Correlation between body mass index and prostate volume in patients with benign prostatic hyperplasia

Introduction. Obstruction due to benign prostatic hyperplasia (BPH) is a common condition in men over 40 years of age. This study determined the association between body mass index (BMI) and preoperative prostate volume (PV).The purpose of the study was to determine whether there is an association between obesity and prostate volume in men with BPH.Materials and methods. The medical records of 96 patients who underwent holmium enucleation of the prostate as a treatment for BPH and who met the inclusion criteria were retrospectively reviewed. The mean age of the patients was (70.6±8.5) years. Correlation analysis was performed to assess the relationship between BMI and prostatic volume.Results. A total of 96 patient charts were analyzed. When assessing the relationship between BMI and prostate volume, a statistically significant direct correlation of moderate strength was found (ρ = 0.456, p < 0.001). Patients with prostate volume > 75 mL were significantly more likely to have urinary retention (p < 0.001; OR = 4.7; 95% CI: 1.9−11.4).Discussion Studies on larger patient samples are needed to verify the results against true population figures.Conclusion A positive correlation between BMI and prostate volume has been established.
