The paper evaluates the usefulness of cytologic examination of urine sediment performed by millipore method, based on 125 cases. The method permits high quality cytologic smears obtained even from cellularly poor urines. The sensitivity of this analysis is directly proportional to the histological grade of the tumour. In the case of transitional cell carcinoma G1, the sensitivity was 65%, in G2-79.3% and in G3-92.9%. High sensitivity of this examination was found in carcinoma in situ. Our study is of retrospective character, the results presented were obtained on the basis of one cytoanalysis of urine sediment.
