RESUMEN
We have collected urine specimens from cases of malignant and nonmalignant lesions of the urinary system and have proceeded to a comparative study of these cases with their clinicopathologic findings after staining them with the Papanicolaou method and the fat stain method. It was found that the fat stain is not specific for renal cell carcinoma only. However, a combination of fat stain and Papanicolaou stain as a second check up of potential malignancy would be the best way of examination.

The urine of 104 patients with bladder cancer was examined by exfoliative cytology. Three staining methods (Giemsa, Papanicolaou and Oil Red O) were used and the results compared with the histological diagnosis. Giemsa was found to be superior to the other two methods but the highest sensitivity (which was statistically significant) was obtained by a combination of the three methods.
