非特异性尿路感染的女性发病率10倍于男性,女性所以易感,其原因如下: 1.女性尿道直而宽短,不是一个良好的屏障,易受肛门、会阴部细菌的侵袭,进入尿道、膀胱,引起上行性感染。据Taylor及Morgan论证,男性的精液及前列腺液中含有抗菌因子,在抗病菌侵袭上有一定作用,不易发生尿路感染,而女性则缺乏抑制细菌的物质。 The incidence of non-specific urinary tract infection in women 10 times higher than men, so women are susceptible to the following reasons: 1. Female urethra straight and short, not a good barrier, susceptible to anus, perineal bacteria invasion, into the urethra Bladder, causing an upward infection. According to Taylor and Morgan’s demonstration, men’s semen and prostatic fluid contain antimicrobial agents, which have a role in anti-bacterial invasion and are less likely to develop urinary tract infections, while women lack bacterial-inhibiting substances.
