Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: Urology - gross hematuria, pelvic pain, no UTI?33F, overweight, white, Canada. History of kidney stones (4 in the last 18 months). Not taking anything to prevent them but Ive reduced sodium and drink a lot of water.In the last 2 months or so Ive had 2 instances of long-ish periods of time where I have visible blood in my urine (sometimes enough that it resembles menstrual blood and other times the tissue is just pink when I wipe) along with abdominal pain and sometimes flank pain. Both times Ive been treated with antibiotics but Ive had negative urine culture. Urinalysis showed blood, mucus and bacteria a couple months ago but Im not sure what my most recent showed. Ive now had blood in my urine since June 26th and what feels like menstrual cramps. I pee fairly often and get up a couple times a night. My last 24 hour urine collection showed big improvements and my kidney ultrasound looked good.Is there anything else this could be besides a UTI? Im hoping my urologist follows up after she called in antibiotics on July 7th.. ### Response: How were the urine samples collected? I really hope that they didn't just give you a cup to pee in.Macrohematuria in women can be caused by many things, the most common: hemorragical cystitis (infection) or urolithiasis (not just kidney stones but ureter stones or bladder stones) or an urothel carcinom of the bladder/ureter/renal pelvis, rarely but possible with RCC or a urethral caruncle.
