The ultrasound shows that my right kidney measures 11.2 cm, the left 10.4 cm and they are both described as "unremarkable" ([]YAY[]).  What size range is normal for a person my size (105 pounds, or 15 stone, if a stone is 7 pounds)?  

I find it interesting that the right kidney is larger since that is the side that hurts sometimes (and the reflexology point that is more irritated).  Nonetheless, it's an acceptable level of discomfort, and I'm not worried, since I'm convinced that my body will continue to heal.

Thank you for your help[] in concluding what has been a seven year project.

You are probably thinking of a kidney stone rather than a gall stone.

What's the difference between them?

You are probably thinking of a kidney stone rather than a gall stone.

What's the difference between them?

A kidney stone accumulates in the kidney and is often formed from oxalic acid, calcium salts and occasionally cysteine. Many such stones are clinically inapparent and asymptomatic. Occasionally a piece of one may break away and either partially or completely block the ureter, the tube carrying urine from the kidney to the bladder. This can lead to severe pain, called renal colic. Sometimes the problem resolves spontaneously and sometimes requires intervention to remove the stones or obstructions.

A gall stone forms in the gall bladder, which is a sack-like bag dangling below the liver and connected to the bile duct. The gallbladder stores bile temporarily before it is released into the small bowel where it aids in the digestion of fats. Stasis of the bile in the gallbladder can encourage the formation of small stones, which are usually deposits of cholesterol, which is highly abundant in bile, and also bile salts. The stones are usually clinically inapparent but can occasionally block the neck of the gallbladder producing pain known as biliary colic. They can also travel down the biliary tree and cause an obstruction which can lead to jaundice and pancreatitis.

So, in summary, two totally different organ systems but with common outcomes when the stones move.

With a mercury level of 14.3ppb to 15.3ppb (urinalysis) what effect could we expect to see on the human body?[:0]

None whatsoever.
OK, it's a bit late to answer this but the mercury levels there are only 2 or 3 times higher than those permitted for drinking water.
"Assuming a 60-kg adult drinking 2 litres of water per day and allocating 10% of the
TDI to drinking-water, since the major sources of exposure are through food, the
guideline value for inorganic mercury is 6 µg/litre. "
From
http://www.who.int/water_sanitation_health/dwq/chemicals/mercuryfinal.pdf

6µg/ litre is 6ppb.
So the real question is why were people saying things like
"i'd be really interested to hear where you were exposed to such high levels of mercury too."
