DNA extraction from urine-Molecular Biology

Does anyone have expereince of extracting DNA from urine? I am having problems with this. I have previously extracted the DNA but then it degraded very quickly and since then I havent even been able to extract DNA. I have been using a Qiagen extraction kit that is suitable for urine. without any success. Can anyone help?

Urine must always be charged with 15 ug/ml proteinaseK to prevent destruction of DNA by lurking nucleases. It can be removed with phenol later.
