LOST kidney stone from GP to Lab?

That's a vicious looking photo of a stone that you sent with your message so I sympathise with you over the pain that it would have caused.

80% of stones are calcium based but, as yours never arrived at the lab, you can't be sure if yours was calcium. Still, it would not do much harm to check your diet to see if you are over-dosing on calcium in your diet. Do you, for example, take calcium supplement tablets to maintain bone density? Have a think about what you eat and look up on the web whether they are high-calcium products.

You will still need some calcium in your diet though, so moderation is the key, and maybe you will need some expert advice so ask your GP for advice/referral.

I see that part of the advice was to exercise. Exercising might cause you to become dehydrated and this leads to concentrated urine with a higher risk of stones forming. Soldiers in the desert are at a higher risk of kidney stones because they perspire so much fluid. Therefore, exercise should be accompanied by a high intake of fluid.

Drink lots of water is always good advice. This helps to flush out the stone fragments and to prevent over-concentrated urine crystallising into new stones. Your urine should not be dark at all.

I take a little PLJ (pure lemon juice) in my water because lemon juice is said to dissolve calcium. You will come across other recommendations on the web for dissolving kidney stones naturally.

I understand that pain comes when a stone blocks the ureter or moves through it so pain might mean that something is trying to pass. But, if you can't pass water at all, this might become an emergency so don't let up on your GP or A&E.

If you can live with the pain, your GP might prescribe painkillers until what's left finally passes. I found that Diclofenac was very good so ask about getting some of those.

Good luck.

Keep us posted as to how you get on.

Hmm, I'd devote your energies to looking after yourself instead of trying to discover who lost your stone. It could be anyone's fault and all parties will deny it was them. You'll just go round in circles.

There's some information on here about kidney stones that you will find useful -

I notice a sentence "Limit your coffee, tea, and cola to 1 or 2 cups a day. Caffeine may cause you to lose fluid too quickly, and that can make you dehydrated." There are also some other recommendations about good/bad food and drink assess.

Ow!  The idea of lemon juice is presumably that the urine will become acid and eat the [calcium] stone.  However the body is very good about regulating its own ph balances and I very much doubt if such a simple remedy would work. If it did the urologists would tell you to do it!

People are desparate to find "simple" cures for complex conditions.  There was one going round some while ago that taking large quantities of bicarb daily would "cure" cancer by making the blood alkaline! 

As to the sample getting lost it is unfortunate and yes you could make a formal complaint but where would it get you?  As you identify where did it get lost? 

Best wishes for a permanent cure
