I had cancer 7 years ago uterus and breast cured now. Had a full hysterectomy. The other day I peed lots of blood. Came back not a UTI. Went for bladder scope was good. My culture showed high blood white count. Today I go for a CT urogram wonder what they will find and what they are looking for!!! Also have lower abdominal cramps.
If your cystoscopy was good then I would guess they are looking at your kidneys as they can cause blood in your urine - it could be kidney stones. I had ct urogram and really didnt like it when they injected the fluid in the veins. Good Luck xx
