Stone Disease

While there is not one definitive reason for the development of kidney stones, many factors contribute to the condition. Risk factors include:

• Caucasian male
• Family history of kidney stones
• History of urinary infections or diseases
• Dehydration
• High-protein diet
• Intake of oxalate-rich foods
• Certain bowel conditions
• Obesity
• Urinary obstructions
• Endocrine disorders
• Calcium disorders

The following are the most common symptoms of kidney stones.

• Sharp, cramping pain in the back, side or lower abdomen
• Pain can come and go
• Blood in the urine
• Nausea and vomiting
• Cloudy or odorous urine
• Frequent urination
• A burning feeling when you urinate
• Fever and chills

In addition to a complete medical history and physical examination, diagnostic procedures for kidney stones may include the following:

• Intravenous pyelogram (IVP), X-rays of the kidney, ureters and bladder with contrast dye injection into a vein to detect abnormalities and assess renal blood flow.
• CT-scan, an imaging study of the kidney, ureters and bladder with contrast dye to find abnormalities or obstructions, and to assess renal blood flow.
• Urinalysis, a laboratory examination of urine for red and white blood cells, infection or excessive protein.
• Blood tests to detect substances that might promote stone formation.
• Renal ultrasound, a picture of the kidney to determine its size and shape and to detect abnormalities or obstruction.

Stone size, the number of stones and their location are important factors in deciding the appropriate treatment for kidney stones. Surgical treatment of stones may include:

• Shock waves or extracorporeal shock wave lithotripsy (ESWL) sends shock waves to the kidney stone to break a large stone into smaller stones that will pass through the urinary system.
• Ureteroscope inserts a long wire with a camera into the urethra and through the bladder to the ureter where the stone is located and removed.
• Tunnel surgery (percutaneous nephrolithotomy) makes a small cut in the back and tunnels through the skin to the kidney where the stone is removed.

According to the National Institute of Diabetes and Kidney Disease (NIDKD), the best way to prevent kidney stones includes the following:

• Drink more water. Up to 6 to 8 eight-ounce glasses of water a day can help flush away substances that form stones.
• Limit caffeine.
• Consult your doctor regarding dietary modifications.
• Medications may prevent calcium and uric acid stones from forming.

You will receive a thorough diagnostic evaluation and receive clinically-proven treatment by a board-certified urologist who specializes in treating kidney stones. Recovery times vary depending upon surgical treatment, with less invasive procedures having shorter recovery times. You will be encouraged to drink extra fluid post-operatively and may need follow-up blood and urine tests.

Brigham and Women’s Faulkner Hospital practices a multidisciplinary approach to patient care, routinely collaborating with colleagues in other medical specialties. If your urologist discovers that an underlying illness has contributed to the kidney stones, you will be referred to an appropriate BWFH or BWH physician for an evaluation.
