If I don't drink water in a six-hour period, I get blood in my urine. When I drink lots of water, my urine gets transparent.

I am 28 years old and have been drinking heavily for approx. 12 years. I wet the bed fairly often involuntarily after having drank heavily, and the other morning I woke to discover noticeable blood in my urine. What could cause this? I have no money, no job, and can't afford to have it checked out right now. Could it be effects of drinking for years, like a kidney or liver problem? Other than my drinking problem, I consider myself healthy, with very rare illness.

Blood showed up in my urine suddenly this Saturday morning. There were no warnings and no symptoms. It has been there continually throughout the day, whenever I urinate. I'm on Coumadin, and I think I've been prescribed an excessive amount. I plan to have a ProTime test Monday and then talk to my cardiologist. The next step would be a visit to a urologist, but I have a strong hunch that blood thinning is the cause.

I regularly have blood in my urine, although it is not seen with the naked eye. It is diagnosed when I have a physical, admitted to hospital for other things, etc. I have been to a urologist a few years ago, and they said nothing was wrong at that time, but it continues.

I have a complete duplex system on one side of my kidneys. For the past 14 months I have had constant blood in my urine, sometimes it's visible to the naked eye and other times it is only visible microscopically. No infection is found.

My son is only eight; he has had a significant amount of blood and protein in his urine for over five weeks. He has been through two ultrasounds, a CT scan, and lots of blood work. He has moderate lower abdominal pain that comes and goes and he has been complaining of vision problems. He has seen four doctors and is scheduled for two more. Still no diagnosis.

I am a 51 year old male, after working outside all day, when I get home and go to bathroom my urine has a bright red tint to it.

I have had burning and pain on urination for a week. Treated with ABX and Pyridium the symptoms persisted. Yesterday, I put a warm wash cloth on the area of relief and bright red blood was on the cloth.

I had a very big discharge of blood and brown mush. In afternoon I felt shivery/funny/dizzy. At 18.00 I noticed slight burning when urinating, but the urine was clear and pale as normal. Pain got worse but at 23.30 bed time urine was still clear and normal. In bed I felt very uncomfortable between my legs and made several trips to bathroom to see if I needed to pass a stool but didn't. At 23.50 I urinated bright pink with blood clots. At 23.55 I urinated bright pink with a lot of brown mushy bits and blood clots. While waiting for ambulance and in A&E I urinated about 15 times with the same pink urine, diminishing amount of brown mush and blood clots. Doctor examined me and diagnoses urine infection and gave me Trimethoprim. Bye 06.00 urine was clear and faint brown. By 09.00 it was clear and pale yellow. At 10.00 it was back to normal clear. The whole episode took just about 15/16 hours but the quantity of blood and brown mush was terrifying.
