Purpose: The role in pregnancy prevention is controversial, and we aimed at identifying the factors that influence the success of preventive scratch in single pregnant women. Materials and Methods: The main measure of scratch failure is 32 weeks before premature birth in this study, the cases applied in a single center of proflactic cervical scratch were studied retrospectively. As an indication for preventive screening, criteria were sought for patients with either two or more late history of pregnancy or early history of pregnancy in the current pregnancy to be 25 mm short of cervical ultrasound in the current pregnancy. Factors forecasting success as age, body mass index, uterine intervention history, low history in the second trimester, passed conization, pre-serging positive vaginal culture, the week of pregnancy in which the serging was performed, a week after the serging C-reactive protein levels and transvaginal ultrasound tested changes in the cervical length two weeks after the serging. Identifying statistics and binary logistical regression analysis were made. Results: 152 women were subjected to cervical screening between 2011 and 2018. Clinical surveys were included in the study of patients with 54 single pregnancies, which were given regular, McDonald procedure preventive screening and thus meeting the study criteria. Multi-variable analyses in our study showed that the pre-gravity for the failure of the serclature [OR=2,124 (1,846-4,111) p=0,016], the pre-gravity after the 20th week of pregnancy [OR=1,126 (1,020-1,232) p=0,04] and the history of uterus instrumentation [OR=1,342 (1,214, 7,873) p=0,015] are independent predictive factors. 33 (61%) of the patients who were given proflactic scraps gave birth after 32 weeks. The result: This study showed that uterine interventions, the presence of scratch history and the application after 20 weeks of pregnancy were independent risk factors in the success of profylactic scratch. There are significant clinical outcomes for women in the fertility age, especially when taking into account the low/low management of uterine instrumentation. Therefore, women considering surgical discharge should be informed about potential risks and medical management or cervical maturity should be considered.
