<s>[INST] I had Davinci robot removal of the prostate 13 months ago with good success but PSA went from .01, .02,,.05 and now .1. My regular doctor said after my blood test said I may have an infection-UTI. Since I have no prostate can infection cause my PSA to rise ? [/INST] Hi, I don't believe that infection in the urine can cause an elevation in the PSA because as you said you don't have any prostate anymore. But of course we have to hope for the best, so we will see I repeat PSA after you take the antibiotics prescribed to you. If there is still rising PSA after the course of antibiotics then we may say that you may have prostate cancer recurrence after surgery. Your doctor might give you hormone therapy or addition depending on your clinical data. Hope I have answered your query. Let me know if I can assist you further.  </s>
