[Efficiency of phosphodiesterase-5 inhibitors for treatment of lower urinary tract symptoms in patients with benign prostatic hyperplasia and concomitant erectile dysfunction].

Lower urinary tract symptoms (LUTS) in combination with benign prostatic hyperplasia and erectile dysfunction are more common than commonly thought. Unfortunately, urologists often dont ask about concomitant erectile dysfunction in patients with irritative or obstructive symptoms, which leads to the progression of underline disease, a deterioration in the quality of sexual life, and, as a result, overall quality of life. The relevant studies of recent years dedicated to feasibility of using tadalafil 5 mg a day are analyzed in the article. In addition, the results of scientific work conducted on the Department of Urology and Andrology of Faculty of Fundamental Medicine of Lomonosov Moscow State University, whose aim was to study the efficiency of phosphodiesterase-5 inhibitors in patients with LUTS of varying severity in combination with other types of drugs, are presented. Tadalafil in a dose 5 mg leads to a decrease in the severity of LUTS, as confirmed by a decrease in the mean I-PSS score by 2.19 points in the presented studies. No significant changes were found in Qmax (>0,05). We also proved in our work that phosphodiesterase-5 inhibitor can supplement any combined therapy for benign prostatic hyperplasia in the case of concomitant erectile dysfunction. Tadalafil in a dose 5 mg once a day can be recommended as monotherapy for patients with moderate LUTS caused by benign prostatic hyperplasia with concurrent erectile dysfunction, as an alternative to conventional treatment schemes.
