Abstract

Background: Benign Prostatic Hyperplasia (BPH) is a non-malignant prostate gland enlargement that produces lower urinary tract symptoms in older men. This study investigates the Resistive Index (RI) of blood flow in prostate patients diagnosed with Benign Prostatic Hyperplasia (BPH). It compares the RI values of patients with obstructive BPH, non-obstructive BPH, high Prostate-Specific Antigen (PSA) levels, and aberrant prostate size. Materials and Methods: The study studied 80 male patients aged 50-85 with benign prostate hyperplasia and lower urinary tract symptoms during 8 months. Results: The blockage rate was 65% out of 52 patients, with 35% not having it. An obstructive pattern was shown by the markedly elevated resistance index of the right and left capsular arteries. Prostate Specific Antigen (PSA) values were high in 74% of patients and low in 26%. Additionally, PSA levels were directly impacted by the enlargement of the right and left capsular. Conclusion: The RI measurement using prostate Doppler ultrasound can be added to the modalities available for diagnosis of BPH. Moreover, its value can be correlated to the prostate size, prostate-specific antigens, and degree of obstruction.
