title: Assessment with transvaginal ultrasonography of endometrial thickness in women with postmenopausal bleeding.
abstract: OBJECTIVE
  The aim of this study was to assess the use of transvaginal ultrasonography in measuring endometrial thickness in postmenopausal women with bleeding, thus to determine the least invasive treatment.
  
  
  METHODS
  We evaluated 168 women with postmenopausal bleeding by transvaginal ultrasonography and histological study of the endometrium.
  
  
  RESULTS
  No cancerous or precancerous lesions were found when endometrial thickness was under 10 mm. The mean endometrial thickness in women with cancerous and precancerous lesions was 10.75 +/- 1.63 mm, while in non-pathological lesions it was 1.36 +/- 1.18 mm.
  
  
  CONCLUSIONS
  To diagnose endometrial pathology, an endometrial thickness over 6 mm yields a sensitivity of 88.6%, a specificity of 90.6%, a positive predictive value of 92%, with 4.6% of false-positives and 4.6% of false-negatives (six small polyps and one irregular maturation). Although we are waiting for other prospective and multicentric studies, our present experience leads us to believe that Dilatation and Curettage (D&C) can be avoided in postmenopausal bleeding with endometrial thickness under or equal to 6 mm.
