Bladder stones are hard lumps of minerals that can form inside the bladder when it's not completely empty of urine.
They may not cause any symptoms if they're smallenough to be passed out of the bladder when you pee.
However, most people with bladder stones do experience symptoms because the stones either irritate the wall of the bladder or block the flow of urine.
Typical symptoms of bladder stones include:
Most cases of bladder stones affect men aged 50 or older, because ofthe link with prostate enlargement (see below).
It's rare for bladder stones to affect children. In children,they can lead to bedwetting , and some boys may experience priapism a persistent and often painful erection that can last for hours.
See your GP if you experienceany of the above symptoms, particularly if you have persistentabdominal pain, need to pee more frequently, or haveblood in your urine. These symptoms may not necessarily be caused by bladder stones, but need to be investigated further.
If your GP suspects you have a stone in your bladder, you'll be referred to hospital for testing.A blood and a urine test will probably be carried out first. A blood test will detect if there's an infection inside yourbladder.
The next stage is to take an X-ray of your bladder. Not all types of bladder stones show up clearly on X-rays, so a negative X-ray result doesn't always mean that you don't have bladder stones. An ultrasound scan may be used instead of an X-ray.
Bladder stones can also be identified using a cystoscopy . Athin, fibre optic tube with a light and a camera at one end (a cystoscope) is inserted into the urethra (the tube that carries urine out of the body) and moved up into the bladder. The camera relays images to a screen, where they can be seen by the urologist (specialist in treating bladder conditions).
Each year in England an estimated 6,000 people are admitted to hospital to be treated for bladder stones.
Bladder stones usually form when you can't completely emptyyour bladder of urine.
A common reason for this in men is having an enlarged prostate gland that blocks the flow of urine.
If urine sits in the bladder for a long time,chemicals in the urine form crystals, which harden into bladder stones.
The most commonprocedure is acystolitholapaxy, where a thin tube (cystoscope) with a camera at the end is used to find the bladder stones. The cystoscope will then use 'stone-crushing' devices, lasers or ultrasound to break up the stones before they're removed.
Where possible, it's important to treat the underlying causes of bladder stones to prevent new stones developing in the future.

Read about the possible causes of bladder stones, which develop when a person is unable to completely empty their bladder of urine. In men, an enlarged prostate can sometimes be to blame.
Find out how bladder stones are treated. In most cases, surgery is needed to remove them. A procedure known as transurethral cystolitholapaxy is usually used in adults.
