A Simple Workaround
for Kidney Stones

Julio M. Otuyama (alumni.usp.br)

Urinary system Kidney Stone is a painful disease. But it does not need to be this way. The trick is to keep the bladder near full. That means, when one needs to urinate, do it "just a little" (stop before the end). This creates a pressure about the same of the blood, in the whole (kidney / bladder) system. When a crystal (of kidney stone) is under pressure it can hurt the tissues [1]. Otherwise, it is harmless [2].

As a matter of fact, when one drinks water to get drugs (for kidney stone pain), maybe the water is helping more than the drug. 		Surface of a kidney stone
