Endometrium biopsies are currently carried out with the Novak curette. The drawbacks of this procedure are well known. The use of a female, disposable, sterile, plastic urinary catheter is a useful, easy, painless, dangerless and repeatable alternative to obtain suitable endometrium samples for histopathologic diagnosis. Since a small endometrial cancer can be overlooked, selection of patients is obligate, but this holds also insofar as all methods of endometrium biopsy are concerned. Accordingly, the procedure is primarily suitable in cases of "dysfunctional" bleeding.
