@spooz2, your experience Tuesday with hematuria has similarities to mine on a dozen occasions over the last few years -- showing up without warning, sometimes producing small clots the size of a pea, sometimes recurring with urination for a couple of days, then just "switching off," as you said. When it first occurred about 8 years ago -- 2 years after surgery to remove a dozen papillary tumors and excess prostate tissue from inside my bladder -- my urologist reviewed his surgery notes as well as the first half-dozen cystoscopy exams of my bladder linings, residual prostate tissue, and urethra and found no graphic evidence of a source of blood. Finally, he noted that the blood in my urine was diluted quite a bit, not "frank" or thick as it emerged. At his suggestion, we agreed that the dilute blood -- even accompanied by a small clot or two -- probably had "leaked" from tissues in my bladder and that urgent emergency care could be avoided if the pinkish urine cleared up in a couple of days. So that's a normal part of my life since then (I had another incident just last week). Did your radical cystectomy leave you with an entirely different situation than mine, with my bladder still intact and functioning?
