Transvaginal ultrasonographic measurements of endometrial thickness: A reproducibility study

Abstract

Objective The study was undertaken to assess the reproducibility of endometrial thickness measurements by transvaginal ultrasonography (TVS). Methods In a prospective blind study, two examiners measured the endometrial thickness of 25 patients by TVS on two separate occasions 30 minutes apart. Results The reliability test performed for each examiner was statistically less significant for the intra‐observer variation of each observer (r = 0.95 and r = 0.93), than between both examiners (r = 0.85). Although there was no statistically significant difference between the observations, the mean range of observations was 2.12 + 1.27 mm. Conclusions A safety margin of error should be taken into consideration while recommending a cutoff under which no curettage is needed. © 1996 John Wiley & Sons, Inc.

Measurement precision and normal range of endometrial thickness in a postmenopausal population by transvaginal ultrasound

“…In order to analyze the differences between the observers, we have tried to minimize these variables by using only two different machines and the same measurement techniques, and by only examining women more than 5 YSM, since their endometrium varied the least in the cross-sectional study. This is the first time that the variation of the postmenopausal endometrium has been examined over time, and it probably reflects 'real life' more reliably than do earlier reproducibility studies 18,19,[22][23][24] , in which measurements were performed on the same day or by reviewing recordings of the examinations. Due to more potential confounding factors in our long-term study, a lower reproducibility than previously reported could be expected.…”

Reproducibility of Endometrial Vascular Patterns in Endometrial Disease as Assessed by Transvaginal Power Doppler Sonography in Women With Postmenopausal Bleeding

“…1 This method has been shown to be very reproducible among different examiners, even in examiners with little experience. [13][14][15][16] However, this technique is nonspecific for discriminating among different endometrial diseases. Transvaginal color and power Doppler sonography was introduced in an attempt to refine the diagnosis of endometrial disease when ultrasound is used.…”

Histopathological Study of Endometrium in Postmenopausal Bleeding

“…It requires immediate investigations for early diagnosis, follow up and prompt treatment. The primary assessment in all cases of PMB should be by transvaginal ultrasound scanning (TVS) as the thickening of endometrium may indicate significant pathology 6 A woman not taking hormone replacement therapy (HRT) who bleeds after the menopause has a 10% risk of having genital cancer and a further 10% risk of significant pathology 2 . About 90% of patients with endometrial carcinoma have vaginal bleeding or discharge as presenting symptoms.…”
