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<0.001), IPSS (p<0.001), prostate size (p<0.001), PSA level (p<0.001), and voided volume (p<0.001). Qmax decreased with increasing age, IPSS, prostate size, and PSA, but increased with larger voided volumes.

CONCLUSIONS This large-scale community-based study provides valuable insights into the relationship between uroflowmetry results and various factors in adult males. These findings can serve as a reference for evaluating uroflowmetry results in clinical settings and contribute to a better understanding of lower urinary tract symptoms in the general male population.
