Depends on the variety of Hydrangea - if its a macrophylla (mophead or lacecap type) then, no don't prune, and pruning in spring only consists of removing any spent flower heads and any obviously dead bits of wood in April. If its a paniculata variety, yes you can prune those back and they will still flower next year - unlike macrophylla, which won't if you cut them.
