whisky stone

The most common of urinary stones is the €calcium oxalate stone€. These are speckled, mace like and barbed stones which stick and cut on their way out of the kidney after being dislodged. This sounds scary, but usually isn't very painful, although, sometimes very uncomfortable. Uric acid and other stones can do this too.
What you should understand is that the greeters, the tubes that connect the kidneys to the bladder, although very tough, and can withstand squashing and stabbing, do not do well with distension. If a stone lodges somewhere in this tube on its way down, the result is urinary distension behind the stone and excruciating pain described by some women, as intense as the pain of end stage labor contractions! This condition is called €hydronephrosis€ and is the real center of kidney stone pain.
