Flow chart of study selection for inclusion in this review. *1 Five papers were included via manual search. Three of those do not report on combination therapy, but were considered relevant by the authors (Andriole et al., Marberger et al., Bent et al.). One was published in Japanese, and only available as a translated reprint (Saito et al.). And one was published in a journal (LUTS) that is not listed in PubMed yet (Nishizawa et al.).
