Kidney stones

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:

  • Age
  • Sex
  • Family history of stone formation
  • Chronic dehydration
  • Decreased mobility levels
  • Certain metabolic diseases
  • Occupation
  • Diet
  • 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
