Analysis of uroflowmetry results in community-dwelling adult males: Results of 24 years of Korean population-based screening data

PURPOSE: In this study, we aimed to analyze the uroflowmetry findings in community-dwelling adult males and examine the relationship between maximum urine flow rate (Qmax) and factors such as age, prostate size, International Prostate Symptom Score (IPSS), prostate-specific antigen (PSA), and voided volume. MATERIALS AND METHODS: Data were collected from 75,199 males aged >24 years through community health screenings conducted by the Korea Prostate & Voiding Health Association. After applying the exclusion criteria, 12,891 males with complete data were included in this analysis. Uroflowmetry, IPSS, transrectal ultrasonography, and PSA tests were performed. RESULTS: The mean patient age was 74.66±9.10 years, mean IPSS was 14.59±8.11, mean prostate size was 30.50±14.44 mL, mean PSA was 1.79±3.94 ng/mL, and mean Qmax was 14.21±6.34 mL/s. Significant associations were found between Qmax and age (p
