Cooper is an 11 yr MI Lab who’s initial presentation did include some blood from the penis, but no difficulty urinating (presented for other reasons).  Rectal exam revealed smooth, non-painful prostate.  UA consistent with a UTI and hematuria.  Blood work unremarkable.  Ultrasound of prostate revealed very enlarged prostate (5 cm) with mottling, some smaller cystic areas, one area of shadowing and inc. opacity and some asymetry.  Placed on Baytril for 2 weeks.

Unfortunately, did not get enough cells on sample to feel like we ruled out neoplasia.  Did culture what I got and it was negative (had been off antibiotics about 5 days).  Asymptomatic.  We had resumed Baytril pending results.  Leaning towards continuing the Baytril, scheduling neuter, leaving him on Baytril about a week of so after neuter (would normally do longer, but w/ negative culture, wondering if longer is necesssary) and re-ultrasound a month after neuter.  Other options, FNA or repeat prostatic wash.  Thoughts? Before and after Baytril photos and cines provided.
