Transvaginal ultrasonographic measurements of endometrial thickness: a reproducibility study.

Author information

Department of Obstetrics and Gynecology 1B, Tel Aviv Medical Center, Serlin Maternity Hospital, Israel.



The study was undertaken to assess the reproducibility of endometrial thickness measurements by transvaginal ultrasonography (TVS).


In a prospective blind study, two examiners measured the endometrial thickness of 25 patients by TVS on two separate occasions 30 minutes apart.


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.


A safety margin of error should be taken into consideration while recommending a cutoff under which no curettage is needed.
