1. That body part has pain sensing nerves.
2. The kidney stone pushes on the nerves.
ESWL is used when a kidney stone is too large to pass on its own, or when a stone becomes stuck in a ureter (a tube which carries urine from the kidney to the bladder) and will not pass.
There are several disorders of the ureter that are congenital (from birth). An example of this is a duplicate ureter, where there is an extra ureter running from a kidney to the bladder. Uterocele is a narrowing of the ureter which could cause urine to back up into the kidneys and damage the kidney. This is usually caused by a small tumor or hernia. A kidney stone might pass into the ureter causing blockage and a lot of pain!
a piece of metal or stainless steel that is put in the tube (in this case, the ureter) to keep it open to help pass the stone. But a stone that large will no doubt not be able to pass thru the ureter. Usually, lithotripsy to bust it up then the stent to pass it later. ouch.
That is correct
No. Kidney stone under 4mm are likely to pass without minor surgery. Anything above that would cause severe pain and would likely need a doctor or urologist to remove. There are many different procedures that can be done. I had a 7mm stone and had to have surgery for removal. I beg to differ here...upto 6mm stones are nto to be touched and they are supposed to come out on their own. Drink lots of fluid and avoid foods causing stones.
Because the urinary tract is designed for removing liquid waste from the body - not solids. Kidney stones are irregular in shape, and often larger than the diameter of he urethra. This irritates the urinary tract, and causes pain when passing the stone(s)
It is not likely that a 9mm kidney stone is going to be passed without assistance.
10 mm
I'm thinking you must be talking about a condition called hydroureter, meaning distention of the ureter with fluid. This is caused by an obstruction of the ureter (the duct between the kidney and the bladder). Several things can cause this obstruction. The most common is kidney stones. These accretions of salts form in the kidney. When the body tries to pass them, they must go through the ureter, which is very narrow, not made for passing solids. So they get stuck, and fluid (urine) builds up behind the obstruction, distending the ureter like a balloon. Once the stone passes and the obstruction is relieved, the ureter returns to normal size. Hydroureter can be dangerous in that excessive back pressure can damage the kidney, which can occur if the obstruction persists.
A kidney stone.
Just really bad pain. It might hurt so bad you have to go to the emergency room. It's very painful.
If they are not bothering you at the time then by all means have a good time, it wont make them any worse.
