Bladder diary measurements in asymptomatic males: Frequency, volume per void, and 24‐Hr volume

Abstract

Our results suggest that reference values of F(24) and Vol/Void should be adjusted for their relationships to the patient's age and V(24). Regression equations expressing these relationships can be used to make these adjustments. From frequency histograms of residuals the difference between the patient's actual and expected reference measurement can be ranked within the reference population as a percentile. We illustrate this method by using our results to calculate age- and V(24)-adjusted 5% "normal limit" tables of F(24), V(avg), and V(max).

The optimal duration of frequency‐volume charts related to compliance and reliability

“…The “true frequency” is still based on patient report, by recording coded letters. Mean urine production, however, is comparable with other studies . Other types of voiding diaries that include urgency scales or fluid intake, might show different compliance rates.…”

A Cutoff Value Based on Analysis of a Reference Population Decreases Overestimation of the Prevalence of Nocturnal Polyuria

“…An adaptive mechanism of the bladder to larger volumes was previously suggested. 6,7 The NPI increased 0.6% with each 100 ml decrease in 24-hour urine output. Obviously lower 24-hour volume would lower daytime volume while nocturnal volume would remain unchanged or show a much smaller decrease than daytime volume.…”

A randomized, controlled trial of effectiveness and safety of management of OAB symptoms in elderly men and women with standard-dosed combination of solifenacin and mirabegron

“…Examination began with urodynamic test (n = 239) which was repeated for all patients (n = 232) at the end of followup, except for patients who refused from treatment due to intolerable side-effects (n = 7). After filling in standard OABq-AT questionnaires (signs of OAB if the total sum exceeds 8), recommended by ICS all patients had been keeping bladder diaries where they daily recorded amount of single urination, number of urinations per day, number of urgencies, and number of EI (Parsons et al, 2007;Tissot, Amundsen, Diokno, Webster, & Coats, 2008) during 3 months. In a month after the study had begun patients started taking medicines and placebo (6 weeks).…”
