RESULTS	Although RARC was associated with longer operative time ( p < 0.001 ) , patients in this group might benefit from less overall perioperative complications ( p = 0.04 ) , more lymph node yield ( p = 0.009 ) , less estimated blood loss ( p < 0.001 ) , a lower need for perioperative transfusion ( p < 0.001 ) , and shorter length of hospital stay ( p < 0.001 ) .\
