1. A uroflowmeter comprising:
a sensor having a signal transmitter transmitting an input signal to a detection area and a signal receiver receiving an echo signal reflected from urine passing through the detection area;
a signal processing unit calculating uroflowmetry data based on a difference between the input signal and the echo signal, the uroflowmetry data being data about a flow of the urine passing through the detection area; and
a diagnosis unit diagnosing urinary disorders of a test subject by comparing the uroflowmetry data calculated by the signal processing unit with preset reference uroflowmetry data,
wherein the uroflowmetry data comprises a urinary flow rate at a distal end of a test subject's genitalia,
wherein the sensor comprises:
a first sensor having a first signal transmitter transmitting a first input signal in a first direction toward the detection area and a first signal receiver receiving a first echo signal reflected from the urine passing through the detection area; and
a second sensor having a second signal transmitter transmitting a second input signal in a second direction crossing the first direction toward the detection area and a second signal receiver receiving a second echo signal reflected from the urine passing through the detection area,
wherein the signal processing unit calculates a velocity of a falling urine stream discharged from the test subject by vector summation of a first urinary flow rate obtained from the first sensor and a second urinary flow rate obtained from the second sensor, the first urinary flow rate being a flow rate of the urine passing through the detection area with respect to the first direction, the second urinary flow rate being a flow rate of the urine passing through the detection area with respect to the second direction.
