Kidney stones

What are the kidneys?
The kidneys are two bean-shaped organs located on either side of the spine, just below the ribs. They are part of the urinary system.
The kidneys filter the blood to remove waste and excess salts, minerals, and water, forming urine.
The urine made by the kidneys drains to the bladder through two long, narrow tubes called ureters.
What are kidney stones?
Kidney stones are rock-like crystals which form in the kidneys from the salts and minerals in urine.
Kidney stones form when the concentration of salts and minerals in the urine are too high.
The risk of forming kidney stones increases with dehydration and a diet high in salt, protein, and oxalate. Due to our hot climate, kidney stones are a very common problem in Queensland.

What are the symptoms of kidney stones?
Stones in the kidney usually cause no symptoms. Symptoms can occur when the flow of urine is blocked by a stone which has moved from the kidney into the ureter.

Back pain

Nausea and vomiting

Blood in urine
Painful urination

How are kidney stones diagnosed?
Kidney stones are usually diagnosed by a CT scan of the kidneys.
How are kidney stones treated?
Small kidney stones which are in the kidney and aren’t causing any symptoms often don’t need any treatment. Sometimes they will pass naturally with the aid of pain killers and muscle relaxant medication.
Kidney stones which are large or painful may need surgery to remove them. Most kidney stone surgery is minimally invasive.
Common options for kidney stone surgery include Ureteroscopy, Extracorporeal Shockwave Lithotripsy (ESWL), and Percutaneous Nephrolithotomy (PCNL).
