Clinical background:
Cellular examination to exclude or confirm presence of malignant cells. A mid-stream urine (M.S.U.) is usually collected, preferably about 30 minutes after a morning drink. Bladder Washing
These specimens are received from urology clinics from patients suspected of having bladder tumours (which project papillae like into the lumen of the bladder and exfoliate cells into the urine). The procedure consists of introducing a cystoscope into into the bladder through the urethra then flushing the bladder out with isotonic saline (in a similar way to obtaining a lavage specimen) then aspirating the saline plus cells into a washout container.
