An enuresis electroconditioner pertains to the field of medical appliances and includes a humidity sensor (2) connected to an electric circuit which is activated in the presence of a liquid. When the liquid is detected, an electric current with a frequency of 50 Hz is generated. A qualified person must calibrate the amperage of the apparatus (1), adapting it to the sensibility of each person who, when receiving the electric impulse, contracts the perineal muscles, occluding the urethra and by a reflexive action inhibiting the contraction of the bladder and preventing urine loss.
