Background: Benign prostatic hyperplasia (BPH) is a common progressive disease in the male aging population. The present study assessed relationship between prostate volume and lower urinary tract symptoms. Materials & Methods: 80 male patients of lower urinary tract symptoms were selected and International Prostate Symptom Score (IPSS) was used for the evaluation of benign prostatic hyperplasia (BPH). All underwent ultrasonography of lower abdomen and the prostate volume of each patient was estimated. Results: Age group age group 30-40 years had 8, 40-50 years had 11, 50-60 years had 26, 60-70 years had 22 and >70 years had 10 patients. The difference was significant (P< 0.05). Prostrate volume (in cc) 20-30 was seen among 15, 30-40 cc in 22, 40-50 cc in 16, 50-60 cc in 5, 60-70 cc in 12, 70-80 cc in 7 and 80-90 cc in 3 patients. The difference was significant (P< 0.05). IPSS revealed mild cases in 26, moderate in 34 and severe in 20. Prostrate volume 20-30 cc had 5, 10 and 0, 30-40 cc had 6, 11 and 5, 40-50 cc had 5, 5 and 6, 50-60 cc had 1, 3 and 3, 60-70 cc had 3, 1 and 8, 70-80 cc had 4, 2 and 0 and 80-90 cc had 2, 1 and 0 respectively.
