[|Human|] I am a 67 male and suppose to go into surgery in the morning to remove a large kidney stone that will not pass, but since this morning I have the urge to go urninate but cant, I dont know what to do, go to the er or wait until in the morning... thank you gene
[|AI|]  The large renal stone can cause urinary tract infection, not just the kidneys, occasionally it may cause inflammation of the urinary bladder too. This would cause the urge to urinate, however it may not be due to the presence of urine, but the inflammation. If you feel that the urinary bladder is distended and cannot urinate, please visit the ER now itself. If not you can wait till tomorrow morning, when you are posted for the removal of the renal stone. The urologist can examine and do what is necessary in this regard.
