Medical therapy for relief of symptoms of benign prostatic hyperplasia (BPH
) is now a clinical reality. The challenge for urologists treating BPH with
medical therapy is how to rationally employ the two proven classes of medi
cations, the alpha blockers and finasteride, in their practice. To accompli
sh this, we must critically examine the results of multiple important clini
cal BPH trials published over the last decade and examine the short and lon
g term effect of the various available medical therapies on symptoms, objec
tive progression and consequences of the disease process and whether eviden
ce based indicators will allow us to choose appropriate therapies. It appea
rs that we can rationalize our medical therapy decisions, taking into consi
deration severity of disease, prostate size (and perhaps PSA) and most impo
rtantly, the patients' longterm expectations for treatment outcome. But fir
st physicians must decide for themselves whether to expand their treatment
paradigm beyond short term symptom relief to encompass long term durability
and even prevention of the consequences of the long term progression of BP
