Background: Benign prostatic hyperplasia (BPH) is one of the primary causes of morbidity in older adults. Without timely intervention, the risk of developing urinary obstruction is 2.5% higher in men with BPH. Prostate size or volume and reduced urinary flow rate are significant predictors of prostate obstruction and can be visualized on a real-time basis using ultrasonography (USG). Aims and Objectives: To evaluate the relationship between prostate volumes (PV) and post-void residual volume (PVRV) to predict the degree of obstruction. Materials and Methods: A tertiary care center in Gujarat studied fifty symptomatic and asymptomatic male patients with BPH (age ≥50 years) were studied at a tertiary care center in Gujarat. Sociodemographic details were recorded. The prostate size was measured by planimetric USG with the patient resting in a lateral decubitus position. Post-void residual volume was assessed with transabdominal USG. Results: Mean age of patients with BPH were 62.78±12.56, the majority being 51- 60 years (48%) of age. PV showed a significant increase in mean size in different age groups (P70 years age group was 54.82±18.21, 68.26±12.28, and 112.42±8.34 respectively (p<0.001). On Pearson correlation a significant positive correlation was obtained between prostate size and mean PVRV (p=0.001, r=0.575) and between age and PVRV (r = 0.623, p = 0.008). Conclusion: Post void residual urine volume and PV using USG can serve as a novel accurate non-invasive test for predicting prostate obstruction in patients with BPH in decision making. USG provides real-time transabdominal scanning and has no risk of ionizing radiation like other methods.
