INTRODUCTION AND OBJECTIVES: Differences in ethnicity and geographical factors may have an effect in the characteristics of the prostate in men. To date, there is no demographical data regarding the average prostate volume among Filipino males stratified per age. METHODS: Retrospectively collected data from 3568 consecutive patients who had an ultrasound of the prostate from January 1, 2015 to December 31, 2016. Age and prostate volume by ultrasound were collected. Patients who had previous prostate surgery were excluded, and for uniformity of results, only patients who underwent transabdominal prostate ultrasound were included. RESULTS: Patients were stratified into the following age groups: 29 and below, 30 to 39, 40 to 49, 50 to 59, 60 to 69, 70 to 79, and 80 and above, and present results showed that the mean values of prostate volume were 15.8 ± SD 5.4, 19.6 ± SD 5.7, 22.1 ± SD 7.3, 28.0 ± SD 11.0, 34.0 ± SD 17.9, 39.6 ± SD 28.13, 39.2 ± SD 23.3, respectively. CONCLUSION The mean prostate volume among Filipino males increases with age and the threshold for an enlarged prostate might need an adjustment in dealing with Filipino patients.
