What could cause billiroubin to be expeled in urine?

I had a UA dip done today and they found billiroubin (sp) in large quanities in it.. she reviewed the one I had last week and it too showed it in large quantities.. she tried to explain to me after telling me that it wasn't normal, what it was.. and I got that.. but can this be a side affect of surgery or what else could cause this.. I am about 6 1/2 weeks out.
