RESUMEN
The authors demonstrate technique for obtaining endometrial fragments in 25 patients sent to Gynecological Cancer Preventive Service of the Arnaldo Vieira de Carvalho Cancer Institute, during the period of September 1991 through January 1992, presenting abnormal uterine hemorrhage. Technique consists in vacuum aspiration with the support of a No. 12 uretral sonde, provided with one lateral opening only. Correlation with curettage was positive in 88% of the patients; biopsy with sonde did not result in confirmation in three patients only. No complications at all were observed (infection, hemorrhage or uterus perforation). Authors understand that this method is in conformity with a correct diagnostic performance, being a low cost procedure, almost painless, easy to be done and furnishing sufficient material for the histo-pathologic diagnosis, in 88% of the cases studied.
