my husband, age 72, had to be taken to the ER last Wednesday with stomach pain and had been having trouble for about a month empting his bladder. Ultra Sound showed thickening of wall of bladder, and when they put a catheter in there was over 1 1/2 liters of dark urine that came out. He is sill on a catheter and scheduled for another US/CT on Tuesday. No fever and not sign of infection. The scan at the ER found a few cysts on his kidneys. He is a fit person, sr Olympian , and almost never sick. He has lost about 8 lbs over the past month or so...give or take a pound or two. The Urologist plans to scope after this next Ultra Sound.
