Ureteric colic is a pain due to the passage of a stone through the ureter.
Ureteric colic starts suddenly with pain in the loin. The pain radiates from the affected ureter to the front of the abdomen and down to the groin. Occasionally it can also radiate into the testicle in a man and to the labia in a woman.
The degree of pain is very severe. The patient becomes very restless and uncomfortable and may want to lick the room. Typically each episode may last for half to one hour. It is often spasmodic and tends to come and go with an hour or two between attacks. The pain is caused by the stone passing down the ureter or due to its trial to pass down.
The pain is so intense that the patient may have nausea and vomiting. There may be a rise in temperature if there is an associated urinary tract infection.The stone lodged in the very lowest part of the ureter may cause marked urgency to pass urine. Anatomically, the last 02 cms of ureter are in the bladder wall. The irritation produced by the stone in the bladder wall causes the urgency to urinate.
Abdominal examination may be unremarkable. There may be no tenderness except the severe pain. Tenderness is elicited in the presence of infection along with raised temperature.
