What are Kidney Stones
Kidney stones form when minerals and acid salts stick together inside the urinary system and turn into hard units. It is caused due to various factors like insufficient intake of water, imbalance of calcium, etc. It can affect your entire urinary system.
The most common stone-forming chemicals are calcium, oxalate, urate, cystine, xanthine, and phosphate. When these substances are present in the urine in high amounts, it leads to crystal formation which further grows into different sizes of stones in the kidney. The internal acidic environment in the kidney, excess protein intake, and dietary factors also play a part in stone formation.
Kidney stones are mainly of four different kinds. In some cases, surgery is required, in some cases, doctors destroy or eliminate the stone through safe non-invasive procedures.
Types of Kidney stones
These are the four most common types of Kidney Stone.
- Calcium Oxalate Stone - It forms when calcium combines with oxalate in the urine. The main cause behind its creation is excessive consumption of calcium and decreased fluid intake.
- Uric Acid Stone - A natural chemical compound named purines is present in foods like meat and shellfish. When a person ingests a high amount of purines, it leads to the production of monosodium urate, which further causes the formation of kidney stones. A person is prone to this kind of kidney stone if there is a family history of this disorder.
- Struvite Stone - It occurs due to infections in the upper urinary tract, but its formation is uncommon. At the same time, it is difficult to diagnose at an early stage as its symptoms are not apparent initially.
- Cystine Stone - A hereditary disorder called Cystinuria can be a reason behind the formation of this kidney stone. It leads to abnormal excretion of certain proteins called amino acids.
Causes of Kidney Stones
There are multiple causes that lead to formation of kidney stones. It occurs when crystal-forming substances like calcium, oxalate and uric acid are found excessively in one’s urine while the substance that could prevent the formation of the crystals are inadequate
The following are known predisposing factors that lead to formation of kidney stones:
- Insufficient intake of water
- Too much or too little exercises
- Weight loss surgery
- Excessive intake of proteins
- Urinary Infections
- family history of kidney stones
Symptoms of Kidney Stones
Kidney stones can be very small or quite large in size. The larger it is, the more apparent its symptoms will be.
Take a look at these common symptoms-
- Severe lower back pain, especially in the sides below the ribcage.
- Pain radiating from loin to groin
- Intense pain in the abdomen coming in intermittent frequencies similar to waves
- Pain, burning sensation while urinating
- Blood in the urine
- Cloudy, bad-smelling, and change in urine colour
- Nausea and vomiting associated with pain
- Increase the frequency of the urge to urinate
- Fever and chills
The pain caused by kidney stones can be variable depending on their site as the stones move in the urinary system. The severity increases if the stone gets lodged in the ureters as it can block the flow of urine and cause swelling in the kidney.
Diagnosis of Kidney Stones
The diagnosis of Kidney stones starts with an evaluation of previous medical reports, followed by a physical examination and imaging test.
To ascertain the exact size and shape of the stone, the doctor will perform the following tests
- USG scan of abdomen and pelvis, and if indicated,
- high-resolution CT scan of the kidneys and bladder
- X-ray KUB: kidney-ureter-bladder x-ray.
The reports of the above scans help the doctor to decide the treatment protocol as it gives clarity on how severe the patient’s condition is.
The treatment depends on the size, number, and site of the kidney stones.
When the size is small (typically <10mm), the first line of treatment is to try to eliminate the stones without surgery. Hydrotherapy is used in these cases. In case the stone is big, blocking the urine passage, causing infections and severe pain, etc, it is removed through surgery.
Shock-wave lithotripsy is a safer option as it uses sound waves to break the stones into little grains in order to pass them through urine. Another way is ureteroscopy, where an endoscope is inserted through the ureter to bring the stones out or destroy them inside the body. In case of large complications, doctors prefer to eliminate the stone through percutaneous nephrolithotomy/nephrolithotripsy.
