An apparatus, system and method of monitoring urine output. The apparatus, system and method includes at least one exit route for the urine output, a collection point for the urine output, and at least one output reader for display of at least one output reading. The output reader includes a detector, such as a weight sensor, an ultraviolet sensor, a float sensor, a mechanical diaphragm/counter, or an electromechanical or electrical sensor, through which the urine output passes, at least one local memory at which a counter output of the detector is stored, and a buffer that forwards the counter output accumulated at the at least one local memory to at least one remote memory at a predetermined interval.
