The pathophysiology of lower urinary tract symptoms (LUTS) is multifactorial. The fact that none of the available drugs impacts on more than one of these pathomechanisms, provides the rationale for combined medical treatment strategies. The combination of α-blocker and a 5-reductase inhibitor is recommended by all major benign prostate hyperplasia (BPH/LUTS) guidelines as a first line approach for men with moderate to severe LUTS and a higher risk for disease progression. The efficacy of this approach has been proven in prospective randomized trials for up to 4 years. The combination of α-blocker and antimuscarinics has been tested in several randomized trials as a primary approach or as add on therapy but the maximum study duration was only 3 months. The add on approach is suitable in particular for men with persisting storage symptoms under α-blockade. The risk for acute retention in appropriately selected men is low. The scientific basis for all other combinations is not solid enough to recommend the use outside clinical trials.
