Urine is a mixture.

I'm pretty sure your urine should smell like urine. Why are you smelling your urine?

When urine can't leave the bladder it's called urine retention. This can be caused by some medications, but it can also be from something serious. It can also result in reflux, meaning the urine backs up into the kidneys. When urine retention does happen, you need to see your doctor for a diagnosis and treatment.
