Sexually related recurrent urinary tract infections were caused by a method of contraception, the diaphragm, in 74 per cent of the women in this study. Urodynamic studies demonstrated severe alteration in urinary flow and elevation of the bladder neck angles. By altering the fit of the diaphragm, or changing to another form of birth control, 96 per cent of these women were infection-free at one year without antibiotic suppression.
在本研究中，74%的女性与性相关的复发性尿路感染是由一种避孕方法——子宫托引起的。尿动力学研究表明尿流严重改变，膀胱颈角度升高。通过调整子宫托的贴合度或改用另一种避孕方式，这些女性中有96%在一年内无需抗生素抑制即可无感染。
