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

초록

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.
