Purpose
This retrospective cross-sectional study evaluated the correlation among pelvic organs’ size, correlation of sizes with age, the change of uterine and cervical sizes in presence and absence of pathologies, and the pattern of ovarian volume asymmetry in the absence of pathology.
Patients and methods
Measurement of pelvic organs from all consecutive premenopausal, non-pregnant patients who underwent TVS for gynecologic workup were included in the analysis. The correlation of the sizes, and variation of sizes among a finding-based category was checked.
Results
Data from 43 women with mean (±SD) age of 33.4±8.7 years were included. Among the finding-based categories, bulky uteri in comparison to normal uteri were more likely to harbor myoma or adenomyosis (Risk ratio 2.07, p < 0.01). Positive correlations were found between, antero-posterior (AP) diameter of uterus and age (R 0.4, p < 0.01), AP diameter of uterus and its length (R 0.7, p < 0.01), AP diameter of uterus and cervix (R 0.44, p < 0.01), length of uterus and that of cervix (R 0.37, p < 0.05), AP diameter of cervix and it length (R 0.47, p < 0.01) and pair of otherwise healthy ovaries (R 0.53, p < 0.01). This dataset suggests that the presence of pathologies may not always be associated with uterine enlargement (p > 0.05), but the presence of a pathology is associated with enlargement of uterine cervical AP diameter (p < 0.01) as well as its length (p < 0.05). Among the healthy pairs of ovaries, the right one was larger than the left with a significant difference between the mean volumes (p < 0.05), in 70.4% pairs.
Conclusions
Overall, the findings from this small series are expected to add factual evidence to our existing concepts and help to shape some future research questions.
