Comparison of Cervical Length Using Pelvic Organ Prolapse Quantization System and Transvaginal Sonography
Abstract
According to previous studies, there is a direct relationship between pelvic limb prolapse (POP) and cervical elongation. The aim of this study was to compare the length of the cervix based on the quantitative system of pelvic limb prolapse (POP-Q) as an indicator test with ultrasound in patients with POP. We assume that measuring cervical length using POP-Q, CE is forgotten in some patients, and transvaginal cervical imaging is a reliable and repeatable method for assessing cervical length.
Methods: In this cross-sectional study, after confirmation of ethics, 100 women with pelvic limb prolapse were included in the study. Initially, POP staging was performed based on the POP-Q system, and cervical length was determined by a gynecologist based on C-D measurements. Then all women underwent transvaginal ultrasound and cervical length were compared in two ways. SPSS / Ver24 was used for statistical analysis.
Results: In this study, the age of patients was 47.88. 8.7 years and the mean BMI was 26.19. 1.53 weight per square meter. The total length of the vagina (TVL) was 9.00 ± 1.20 cm (minimum 7 cm and maximum 11 cm). The results of measuring cervical length by POP-Q method showed that it was 11.22 80 80.40 (SD) mm. Ultrasound results showed that this ability was 36.8 6 6.86 mm. Intra-class correlation (ICC) multiplication was used to evaluate the agreement between the two measurements and the results showed that the intra-class correlation is 0.476 (CI95%: 0.220-0.648). Given the value obtained for the ICC, there is a relatively weak agreement between the two indicators to measure cervical length. For this purpose, the Long-Altman method was used and the results showed that the rate of bias (mean difference) and standard deviation was 4.00 (19.20) with 95 agreement between -33.63 to 41.63.
