There are several methods to do a biopsy including laparoscope- needle biopsy, catheter biopsy just to name 3. All will require Simba be put under anesthesia- so it will depend on whether your vet thinks she can handle it - and if you are willing to accept the possibility she won't. I am so sorry I couldn't come up with anything else. You can also see how she continues to do with the antibiotics- ask your vet if adding venoquil methigel would help -especially if there were any crystals in the urine. You can get that thru Chewy. I have several kitties on it to keep their crystal/stone formation down (especially since she is passing clots you don't want a stone to act as a plug. There may be other drugs he could add that could help break up a clot. Also switch her to wet food only.
