Oblique vaginal septum

Vaginal oblique septum is a not very rare genital malformation. Strange clinical manifestations often cause delays in diagnosis and treatment. And in general textbooks there are no or few introductions. The definition of the vaginal oblique septum mainly includes the following aspects: 1. Double uterus and double cervix, some may have a single cervix with uterine mediastinum. 2. The vaginal oblique septum is different from the vaginal mediastinum which divides the vagina into two sides, and the vaginal septum which divides the vagina into two sections. The oblique vaginal septum appears as a piece of membranous tissue that covers the vaginal epithelium on both sides. It originates between the two cervix and obliquely rises to the vaginal wall on one side, forming a blind tube to shield the cervical on that side. There is a cavity between the back and the cervix as the posterior septal cavity. 3. Urinary malformations, almost without exception, are combined with the absence of kidneys and ureters on the same side as the oblique septum. This case was first reported in the literature in 1992, but there was no suitable designation, and some were named uterus didelphys with unilateral imperforate vagina. Because this abnormality is manifested by a vaginal oblique septum, it is most appropriate to call it vaginal oblique septum syndrome.
