Narrative:

On the day of this situation 2 legs of the trip were already completed. Our flight departed san francisco normally en route to las vegas. Approximately in the area of lidat intersection, the pilot in command (pilot flying) stated he was experiencing some discomfort in the lower left back area. Shortly after this, the captain requested that I fly the aircraft to a landing in las vegas. At approximately 50 NM from the airport, the captain requested an ambulance meet the aircraft as a precautionary measure. The remainder of the flight was conducted in a routine manner, all checklists accomplished, no deviations from flight profiles. On our arrival at the gate, the ambulance met the aircraft in a low profile manner, and after all passenger were deplaned the captain walked to the ambulance unassisted. An emergency was not declared as the captain was conscious at all times and remained in command/decision making authority. Because of the random factor involved in the situation, I cannot think of a solution other than personal judgement to correct the situation. Callback conversation with reporter revealed the following. There was no medical history of problems that anyone was aware of for the captain involved. First officer does not think the passenger were ever aware that the captain became ill and thinks this was his 1ST problem with a kidney stone.
