What causes kidney stones? – Arash Shadman


The biggest kidney stone on record
weighed more than a kilogram and was 17 centimeters in diameter. The patient didn’t actually
swallow a stone the size of a coconut. Kidney stones form inside the body, but unfortunately, they’re extremely
painful to get out. A kidney stone is a hard mass
of crystals that can form in the kidneys, ureters, bladder, or urethra. Urine contains compounds
that consist of calcium, sodium, potassium, oxalate, uric acid, and phosphate. If the levels of these particles
get too high, or if urine becomes too acidic
or basic, the particles can clump together
and crystallize. Unless the problem is addressed, the crystals will gradually grow
over a few weeks, months, or even years, forming a detectable stone. Calcium oxalate is the most common
type of crystal to form this way, and accounts for about
80% of kidney stones. Less common kidney stones are made
of calcium phosphate, or uric acid. A slightly different type of stone made of the minerals magnesium
ammonium phosphate, or struvite, can be caused by bacterial infection. And even rarer stones can result
from genetic disorders or certain medications. A kidney stone can go undetected
until it starts to move. When a stone travels
through the kidney and into the ureter, its sharp edges scratch
the walls of the urinary tract. Nerve endings embedded in this tissue
transmit excruciating pain signals through the nervous system. And the scratches can send blood flowing
into the urine. This can be accompanied
by symptoms of nausea, vomiting, and a burning sensation while urinating. If a stone gets big enough
to actually block the flow of urine, it can create an infection,
or back flow, and damage the kidneys themselves. But most kidney stones
don’t become this serious, or even require invasive treatment. Masses less than five millimeters
in diameter will usually pass out
of the body on their own. A doctor will often simply recommend
drinking large amounts of water to help speed the process along, and maybe taking some pain killers. If the stone is slightly larger,
medications like alpha blockers can help by relaxing the muscles
in the ureter and making it easier
for the stone to get through. Another medication called
potassium citrate can help dissolve the stones by creating
a less acidic urine. For medium-sized stones up to about
ten millimeters, one option is pulverizing them
with soundwaves. Extracorporeal shock wave lithotripsy
uses high-intensity pulses of focused ultrasonic energy
aimed directly at the stone. The pulses create vibrations inside
the stone itself and small bubbles jostle it. These combined forces crush the stone
into smaller pieces that can pass out of the body more easily. But zapping a stone with sound
doesn’t work as well if it’s simply too big. So sometimes, more invasive
treatments are necessary. A rigid tube called a stent
can be placed in the ureter to expand it. Optical fibers can deliver laser pulses
to break up the stone. Stones can also be surgically removed
through an incision in the patient’s back or groin. What about just avoiding kidney stones
in the first place? For people prone to them, their doctor may recommend
drinking plenty of water, which dilutes the calcium oxalate
and other compounds that eventually build up
into painful stones. Foods like potato chips, spinach, rhubarb, and beets are high in oxalate, so doctors might advise limiting them. Even though calcium
is often found in stones, calcium in foods and beverages
can actually help by binding to oxalate
in the digestive tract before it can be absorbed
and reach the kidneys. If you do end up with a kidney stone,
you’re not alone. Data suggests that rates are rising, but that world record probably
won’t be broken any time soon.

  1. I've had so many kidney stone removal surgeries I probably paid for remodeling the outpatient wing at the hospital. Wonder if there's a plaque with my name in one of the operating rooms?

  2. Just take Chanca Piedra for 6 weeks and drink plenty of water. Also incorporate dry fating periods for a maximum of 3 days a month. This will fix almost everything.

  3. A friend of mine once said to me that she would rather have ten babies delivered through natural birth than passing a single kidney stone. That right there made me realize how terrifyingly excruciating the pain of passing a kidney stone must be. That also made me include the fear of developing a kidney stone on my top-three list of fears.

  4. I've had several of these – worst pain of my life. Fortunately, I haven't had any since my doctor put me on the potassium citrate mentioned here.

  5. Or you could just drink natural coconut water for 1-2 weeks depending on how big the stones are and how much you drink coconut water everyday and the stones will disappear due to the minerals/electrolytes in coconut water and the high amount of Potassium that dissolves kidney stones.
    You could all thank Dr.Sebi for this knowledge.

  6. If anyone is diagnosed with kidney stones then one must drink green coconut water and the coconut inside. It's very simple and effective boil the coconut water and coconut together. And drink it empty stomach every morning and evening. It's very helpful. Let me know what difference you feel after a week.

  7. This is by far the worst pain I ever felt, to date. (Thankful for that) I was cold and sweating, felt like I had to go 1 & 2, I had dry heaves, and I couldn't rest in any position. Once I saw a bit of blood, legit thought I was dying and rushed myself to the ER. The nurses were like, oh.. YoU hAvE A KidNeY StOnE wahahaha. Heres some antibiotics now shut up. Maaaan, I wouldn't wish that on my worst enemy.

  8. Socio-economic and Political changes can improve/break the vicious cycle of malnutrition with specific nutrition and health intervention.

  9. Still not as bad as a kick to the balls, but worse than broken bone, torn ligament, or disconnected muscle. Pain wise: groin kick > kidney stone > broken knee > being hamstringed. I… hardly go out anymore.

  10. no worries for kidney stone……!!…have a bowl of plantain soup regularly for 40 days for better result(ancient tamil medicine)……plantain helps to dissolve the stone completely with no pain…thank me later and like my comment….!!
