Abstract

  A previous study reported the effectiveness of supportive underwear for elevating the bladder neck and reducing symptoms of stress urinary incontinence in women. This study investigated the mechanism by which bladder neck elevation occurs by using supportive underwear. The positions of the bladder neck and anatomical structures of the pelvis with and without underwear of different forms, strengths, and supportive regions were compared in 10 parous women using magnetic resonance imaging. The underwear that supported from the femur to the buttock, with high strength, or that supported from the pubis to the coccyx was effective to elevate the position of the bladder neck. The levator plate was lifted forwards and upwards by the underwear in elevating the bladder neck. In addition, the perineal body was also lifted upwards. The support to the perineal body and the support from the pubis to the coccyx might be effective to elevate the bladder neck.
