Correlation Between Hypertrophic Cervical Elongation and Pelvic Organ Prolapse.

OBJECTIVES

The association between hypertrophic cervical elongation and pelvic organ prolapse (POP) has been observed, but causation has not been determined. This study assessed the relationship of POP with hypertrophic cervical elongation according to menopausal status and the pelvic compartment involved in prolapse.

METHODS

This retrospective single-center case-control study was conducted at Shengjing Hospital of China Medical University between January 2017 and May 2019. Transverse and anteroposterior diameter of the cervix and cervical length were obtained by manual intravaginal measurement for 508 patients with POP and 510 patients without POP. Data were analyzed based on POP compartment and menopausal status.

RESULTS

In the premenopausal group, there was a statistically significant difference in the proportion of patients with hypertrophic cervical elongation in the non-POP and POP groups (P < 0.05); However, among postmenopausal patients, there was no statistical significance between these groups (P > 0.05). Patients with apical compartment POP had a higher proportion of occurrence of hypertrophic cervical elongation than those with nonapical compartment POP (P < 0.05).

CONCLUSIONS

Hypertrophic cervical elongation in premenopausal patients is significantly associated with POP; in particular, there is a significant correlation between apical compartment POP and hypertrophic cervical elongation.
