A five-year experience with intrauterine washing cytology.

The results of a five-year experience using a Gravlee-type device for endometrial cytologic sampling in 1,215 patients are presented. Cytohistologic correlation in 620 cases confirmed the difficulty of using cytology to diagnose normal endometrium and its benign changes. Our use of intrauterine washing cytology indicated 66 malignancies, 59 (89.4%) of which were histologically confirmed. Histology confirmed 88.5% of the cytologically diagnosed adenocarcinomas. Washing cytology detected two confirmed tubal adenocarcinomas that had not been detected by curettage.
