Abstract: Lower Urinary tract symptom (LUTS) is a common presentation among elderly patients particularly in men in urology clinical practice. Evaluation and treatment of LUTS is a major consideration and IPSS score and ultrasound KUBP are routine investigations for assessment of such patients. There is a controversy on relationship between IPSS score and the prostate volume in the literature. The objective is to evaluate the relationship between IPSS and prostate volume in patients with LUTS. There is a significant relationship between IPSS and prostate volume measured through abdominal ultrasound. The Total IPSS increases with the prostate volume (r=0.223, p<0.003). But there was no statistically significant difference between mild, moderate and severe IPSS in relation to prostate volume.
