A Wilcoxon ranksum test cannot show that 2 independent samples are from the

If you want to calculate confidence intervals for rank statistics, then
this can be done in Stata using the -somersd- package. A reference on this
is Newson (2002). A pre-publication draft of this paper can be downloaded
from my website (see my signature).
