We aimed to evaluate whether the prostatic capsular artery resistive index can be a parametric criterion in evaluating the efficacy of α-blocker treatment and the severity of the disease in patients with benign prostatic hyperplasia. The clinical and diagnostic investigation findings and the radiographic images were recorded during the treatment and during the application of procedures in the patients who presented to our hospital with lower urinary system symptoms. Then, these data and the information of the respective patients recorded in the hospital database were examined retrospectively. A total of 66 patients were included in the study. Of the patients, 36 with higher IPSS were recommended to be treated and had a mean resistive index of 0.68±0.09, and the patients with lower IPSS had a mean resistive index of 0.65±0.05. The difference between these two values was found to be statistically significant (p<0.05).  In 36 patients who were treated for lower urinary system symptoms, the mean resistive index before the treatment was 0.68±0.09. After the treatment, the mean resistive index decreased to 0.64±0.07. This decrease was statistically significant (p<0.05). The mean IPSS was 20.38±4.03 before the treatment and it decreased to 14.38±3.69  after the treatment, showing a statistically significant difference, similarly (p<0.05). We are of the opinion that the resistive index of the posterior capsular artery of the prostate gland is a parametric indicator to determine the severity of the benign prostatic hyperplasia and to assess the efficacy of the treatment with alpha-blocker medications.
