How to clear up a UTI fast?!

UPDATE BELOW: I have a surgery tomorrow to clean out my kidney from PCNL a month ago and take the stent out. I was called at 4:30pm today to tell me that they called in antibiotics for an infection I apparently tested positive for over a week ago! And then not an hour later the doctor doing my surgery calls and says if the infection isn’t cleared up “enough” to do the surgery they will cancel it and reschedule it. They have put it off long enough now. This was supposed to have been done weeks ago. My urologist clinic is a nightmare. So besides the antibiotics is there anything I can do to clear my infection up “enough”? I really need this stent out. I’m desperate.

Update: I sat in the hospital room for 5 hrs while they debated on doing my surgery or not. I was sent home. No surgery. My infection was too bad to do surgery. I’m devastated. I really needed this surgery to happen. But I just pray they get the surgery rescheduled to a date that’s not too far away from now. I only have 11 tablets of antibiotics left. And from past experience, the UTI always returns shortly after finishing them.
