Doctor, here's my report for my IVP examination.
Let me have a look. Can you see there's a stone in your kidney?
Oh, yes, is it dangerous?
No, but it's painful.
Do I have to have an operation?
No, it's not necessary since the stone is not big.
Good, I can still attend the Olympic Games.
Yes, you're lucky. But you should go to the Ultrasonic Department to disperse the stone. Meanwhile, I'll give you some herbal medicine.
