Although International Prostate Symptom Score (IPSS) is widely used for LUTS assessment, the Visual Prostate Symptom Score (VPSS) is hypothesized to offer a more rapid and patient-friendly assessment, therefore this study was conducted with the aim to evaluate the correlation and agreement between the VPSS and IPSS in all male patients ≥40 years presenting with LUTS.

A prospective, cross-sectional study included 200 consecutive male patients presenting with LUTS at our urology OPD after obtaining informed consent.. Participants completed both the IPSS and VPSS questionnaires during the first visit. Pearson’s correlation coefficient (r) was used to assess the correlation between the total scores. Bland-Altman plots and intraclass correlation coefficients (ICC) were used to analyze the agreement between the two instruments. Subgroup analysis was also conducted based on severity of LUTS according to IPSS.

The mean age of the participants was 60 ± 5 years. The mean IPSS score was 19 (scale 1-40), and the mean VPSS score was 13 (scale 4-23). A strong positive correlation was observed between the IPSS and VPSS (r = 0.88, p < 0.001). The ICC was 0.90, indicating excellent agreement. Subgroup analysis demonstrated consistent strong correlation and excellent agreement between the VPSS and IPSS across mild, moderate, and severe LUTS groups.

The VPSS demonstrates a strong correlation and excellent agreement with the IPSS. Considering the differing scales, the mean VPSS and IPSS scores show comparable relative positions.
