After a prostatectomy if no cancer remains in the body, the PSA is usually espressed as a "less than" > number. My pathology comes back as Less than .01. Expressed as >.01 Sometimes pathologist use other numbers to express the same thing.
When your urologist says it is negative he is probably referring to these numbers.
Maybe you can get the pathologist to explain what your psa numbers mean.
