects changes in renal function, provides an early sign of AKI risk and facilitates rapid intervention. In addition, it is invaluable for monitoring treatment efficacy and managing fluid balance.
The Clarity RMS Electronic Sensor
easily connects to a Foley catheter, where it continuously and reliably measures critical fluctuations in urine flow. In addition, real time core body temperature can be measured, when used with a temperature-sensing Foley catheter.
*Single patient use
The Clarity RMS Console –
Embedded technology in this battery-powered bedside monitor continuously calculates and transmits real-time data from the sensor directly to all hospital information systems.
The Clarity RMS Intelligent Notification System
notifies the medical team as soon as the patient’s urine flow rate is below the threshold set by the user for urine output (ml/kg/hour), based on the RIFLE, AKIN, and KDIGO criteria.

Our Technology
The Clarity RMS™ critical care monitoring system utilizes a sophisticated method for measuring a non-homogeneous, time-varying liquid in an unstable, uncontrolled environment. This method is based on a combination of company know-how as well as patented sensor technology and proprietary algorithms.
RenalSense’s approach involves complex numeric techniques based on an in-depth understanding of fluid dynamics, thermodynamics, human physiology and the properties of the target environment. This knowledge is based on the compilation and analysis of tens of thousands of hours of clinical data in multiple, varied environments over seven years. In addition, 3D numerical simulators and machine learning technology were used for analysis of human urine and interpretation of its flow waveform.
Our patented sensor technology measures, analyzes and interprets the continuously changing composition and flow volume of urine, generating a unique set of electronic signals.
Proprietary algorithms separate the “noise” from these signals with high sensitivity and stability, achieving clear recognition and correct interpretation of different processes in an extremely dynamic environment.
Standard flow sensors cannot possibly cope with this degree of variability, as they require calibration to specific ranges of volume and composition.
Our patented sensor technology has been miniaturized and optimized for:
- Small footprint – of both the sensor and the bed-mounted console
- Low power – battery operated, lasts for days
- Low cost – disposable, 1 per patient
The Clarity RMS critical care monitoring system also uses sophisticated encryption technology based on military-grade ECC public-key cryptography for accurate data transfer between the console and sensor kit.
Clinical Data
A prospective study conducted in Israel with 95 ICU patients demonstrated that continuous electronic monitoring of urine output with the Clarity RMS identified significantly more cases of AKI according to the KDIGO criteria than serum creatinine (SCr) alone. Additionally, in patients that fulfilled AKI definitions using both the SCr and UO criteria, electronic UO measurements identified AKI significantly earlier than SCr.

A prospective study conducted at the University of Pittsburgh Medical Center (UPMC) with 44 cardiothoracic surgery intensive care unit (ICU) patients demonstrated that electronic monitoring of UO with the Clarity RMS was significantly more accurate than manual measurements recorded by the nursing staff. In addition, hourly measurements with the Clarity RMS were significantly more reliable than manual measurements, with only 8.6% missed, as opposed to 39% missed by the nursing staff. The difficulty in obtaining timely and accurate manual measurements of UO can result in delays in detecting oliguria and potentially lead to missed cases of AKI.
