Uterus didelphys is a rare congenital anomaly of the female reproductive tract characterized by a divided uterine cervix and body. It occurs due to abnormal development of the paramesonephric (Müllerian) duct. Different forms of uterus didelphys have been reported in several animal species, including bovine, equine, ewe, goat, swine, and bitch. However, there is no previous report that has documented a completely divided female genital tract in she-camel. Moreover, there is a lack of literature regarding this anomaly in animals. Therefore, the present study reports, for the first time, a rare case of a completely divided female genital tract in a she-camel. In addition, the existing relevant literature on uterus didelphys in different animal species is reviewed.
A female reproductive tract of she-camel, approximately 10 years old, with a history of previous successful pregnancy, was brought to the anatomy department following the slaughtering of the animal. Initial examination revealed a normal reproductive tract consisting of two ovaries, two fallopian tubes, a uterus, and a vagina. A closer examination revealed a completely divided vagina, with an external os opened into each part of the vagina, as well as a divided uterine body and cervix. Intrauterine infusion of saline through one external os confirmed complete separation of uterine body and cervix.
To the authors' knowledge, this is the first reported case of a completely divided female genital tract in a she-camel. This review summarizes the previous reports about uterus didelphys in farm animals.
双子宫是一种罕见的女性生殖道先天性异常,其特征为子宫颈和子宫体分隔。它是由于副中肾管(苗勒管)发育异常所致。在包括牛、马、母羊、山羊、猪和母犬在内的几种动物物种中,已报道了不同形式的双子宫。然而,此前尚无关于单峰驼母驼女性生殖道完全分隔的报道。此外,关于动物中这种异常情况的文献也很缺乏。因此,本研究首次报道了一例单峰驼母驼女性生殖道完全分隔的罕见病例。此外,还对不同动物物种中双子宫的现有相关文献进行了综述。
一头约10岁、有过成功妊娠史的单峰驼母驼的女性生殖道,在该动物被屠宰后被送至解剖学系。初步检查发现生殖道正常,包括两个卵巢、两条输卵管、一个子宫和一个阴道。进一步检查发现阴道完全分隔,每个阴道部分都有外口,子宫体和子宫颈也分隔开。通过一个外口向子宫内注入生理盐水证实了子宫体和子宫颈完全分离。
据作者所知,这是首次报道的单峰驼母驼女性生殖道完全分隔的病例。本综述总结了此前关于家畜双子宫的报道。
