What are the Causes of Kidney and Ureteral Stones?

Kidney stones form when the concentration of kidney-forming molecules in urine is too high.  The most common cause of kidney stones is dehydration as often happens in the summer.  High levels of uric acid and calcium in the urine also predispose to kidney stone formation. Some patients have genetic predisposition to kidney stones, other patients have diets that predispose to kidney stones.

What is the Cause of Kidney Stone Pain?

Kidney Stone PainWhen kidney stones start to migrate through the ureter into the urinary bladder, they may cause partial or complete blockage of urine flow from the kidney.  Increased pressure in the kidney cause pain.   Stones themselves typically do  not cause pain unless they cause blockage to urine flow.  Most stones in the kidney do not cause any symptoms unless they obstruct urine flow.

Treatment Options for Kidney Stones

For patients who have acute pain from an obstructing kidney stone, a ureteral stent may need to be placed to relieve the obstruction and to treat the pain.  We evaluate each patient individually. Depending on the situation, some patients may be able to avoid ureteral stent and have one of the treatments for kidney stones such as ESWL lithotripsy.

For patients who require surgical treatment of kidney stones, we offer the following treatments:

Treatment of kidney and ureteral stones in patients with heart disease who take aspirin and other blood thinners.

These procedures can be performed in the ambulatory surgery center or hospital settings.

Kidney Stones: Prevention is the New Treatment

Believing that there is a better way to care for men and women with kidney stones, the first comprehensive Kidney Stone Clinic in New York City was born at New York Urology Specialists.  Dr. Shteynshlyuger coupled a humanistic approach with  the best available science on prevention and treatment of kidney stones to offer outstanding medical and surgical care for men and women suffering from kidney stones.

Dr. Alex Shteynshlyuger is an accomplished surgeon who is fellowship trained in minimally invasive treatment options for kidney stones including lithotripsy.    Dr. Alex Shteynshlyuger opened the first comprehensive Kidney Stone Clinic in NYC.  Our clinic addresses the previously unaddressed need for a comprehensive approach to keeping patients stone – free, with prevention as a major focus of care.  We have extensive experience caring for patients with complex kidney stone histories. Dr. Alex enjoys the surgical challenges and the medical complexity of evaluating and treating men and women with kidney stones.

When it comes to leadership in innovative kidney stone care, Dr. Alex was among the first urologists advocating non-surgical treatment for small ureteral stones, called medically expulsive therapy.  This approach has become the standard of care nationwide.

Choosing the right treatment requires a thorough understanding of the treatment effectiveness of each treatment modality in different situations.

Using more modern approaches to kidney stone care in combination with the latest research and advanced technologies, we are able to minimize the number of procedures necessary to make patients stone free. We optimize our approaches to minimize risks and maximize success of treatment for each treatment.  Using such parameters as Hounsfield units (HU), stone size and stone location.

What are Kidney Stones and How are They Formed?

Kidney stones or renal calculi are a common problem worldwide with an incidence of 8 to 15% in the USA and Europe. Stones most frequently occur in men and women aged 20 to 40 years, although stones are seen in all age groups. Kidney stones occur more frequently with increasing age and there is a male to female ratio of 3:2.  Among patients who experienced one episode of kidney stones, the disease usually recurs in more than 50% of patients within 10 years. Kidney stones are associated with chronic kidney disease, bone disease,  type 2 diabetes mellitus, and the metabolic syndrome.

Kidney stones develop when mineral crystals precipitate out from the urine and aggregate within the kidney. Kidney stones usually leave the body by passing with the urine stream. Many small stones are formed and passed without causing any symptoms.  If stones grow to sufficient size (usually at least 3 mm) they can obstruct the ureter. Kidney stones >5 mm in diameter are at higher risk of getting stuck in the ureter.

  • Calcium stones: The vast majority of kidney stones are calcium stones, either calcium oxalate or calcium phosphate. High concentrations of calcium and oxalate in the urine lead to stone formation. Oxalate is a natural substance found in foods such as nuts, chocolates, fruits, and vegetables. A calcium-rich diet or high doses of vitamin D can increase the concentration of calcium in the urine.
  • Struvite stones: These stones are formed in response to an infection in the urinary tract. They have a tendency to grow rather quickly, often without warning or associated symptoms.
  • Uric acid stones: These stones form in people who have highly concentrated urine. This can be from either not drinking enough fluid or losing too much fluid. Eating a high-protein diet is a risk factor for uric acid stones. People who have gout (a type of inflammatory arthritis) are more likely to form this type of kidney stone.
  • Cystine stones: People with a genetic condition called cystinuria excrete too much cystine (an amino acid) in their urine and have a tendency to form cystine stones.

Urologists at New York Urology Specialists are among the ranks of elite urologists in NYC that provide care for kidney stones.
