A urine detection method and a urine detection device are disclosed. Based on types of components to be detected in urine, an equal number of urine samples of a preset volume as the types of components to be detected are selected, wherein each urine sample is used for detecting one component; for each urine sample, based on a component to be detected, the urine sample is mixed with a preset detection object of a fixed mass that can react with the component to be detected in the urine; one or more micro current values of a mixture of the urine sample and the preset detection object within a preset time period are detected; a micro current average value based on the one or more micro current values within the preset time period is calculated; the micro current average value is compared with a pre-established corresponding relationship table of contents of a preset component content and the micro current average values, so as to determine content of the component to be detected in the urine, wherein the preset component is same as the component to be detected.
