The experience to have a kidney stone was devastating. It was a
very painful experience. I had suffered from kidney stones past 10
years ago during my vacations. I had severe flank pain radiating to
groin with nausea, vomiting, hematuria, fever with chills,
persistant tendency to urinate.
I was hospitalized for couple of days from where I got
discharged against medical advise as the doctors were planning for
surgery.I consulted urologist who did ceratin investigation like
ultrasound, urine analysis. I was diagnosed to have renal stones
which was multiple of small size in both the kidneys.He prescribed
me some medications for 3 months and asked me to drink plenty of
water. He also asked me to avoid tomatoes, green leafy vegetables.
The doctor instructed that one should have adequate fluid intake
inorder to prevent the occurence of kideney stones.
Kidney stone or renal calculi are hard, crystalline
deposits made up of minerals and salt that forms inside the kidney
or urinary tract. Kidney stones are formed when urine becomes
concentrated allowing minerals to crystallize and stick
together. Based on its constitution the renal stones are
of different types:
- Calcium
stones: It is the most common type in which the
stone is formed of calcium oxalate. It may be caused due to
excessive intake of calcium in diet, Increased calcium content of
blood (hypercalcemia) and intake of water rich in calcium. High
oxalate foods are potato chips, peanuts, spinach, beets,
chocolate.
- Uric acid
stones: It is most common in men than women. Mainly
occurs in person with gout or undergoing chemotherapy. It develops
when urine is too acidic. DIet rich in purines increase uric acid
content of the body. Purine is mainly found in animal protein like
fish, shellfish,meat.
- Struvite
stones: mainly found in women with urinary tract
infection. These are large stones which develops due to urinary
infections and may lead to urinary gtract obstruction.
- Cystine
stones: These type of stone are rare. These are
mainly found in people with genetic disorder cystinuria. In this
disorder, cystine which is naturally present in kidneys leaks into
urine.
Risk group and factor
causing renal calculi are:
- Men are more prone to have stones than women.
- Age between 20- 50 years.
- Family history
- Dehydration
- Obesity
- High intake of oxalate and purine diets.
- Hyperparathyriodism
- Gastric bypass Surgery
- Inflammatory bowel disease increases calcium absorption
- Medications like diuretics, antiepileptic,and calcium based
antacids.
Treatment:
The treatment depands on the type of stone. Some common measures
are:
- High intake of water approximately 8-10 glasses of
water a day. In patients having dehydration with nausea
and vomiting, intravenous fluids is prescribed.
- Pain relieve by use of narcotic medications. Other medications
include Allopurinol for uric acid, acetaminophen, diuretics,sodium
bicarbonate, phosphorus solutions, ibuprofen, Naproxen sodium.
- Surgical
interventions:
- Lithotripsy: Its an external
shock wave treatment which breaks the large stone into small
fragments so that they can easily pass from ureter, bladder in
urine.
- Percutaneous Nephrolithotomy:
In this method the stone is removed from a small hole in the back,
mainly done when the stone is too large to pass, pain is
untolerable and when stone results in ostruction.
- Ureteroscopy: This procedure is
mainly done when the stone gets obstruct in ureter or bladder. An
instrument called ureteroscope is introduced into the ureter
through urethra. A small wire with camera is inserted into bladder.
The doctor then uses a small cage to grasp the stone and remove
it.
Prevention:
- Plenty of fluids: The increased
intake of fluid is the main preventive measure. A person should
pass 2.6 quarts of urine per day. Intake of plenty of fluids will
flush the kidneys.
- Diet : Moderate intake of oxalate
foods, salts, animal protein can lower your risk of stone.
- Treatment of underlying diseases like
hyperparathyroidism, cystinuria,obesity
