There is a specific sharp pain caused by the passage of the stone through the small valve which opens into the bladder. This pain can be extreme, even with smaller stones, but it is usually very short in duration. As the stone presses through into the bladder, there may be a series of sharp stabs over several minutes until it bursts free. Fortunately, once in the bladder, most stones cause very little pain, and usually pass in a stream of urine after a few hours or after a night's sleep. Surprisingly enough there is usually no pain involved when the stone passes through the ureter of a male.
Men get stones more than women.
