[Treatment of LUTS in BPS. When and when not to administer pills?]

Abstract

Benign prostatic syndrome (BPS) is considered a diagnosis of exclusion and needs a thorough work-up. One of the pitfalls for a tailored medical treatment scheme is the objective evaluation of benign prostatic obstruction. Characteristics of the various medical therapy options and the multifactorial origin of LUTS in BPH patients imply an individualized approach. LUTS involving mostly urine storage disorders and a small prostate are suitably managed with alpha(1)-receptor antagonists, which may be combined with antimuscarinics if OAB symptoms predominate. Long-term treatment addressing clinical progression may favor combination therapy of alpha(1)-receptor antagonists with 5alpha-reductase inhibitors if prostate size is sufficient. Age, symptom severity at baseline, a large prostate volume, or a high PSA value are indicative of progression. However, combination therapy aggravates side effects, and thus a risk-benefit analysis is essential. The potential of any medication for BPS to treat obstruction is rather low. If deobstruction is the main aim of therapy, medical treatment is not suitable.
