How do kidney stones form?Back to top
At the same time, your urine may lack substances that prevent crystals from sticking together. So, the body compensates by forming stones with the excess substances6.
How are kidney stones treated?Back to top
The main goal is to prevent the onset and recurrence of kidney stones.
Drink adequate water daily, to make your urine pale yellow or almost colourless and to achieve urinary output of at least 2.5ml/day4
- Adjust your diet to limit intake of high-risk foods
- Avoid crash, extreme weight-loss diets
- Moderate your alcohol intake
- Check your family medical history
- Have regular medical check-ups
- Take steps to control underlying medical conditions
- Consult your healthcare provider, to get professional medical advice
While the urine is generally darker in the morning, if it’s consistently orange or brown, drink more water until it becomes light yellow or pale straw yellow. You can also check urine pH levels with pH test strips from your local pharmacy.
Pharmacological interventionBack to top
The treatment for kidney stones is similar in children and adults. Doctors may try to facilitate stone passage without surgery. In addition to lifestyle or dietary changes, you may get medication to
- Help pass your kidney stone (diuretic, alpha-blocker)
- Reduce renal colic episodes (non-steroid anti-inflammatory drugs)
- Make your urine less acidic (urinary-alkalinizer)
- Supportive care may also be provided with rehydration therapy, pain relievers, or antiemetics (nausea, vomiting)
Surgical proceduresBack to top
If all fails, surgical procedures may be considered to either break up, remove or bypass kidney stones that are
- too large, or block urinary flow
- delicately located and posing a risk of bleeding, kidney damage
- a sign of recurrent kidney stones and ongoing urinary tract infections
Causes and risk factorsBack to top
A kidney stone often has no definite, single cause, but its prevalence is on the rise. The increase has been attributed to several factors:
- Insufficient water intake
- Dietary choices e.g. high-protein, high sodium (salt), low-fibre intake
- Alcohol intake
- Exercise (too little or too much)
- Family or personal history of stone disease
- Pre-existing medical conditions e.g. dehydration, chronic diarrhoea, obesity, malabsorption, hypertension, diabetes, urinary tract infections
- Habitual use of certain medications e.g. antacids, laxatives
- Trauma or surgery e.g. gastric bypass surgery
Men have double the risk of developing a kidney stone than women 2,3
Signs and symptoms of kidney stones1,2Back to top
The symptoms could be one or more of the following:
- Severe pain (also known as renal colic) on either side of your lower back, which may be accompanied by high temperature
- Frequent urination and persistent urge to urinate
- Blood in the urine
- Urine that smells bad or looks cloudy
Once kidney stones are removed, without preventative measures you have a 50% chance of developing new stones within 5 years or so.5 The average rate of new stone formation in those who develop recurrent stones is 1 every 2 to 3 years.6
