 Several studies have attempted to define how best to predict for and treat these symptoms. However, the incidence and severity of these symptoms is difficult to predict.

The aim of this study is to compare outcomes of urinary morbidity following prostate brachytherapy between patients treated with alfuzosin prior to implantation and patients treated following implantation.
