Pelvic floor muscle training is the mainstream of the non-operative treatment for female stress urinary incontinence. However, in order to make this method effective, it is mandatory to learn how to correctly contract pelvic floor muscles. Thirty adult women suffering from mild stress incontinence were instructed to train their pelvic muscles using vaginal cones. They retained cones of increasing weight in the vagina by contracting pelvic floor for 15 minutes twice a day. Twenty-seven of 30 (90%) patients could complete the training in five weeks. Both incidence and degree of incontinence decreased significantly after the training. The subjective improvement rate (incontinence cured or decreased by 50%) was 70%. The cone weights which they could hold over one minute and the voluntary pelvic floor contractions measured with the perineometer increased significantly, which indicated strengthening of pelvic floor muscles. Vaginal cones have a shape similar to tampons and are accepted by Japanese women with little psychological resistance. This device helps the patients to understand how to contract pelvic floor muscles and to motivate them to continue training, thus contributing for the treatment of stress incontinence.
盆底肌训练是女性压力性尿失禁非手术治疗的主流方法。然而，为使该方法有效，必须学会如何正确收缩盆底肌。30名患有轻度压力性尿失禁的成年女性被指导使用阴道球囊训练盆底肌。她们通过每天两次收缩盆底肌15分钟，在阴道内留置重量逐渐增加的球囊。30名患者中有27名（90%）能在五周内完成训练。训练后，尿失禁的发生率和严重程度均显著降低。主观改善率（尿失禁治愈或减轻50%）为70%。她们能保持一分钟以上的球囊重量以及用会阴张力计测量的自主盆底肌收缩显著增加，这表明盆底肌得到了强化。阴道球囊形状类似于卫生棉条，日本女性对其接受度高，心理抵触小。该装置有助于患者了解如何收缩盆底肌，并激励她们持续训练，从而有助于压力性尿失禁的治疗。
