Was catheterized 12/6 in pm for urine retention and given flomax (tamsulosin). is it normal, when not drinking a lot to still be producing like 900 cc's of urine in a 4 hr time frame 2-3 days later?

Urine volume: 225 cc an hour is a lot of urine, but withouot more information about your medical condition and what your dietary intake was prior to measuring your output it is difficult to comment on. It is not impossible for this to be normal under some circumstances, but if this remains constant go back and discuss with your doctor.

Hhmm: Flomax (tamsulosin) is meant to work on folks with prostates... If you had surgery or received IV fluids during what sounds like a hospitalization, the body usually starts to get rid of the excess fluid 3-4 days later, as you get better. Makes sure your blood sugar is ok, since that can make you go more than you should. Sometimes after retention kidneys can't retain water well.
