Your vet might be worried about a urinary tract infection and may want to get a sterile sample to send out for a culture through a procedure called a cystocentesis. In this procedure a very small needle is advanced into the bladder, sometimes using ultrasound guidance. It is a very common procedure in veterinary medicine. Diabetic animals often have 'quiet' urinary tract infections that are not obvious on a typical urinalysis and a urine culture to look for bacteria is often more helpful. A urine culture also helps determine what antibiotic the bacteria are susceptible to. Performing a culture on a 'free catch' sample that you would bring in might not be helpful since contaminant bacteria from the lower urinary tract can be in the sample.
