You are not giving us a lot to go on. Given the information you've
given I can say that -regress- (assuming that that is what you're using
for your "one level regression") is in the list of supported regression
commands of -micombine-, and -xtreg- is not. -xtreg- might still work
though, this just means that it hasn't been tested. As for descriptive
statistics you can just the mean of the descriptive statistics over the
five "complete" datasets. 

A nice FAQ (not Stata specific) on Multiple imputation is:
http://www.stat.psu.edu/~jls/mifaq.html

If you want more help, you have to give us more information about your
problem. There is lots of useful advise on how to formulate your
question on:

Hope this helps,
Maarten
