Sensitivity of exfoliative cytology in bladder cancer using the divided one-urine specimen 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.
