Urinary stones
Urinary stones (urolithiasis) are small, hard mineral deposits that form inside your kidneys. They have many causes and can affect any part of your urinary tract - from your kidneys to your bladder. Passage of urinary stones can be very painful.
Urinary Stones Symptoms
Urinary stones may not cause symptoms until it moves around within your kidney or passes into your ureter - the tube that joins your kidneys and bladder. Symptoms may include severe pain in the side and back that may spread to lower abdomen, pain on urination (dysuria), blood in the urine (haematuria), foul smelling or cloudy urine, urgency or frequency to urinate, fever and chills.
Urinary Stones Tests and diagnosis
You may have diagnostic tests and procedures, such as blood and urine tests as well as imaging tests. Blood tests may reveal too much calcium or uric acid in your blood. Blood test results help monitor the health of your kidneys and other medical conditions. Urine tests help to ascertain presence of complications such as urinary tract infection or risk factors for repeat stone formation. Imaging tests may show kidney stones in your urinary tract. This may include x-rays, ultrasound, CT or MRI scans of your urinary tract.
Urinary Stones Tests and diagnosis
Small stones with minimal symptoms
Most kidney stones won't require invasive treatment. You may be able to pass a small stone by drinking more water, using pain medications and medication to help pass the stones.
Drinking as much as 2-3 litres a day may help flush out your urinary system. Unless your doctor tells you otherwise, drink enough fluid - mostly water - to produce clear or nearly clear urine. Passing a small stone can cause some discomfort. To relieve mild pain, your doctor may recommend pain relievers. Medications may be prescribed to help pass your kidney stone by relaxing the muscles in your ureter, helping you pass the kidney stone more quickly and with less pain.
Large stones and those that cause symptoms
Kidney stones that can't be treated with conservative measures - either because they're too large to pass on their own or because they cause bleeding, kidney damage or ongoing urinary tract infections - may require more invasive treatment.
To remove a smaller stone in your ureter, a thin lighted scope (ureteroscope) is inserted through your urethra and bladder to your ureter. There are no wounds on the abdomen. Once the stone is located, a laser beam will break it into smaller fragments. A small tube (stent) is inserted in the ureter to relieve swelling and promote healing.
This is the most common endoscopic procedure performed by us with rapid relief of symptoms.
To remove a stone inside your kidney, a ultra-thin lighted flexible scope (ureteroscope) is inserted through your urethra, ureter and up into your kidney through a special access sheath. The special scope is able to bend 270 degrees allowing it to manoeuvre tight curvatures in the kidney to access difficult stones. There are no wounds on the abdomen. Once the stone is located, it can be retrieved with a small stone basket. If the stone is large, a laser beam will break it into small fragments. A small tube (stent) is inserted in the ureter to relieve swelling and promote healing.
Extracorporeal shock wave lithotripsy (ESWL) uses sound waves to create strong vibrations (shock waves) that break the stones into tiny pieces that can be passed in your urine. This is the most common non-invasive procedure performed by us.
