Urinary incontinence is a major health problem. Simple methods of investigation are thus of great interest. For example, the frequency/volume chart is in common use, but the efficiency of this instrument in characterizing different conditions of incontinence does not seem to have been scrutinized. In this study the frequency/volume charts of 81 genuine stress incontinent women are compared to those of 151 women without complaints from the lower urinary tract. The total voided volume, the frequency of micturition, the largest single voided volume, and the variability of voided volumes are all shown to be statistically different in the genuine stress incontinent material from that of the normal material. If this is of importance from a differential diagnostic viewpoint is uncertain, as the overlap between the materials for all parameters is great.
