[Cervix incompetence].
The incontinence cervix is one of the most controversial topics in obstetrics and gynecology. The cause of cervical incontinence is due to trauma to the cervix resulting from injury during childbirth, mechanical dilation, or surgery. Dilatation of the internal cervical os is difficult to detect by digital examination in patients with a closed external cervical os. Transvaginal ultrasonographic assessment of the cervix should be adopted as the "gold standard".
