You : You haven't specified a timeline, so it's not clear how long you've been unable to urinate. If it's more than a few hours, that would suggest a problem that needs to be investigated. In a person with two kidneys, which is the norm, even complete obstruction of one kidney by a stone would not stop urine from being produced in normal amounts by the other. While it's possible that both kidneys could simultaneously be blocked by stones, it would be highly unlikely. If you really have no urine at all, the likely explanations would include: 1) the stone is blocking your urethra--that is, it has gotten past the kidney, into the bladder, and is now stuck between the bladder and the outside world; 2) the stone (or some other process) has caused bleeding into the urinary tract, and a clot is now blocking flow out of the bladder; 3) you only have one functioning kidney (which is more common than you might think, and might be the case without your knowing it) and that kidney is blocked by a stone or other process. Again, if you have produced no urine at all in a period of more than a few hours, you should go to the er for evaluation.

In : In some patients with distal ureteral stone, if pain is severe, it might cause urinary retention. If you feel your bladder is full and you are unable to urinate, you need to go to er for an evaluation. The only other reason would be that you are not making any urine if both kidneys are blocked. In eir=ther case, you need to go to er.
