Most stones are formed in the kidney and some can then travel down the ureter and into the bladder. Occasionally a stone will form in the bladder itself. If the stone is too large it may become lodged in a ureter. Stones in the kidney or ureter can cause blockage of urine flow or irritation to the urinary tract lining.
There are a number of theories surrounding the formation of kidney stones. Some people also appear to have a tendency toward stone formation for different reasons. Once you have formed a stone, there is an increased risk of you forming more stones.
The known predisposing factors for stone formation are:
- Family history of stone formation
- Chronic dehydration
- Decreased mobility levels
- Certain metabolic diseases
- Recurrent or persistent urinary tract infection
Some known causes of stone formation include:
- diseases leading to abnormal crystallisation of urine
- another fragment of stone
- a foreign body e.g. urinary catheter, JJ stent
