Yes: Cocaine is metabolized in the liver and metabolites are excreted in the urine where no additional metabolism takes place.

Many determinants: While there is no clear information on this subject, one study tried to quantify metabolites in urine and blood from illegal substances. Depending on how the drug was used as well as the amount determines how long the metabolites are noticed in the urine. Most cocaine metabolites were found in the urine from 1 - 3.6 days
