Purpose: The aim of this study was to evaluate the reliability of 1-day frequency-volume charts in assessing lower urinary tract symptoms (LUTS) in patients with benign prostate hyperplasia (BPH).
Materials and Methods: Between Jan. 2006 and Dec. 2006, we retrospectively analyzed the medical records of men with LUTS due to BPH who visited our out-patient department. All of 70 men completed 3-days frequency-volume chart for the initial evaluation of their LUTS. We compared mean values of variables with values from respective days. Test-retest reliability was evaluated by calculating intraclass correlation coefficient.
Results: The mean age was 66.7 years, mean prostate size was 33.6ml, mean IPSS was 18, and mean maximal flow rate was 13.8ml/s. The mean total voided volume was 1716.3ml/day, mean number of voids was 9.2/day, mean number of daytime voids was 7.1, and mean number of nocturnal voids was 2.0. No significant differences were found between the three 24-hr periods for the variables from the charts by ANOVA test. The intraclass correlation coefficients were mostly 0.7-0.9. But nocturnal bladder capacity was slightly less reliable than other variables, 0.557. Mean voiding volume, total voiding number, and daytime frequencyhad the high reliability.
Conclusions: A 1-day frequency-volume charts can be sufficiently reliable to provide an insight into a patient’s voiding behavior. But more research of high quality is required, especially into the relationship of frequency-volume charts duration with compliance
