[Analysis of frequency volume chart in elderly people with pollakisuria. Comparison between the elderly and the adult].

Based on the frequency volume chart, 215 patients who complained of pollakisuria were clinically investigated. The subjects were divided into 2 groups: the elderly group was composed of 85 patients more than 65 years of age (mean of 72) and the adult group comprised 130 patients less than 64 years old (mean of 47). The elderly group was characterized by the fact that, during nighttime (after sleep), their urinary volume was larger, each voided volume was smaller and the number of voiding was greater than the other group. Clinical analysis of the causes of pollakisuria enabled us to subdivide them into 6 diagnostic categories. Among the elderly patients polyuria during sleep and unstable bladder were prevalent and among adult patients unstable bladder and over hydration were common. Medication was made in 80 patients (37%), while 108 (50%) needed neither medication nor surgery. It is stressed that the frequency volume chart is one of the important diagnostic tools to evaluate the cause of pollakisuria and to select appropriate treatment.
