Fractionated urinary cytology in the follow-up of bladder cancer.
Cytological examination of voided urine is an established investigation in urological practice. In a pilot study of 50 patients with histologically proven transitional cell carcinoma of the bladder, urine cytology was undertaken on samples from the initial, mid-stream and terminal parts of the void. Analysis showed that although the cell density varied between the samples in some cases, no part of the void was consistently richer in benign or malignant cells and similar cell types were seen in every sample from any given patient. It was concluded that fractionated cytology did not improve the diagnostic accuracy of urinary cytology and that any sample of urine was suitable for cytological purposes.
