✦ Synopsis

To assess the validity of classification of urinary flow curve patterns, six doctors at different levels of urtxlynamic education were asked to ify 176 urinary Plow curves. The curveb had been obtained from elderly, randomly selected men without voiding problems. Five flow curve patterns were defined both graphically and in writing, and the six observcrs were asked to classify the 176 curves into one of the five categories.

The agreement between the six observers was calculated as a frequency, and this value was corrected for the chance agreement. Some of the observers were asked to reevaluate the curves after 3 months, and the interobserver variation was calculated.

We conclude that if of any value, the classification of urinary flow curves must be undertaken by urodynmically trained persons. In that case there is a good chance that the classification can he reproduced by any other urodynamically trained person.
