寄生虫直接侵犯泌尿系统虽较少见,但侵袭泌尿系统邻近的血液、淋巴循环或由于全身性感染、免疫损伤等而引起泌尿系统病变并不少见。寄生虫成虫或虫卵可侵犯尿道、膀胱、输尿管或肾脏等部位,造成局部炎症性病变或功能性损害,而引起临床症状。由于寄生虫致病性和发病机制的不同,泌尿系不同部位病变和病理生理改变的差异,因此临床表现较为复杂,不同寄生虫可引起相似的临床症状,而同一种寄生虫又可引起多种不同的临床表现。略述较常见的寄生虫性泌尿系病变。滴虫性尿道炎阴道毛滴虫主要寄生于女性的阴道及尿道等,以及男性的尿道、前列腺等泌尿生殖器官。阴道毛滴虫滋养体在外界环境中有很强的抵抗力,可通过性生活直接传播或坐式厕所、公共浴室、浴
It is not uncommon for parasites to directly invade the urinary system. However, it is not uncommon for urinary system lesions to invade the blood, lymphatic circulation adjacent to the urinary system, or due to systemic infections, immune damage, and the like. Parasite adults or eggs can invade the urethra, bladder, ureter or kidney and other parts, causing local inflammatory lesions or functional damage, causing clinical symptoms. Because of the different pathogenicity and pathogenesis of the parasite, the difference of pathological and physiological changes in different parts of the urinary tract, so the clinical manifestations are more complex, different parasites can cause similar clinical symptoms, and the same parasite can cause a variety of Different clinical manifestations. A brief overview of the more common parasitic urologic lesions. Trichomonas urethritis Trichomonas vaginalis parasitic mainly in women’s vagina and urethra, as well as men’s urethra, prostate and other genitourinary. Trichomonas vaginalis trophozoites in the external environment has a strong resistance, can be transmitted directly through sexual life or sitting toilet, public bath, bath
