PROBLEM TO BE SOLVED: To provide a determination method for urination disorder.SOLUTION: (1) A determination method for urination disorder is capable of quantitatively measuring a tendency of a micturition desire in a urine collection period by staging the bladder perception by using bladder capacity measurement and a VAS. (2) When a value obtained by subtracting a VAS value at a start of a urine collection period from a VAS value at an end of the urine collection period is divided by a value obtained by subtracting a bladder capacity at the start of the urine collection period from a bladder capacity at the end of the urine collection period, the obtained inclination value shows a value specific to the urination disorder.
