Correlation between transabdominal sonographic prostate volume and anthropometric parameters

Background: Prostate diseases commonly present with lower urinary tract symptoms (LUTS) resulting from prostatic enlargement. Prostate volume (PV) can be evaluated using transabdominal ultrasonography. Focus is currently on relative factors of prostatic enlargement which includes obesity and central adiposity. The aim of this study is to correlate transabdominal sonographic PV and anthropometric parameters in patients with LUTS in Port Harcourt. Methods: This was a prospective cross-sectional study carried out at the Radiology Department, Rivers State University Teaching Hospital, Port Harcourt, between September 2020 and January 2021. One hundred and twenty (120) males from 40 years and above who presented with LUTS were recruited. Transabdominal PV estimation was done and body mass index (BMI) as well as WC was assessed. Data were analyzed using a Statistical Package for Social Sciences; appropriate statistical tests were applied and P < 0.05 was considered significant. Results: The mean PV was 69.8 ± 63.5 cm3, 79.2% of the subjects had enlarged prostate with volume ≥30 cm3. PV was found to increase with age. The correlation between PV and anthropometric measures of obesity (BMI and WC) was statistically not significant. Conclusion: The work established that there is no correlation between PV and anthropometric measures of obesity - BMI and WC in negro population as opposed to nonblack population where there is correlation. Obesity may not be a considerable risk factor of prostatic enlargement in the studied population. Thus, anthropometrics may not be useful in predicting prostate size.
