title: Concealed haematuria--whence cometh the bleeding? A new method of localisation.
abstract: Concealed haematuria is often a difficult diagnostic problem. A method for collecting isolated urine specimens from different areas of the urinary tract and subjecting them to quantitative analysis for RBCs is described. A more accurate localisation of the source of bleeding with, in the upper urinary tract, side differentiation, is thus possible. Some examples are presented as case reports.
