The invention relates to a urinary incontinence treatment apparatus which comprises a patient loading part (4) and an ultrasonic transmitter (5). The patient loading part (4) is used for loading a patient for treatment, the ultrasonic transmitter (5) is arranged on the patient loading part (4), the buttock of the patient is seated on the ultrasonic transmitter (5) when the patient is located on the patient loading part (4), and ultrasonic wave transmitted by the ultrasonic transmitter (5) acts on pelvic floor muscles of the patient. Thermogenetic effect, cavitation effect and mechanical effect of ultrasound are mainly utilized to stimulate the pelvic floor muscles of the patient, so that changes that are beneficial to restoring the pelvic floor muscles are generated in tissue of the pelvic floor muscles, and the effect of improving urinary incontinence is achieved.
