Are you experiencing pain in your side or back? Are you noticing traces of blood in your urine? Are you experiencing nausea or vomiting along with the above symptoms? The root cause for all this might be a kidney stone.
Kidney stones are small crystal deposits that are formed from the chemicals present in urine. The growth and deposition of kidney stones might pave the way for the symptoms mentioned above. These stones (also known as Renal Calculi, Nephrolithiasis or Urolithiasis) are of four types: uric acid, calcium oxalate, cystine, and struvite.
But the question is what leads to the formation of these kidney stones. Urine generally consists of several waste materials. When the waste content of the urine goes up and the liquid intake level decreases, kidney stones crystallise. These newly-formed crystals then start attracting other waste elements in the urine, forming a solid mass in the kidney.
This solid mass will stay in the body and grow in size, unless it is passed out via urine or extracted. So, the size of the stone will vary based on the chemical deposition. These stones start at the size of a grain of sand and can grow to the size of a golf ball. Generally, kidney stones are around the size of a chickpea, and there is a chance the patient might just pass it off while urinating.
However, if the size of the stone is considerably large, it calls for a surgery. In case a small stone is detected, patients are advised to keep themselves thoroughy hydrated. Drinking enough water might help the patient get rid of the stone in around 3 to 4 weeks. Passing the stone can be pretty painful, but remember that they usually don't cause permanent damage, given that they are detected on time.
In case there’s a chance of relapse, the health practitioner might recommend preventive methods. Practising them religiously will reduce the risk of recurrent kidney stones.
A person must consult a licensed healthcare practitioner for kidney stones in case he/she experiences any signs or symptoms. To make things easier, here are some kidney stone symptoms one must keep an eye out for.
The position and intensity of the pain caused by a kidney stone might change based on the size of the stone and where in the urinary tract is it present. The location of this pain will keep changing as the stone moves through the urinary tract.
To diagnose a kidney stone, doctors generally begin with a comprehensive medical history, followed by a thorough physical examination and a few necessary lab tests. By doing so, the doctor will determine the kidney stone's exact size and location. This is generally done with the help of a CT scan or an X-ray (KUB X-ray - Kidney Ureter Bladder X-ray).
Post-detection of the stone, the doctor will determine the suitable treatment method. To do so, he/she will first gauge the health of the patient’s kidneys via urine and blood tests.
Once the treatment method is decided and the stone is removed, doctors will try and find the cause behind the formation of the kidney stone. The doctor further analyses the stone once it is removed. The doctor will also check for the level of phosphorous, calcium, and uric acid present in the patient’s blood. A person might also need to submit urine for uric acid and calcium tests.
Here are the diagnostic tests that are used to detect the presence of a kidney stone:
Lab tests for kidney stones are usually carried out using two primary testing samples, blood and urine. Firstly, doctors will ask the patient to take a blood test since it reveals the accurate calcium or uric acid content in the blood.
If uric acid or calcium levels in the blood are higher than normal, then the patient might have a kidney stone.
Furthermore, these blood tests also gauge kidney health, allowing doctors to check for other prevalent health conditions. Secondly, the doctor will also ask the patient to go for a complete urine examination.
A urine test will check for the presence of excessive stone-forming chemicals and elements in the urine. The doctor might ask the patient for two separate urine tests over a two-day window.
Imaging tests can successfully detect the presence and location of the kidney stones. Doctors will either perform a CT scan (dual energy or high-speed computerised tomography) or a simple abdominal X-ray. Both these imaging tests differ in effectiveness.
A simple abdominal X-ray can detect small kidney stones; however, they might miss out on the very tiny ones. On the other hand, a CT scan is a lot more precise and can even detect minute kidney stones for early treatment.
Here are some top treatment options one can adopt to get rid of kidney stones:
If the kidney stone is relatively small, doctors might ask the patient to take care of it at home and eventually pass it out via urine through medications. In this case, frequent and abundant hydration is the key. A medicine dosage will also accompany hydration to dilute the stone further.
Drinking a minimum of 8-10 glasses of water to keep the stones from growing is essential. The key is to have more liquid in urine than chemicals so the existing stone can dissolve and pass.
Other liquids one must consume to get rid of a kidney stone are lemon juice, apple cider vinegar, wheatgrass juice, dandelion root juice and celery juice. Patients must also remember to manage their weight and stay away from caffeinated and sugary drinks.
Kidney stone patients are given medications with the primary goal of managing pain. Also, doctors will prescribe antibiotics to keep them safe from infections. Some other reasons for using medications to tackle kidney stones are as follows:
To achieve this, doctors might prescribe the following medications:
Surgical treatment for kidney stones involves three types of surgery, i.e. ureteroscopy, percutaneous nephrolithotomy, and open stone surgery.
First, let's talk about the ureteroscopy. A tiny instrument (ureteroscope) is inserted in the urethra. It then travels through the bladder and into the ureter. Doctors use this instrument to find kidney stones and retrieve them using a surgical basket. Sometimes doctors also break the stones using a laser head attached to the ureteroscope.
Moving on, a percutaneous nephrolithotomy is employed when no other method of kidney stone removal is working. This can be because the stone is considerably large, or too many in number.
A small incision is made on the patient’s back, through which a tube is inserted directly into his/her kidney. All the stones present in the urinary tract are then disintegrated with the help of an ultrasound probe. These remaining bits are then suctioned out, eliminating the need for the patient to pass the stones out.
Lastly, an open stone surgery essentially involves a larger incission. This is a doctor's last resort and is rarely ever performed.
Another non-surgical method to get rid of kidney stones is lithoscopy. In this case, the patient will be placed on a special surgical tub or table and then sound waves are used to break up the large stones. These smaller pieces of stones can then be passed via urine.
This procedure might get quite uncomfortable and require anaesthesia. Another risk associated with this treatment method is that it might bruise the abdomen, causing bleeding in all the organs surrounding the kidney.
Here are some of the top risks and complications that can happen in case a kidney stone is left untreated.
The passing of a kidney stone doesn’t just happen overnight. In fact, a patient will pass a kidney stone in stages over a period of several weeks. Here are the four stages that entail the passing of a kidney stone:

What is the leading cause of kidney stones?
The leading risk factor for kidney stone formation is the consumption of sodium-, protein-, and sugar-rich diets. An increase in salt levels will consequently increase the calcium supply to the kidneys. This increases the chances of kidney stones formation.
How much time does it take for kidney stones to grow?
Kidney stones aren’t formed overnight. These keep forming as chemicals keep depositing themselves in the kidneys, and this process might even take months. So, if anyone is experiencing mild symptoms, it is advisable to get it checked out.
What size of kidney stone calls for surgery?
Once the size of the kidney stone crosses 0.5 cm, one can have it removed surgically. The stone is too big to pass through the urinary tract safely and might cause bleeding and internal damage to the kidneys and the other organs surrounding it.
