My father had uti or prostatitis 4 months ago and catheterized up until 2 mnths ago and no prblm now bt his urinalysis shows amorphous phosphates 2+, alkaline turbid urine with 1-2 pus cells and nothing else. how can these crystals can be controlled?

Normal urinalysis: This is your second question about this. As discussed previously, phosphate crystals are normal in the urine; there is no need or reason to do anything about them. The important thing is that your dad has no UTI at this time. Discuss with his doctor (or as your dad to do so) if you remain concerned. Don't let yourself be obsessed by meaningless urinalysis results. Nothing is wrong.
