TRANSVAGINAL ULTRASONOGRAPHIC MEASUREMENTS OF ENDOMETRIAL THICKNESS -A REPRODUCIBILITY STUDY

Objective: The study was undertaken to assess the reproducibility of e ndometrial thickness measurements by transvaginal ultrasonography (TVS ). Methods: In a prospective blind study, two examiners measured the e ndometrial thickness of 25 patients by TVS on two separate occasions 3 0 minutes apart. Results: The reliability test performed for each exam iner was statistically less significant for the intra-observer variati on of each observer (r = 0.95 and r = 0.93), than between both examine rs (r = 0.85). Although there was no statistically significant differe nce 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. (C) 1996 John Wiley & Sons, Inc.
