Benign prostatic hyperplasia (BPH) and chronic prostatitis (CP) are among the most common causes of LUTS in men. LUTS occur on average in 62.5% of males, with irritative symptoms occurring in 51%, obstructive symptoms in 26%, and postmicturic symptoms in 17% of cases. According to the literature, moderate and severe LUTS were observed in 13% of men under the age of 50 and in 28% after 70 years. It should be noted that LUTS are not BPH-specific, since may be caused by prostate inflammation. According to publications, 57% of patients examined for CP have BPH, and 39% of patients with BPH have CP. The first line of drug therapy in patients with BPH is currently considered to be alpha-blockers and inhibitors of 5-a-reductase. In addition, it is possible to use herbal preparations made from fruits, roots, seeds, pollen and plant bark. Preparations based on Serenoa repens extract are among the most studied and are widely used both in our country and worldwide for the treatment of patients with BPH and LUTS. Only lipidosterol hexane extract of Serenoa repens is recognized as a drug, the use of which has a good evidence base. The clinical examples illustrating the pharmacological properties and results of the use of the preparation of lipidosterol hexane extract Serenoa repens are presented in the article.
Conclusion. The presented clinical cases demonstrate the efficiency of the hexane extract of Serenoa repens fruit for the treatment of LUTS associated with BPH and CP. At the same time, the drug can be effectively used both as monotherapy and in combination with alpha¬blockers. Therefore, it is reasonable to use the hexane extract of Serenoa repens fruit in clinical practice for the treatment of LUTS associated with BPH.
