question for slavic experts

Even if romanians got a lot from slavic languages , there has
been too some loanwords from romanians to slavic populations.
I am interested if there is known a romanian word which ends
in "-tzi" and how was this one borowed by slavs?Normaly, there
should be no problem (I think) with "tzi" because the slavs
have too this "tz" in language like, so far I remember
"ulitza"=street or sort of .

But for beeing sure, I just would like to know for sure that
there was no change of this "tzi" or maybe simple "tz" from
romanian to slavic languages..
