How To Treat Acute Pain In Urinary Track Due To Kidney Stone?

I want to visit an Urologist today evening for my 44 year old brother having stone at his kidney and suffering from acute pain. It is reported by Sonography test that the said stone is passing towards the urinal track which is causing acute pain. May I visit Dr. G.G. Mukherjee today or get any consultation for his treatment. I am at Asansol or I may consult at Raniganj West Bengal only.Sourav.
