Kidney stones can run in families, but there are environmental factors for many patients.
Some causes of stones include:
Dehydration Diet (too much oxalate, too much protein, or rarely too much calcium) Atkins diet Inflammatory bowel disease Gout Urinary tract infections Vitamin C (over 2 grams per day) Calcium supplements if taken without food or if used excessively
Your mother was wrong! It is now known that a LOW CALCIUM DIET will result in MORE STONES for the majority of stone patients. It does not make immediate sense but the majority of patients who make stones DO NOT have a calcium problem. Calcium is most often "just along for the ride." It is not recommended to decrease dairy calcium consumption unless you have had a metabolic evaluation that showed high urinary calcium which decreased on a low calcium diet.
Treatment of Kidney Stones
The role of medicine and diet for kidney stone treatment is mainly for the prevention of future stones or to prevent the growth of existing stones. Prevention will be addressed below.
In rare instances, stones can be dissolved. This is only effective for a smaller, purely uric acid stone and requires frequent medication adjustments and at-home urine testing up to 4 times per day by the patient.
For 90% of stones, there is no proven way to dissolve them or to medically treat a stone that has already formed.
Non-medical treatment options for most patients: non invasive, minimally invasive, and surgical procedures for kidney stone treatment and kidney stone removal.
In general, there are five options available to treat all urinary tract stones. Kidney stone size and location is an important factor in deciding which treatment is best for you.
1. Do nothing: This is best saved for very small stones that could pass easily, or for very large asymptomatic stones in older patients. However, if the stone is causing pain, blockage or infections, it should be treated.
2. Lithotripsy (shock wave lithotripsy, SWL, ESWL):
It is the easiest procedure. The patient lies on a table
or in a tub and shock waves are focused on the stone.
It is non-invasive, but if the stone is over 1 cm, you will
likely need a cystoscopy and stent to help the pieces
pass. Patients can go home the same day.
Lithotripsy is only 60 - 85% effective for making your
kidney or ureter stone free in a single treatment
(depending on stone size and location) . The
recurrence rate is quite high. 42% of patients will
have another stone within two years, probably from
small fragments left behind that grow into new stones.
3. Endoscopic treatment (ureteroscopy, with or without laser stone fragmentation): A urologist can look inside the bladder and all the way up to the kidney with a small scope and either remove the stone or break it up with a laser and remove the pieces. It is minimally invasive. There is no incision as the instruments go through the patient's existing "plumbing." Patients can go home the same day. In experienced hands, the stone free rate is 90-95% for stones in the ureter. The stone free rate is 80-90% for stones in the kidney depending on size and location.

4. Percutaneous removal (also called percutaneous nephrolithotomy, PCNL): Very few urologists are proficient at this technique, which is why many urologists will not offer it as an option for their patients. PCNL is the treatment of choice for stones over 15 - 20 mm (1.5 to 2 cm). Associated Urologists of Orange County routinely uses this technique for patients with large stones or stones refractory to other procedures. While it is minimally invasive, it requires a one inch incision in the back. A channel is made from the skin straight into the kidney. It is invasive, but still considered minimally-invasive. Patients typically spend one night in the hospital (two for older patients). The stone free rate is 90 - 95% for these very large stones that otherwise would require multiple procedures to completely clear.

5. Open surgery: It is extremely rare to need a large incision to remove a stone from the urinary tract.
The choice of treatment will depend on the size and location of the stone. In addition, the more invasive the procedure, the higher the success rate.
Kidney Stone Prevention
Everyone in the emergency room with a stone loudly proclaims "I will do anything to avoid another stone." In reality, very few people will stay on a prophylactic treatment program for many years. Once they feel better, they stop therapy until the next painful stone. The average person who passes a small stone without the need for a procedure (whether it is his first stone or it has been many years since the previous stone) will not benefit much from specific testing and treatment. They are also unlikely to stay on any treatment recommended.
Kidney stone prevention is most important for patients with recurrent stones, multiple stones at one time or patients with very large or difficult to treat stones. Testing includes a 24-hour urine collection, blood testing and chemical analysis of the stone if possible. The possible treatments include diet changes (usually low oxalate diet or decreasing protein), citrate or magnesium supplementation and occasionally medication.
