Jim, I have often read that the acidification of urea application is fairly substantial  and a significant factor in apple production in acidic soils.  It wouldn't surprise me if urine has neutralizing minerals to counter the urea (horse stable waste comprised of urine-soaked pine shavings composts out to a pH in the mid sixes) but urea by itself is consistantly attributed to being acidifying. 
 
Are you aware of any specific chemical analysis of human urine in this regard?  I have used my own urine as a fertilizer for years with great success but I don't have to worry too much about pH in my slightly acid soil.  I heat with wood and use the hardwood ashes to keep my soil in a productive range.
