The invention relates to a method for ultrasonically extracting Volatile Organic Compounds (VOCs) in bladder. The method is characterized by comprising the following steps of asking a subject to suppress urine during the extraction of VOCs in the bladder, and starting extraction after filling of the bladder. A conventional medical B ultrasonic instrument is used as an ultrasonic source, a B ultrasonic probe moves back and forth in a zigzag mode on a surface of the outer skin of the bladder until the whole bladder is covered, ultrasonic waves reach the inner surface of bladder tissues through urine, and the bladder is promoted to release VOCs into the urine through vibration. The subject urinates to obtain a sample, and the VOCs in the urine sample are detected by using mass spectrometry. The method is simple and easy to operate, non-invasive, and capable of obtaining more VOCs with higher concentration in urine. 本发明涉及一种超声提取膀胱内挥发性有机物(VOCs)的方法，其特征在于：膀胱内VOCs提取过程中，要求受试者憋尿，膀胱充盈后开始提取。利用常规医用B超仪器作为超声波源，将B超探头在膀胱外皮肤表面来
