Kidney stones
Kidney stones in the urinary tract (uriner calculus) is the mass
hard like a rock that formed along the urinary tract and
can cause pain, bleeding, blockage of urine flow
or infection.
These stones can form in the kidney (kidney stones) and in the
bladder (bladder stones). This rock formation process
called urolitiasis (litiasis renal nefrolitiasis).
Causes
Stone formation can occur due to urine saturated with
salts that can form stones or urine
lack of inhibiting the formation of a normal stone. Around
80% rock composed of calcium, the remainder contains a variety of materials,
including uric acid, cystine, and minerals struvit. Stone struvit
(a mixture of magnesium, ammonium and phosphate) also called “stone
infection “because this stone is formed only in the urine of
infected. Stone sizes range from who can not be seen
with the naked eye until the size of 2.5 inches or
more. Large stone called “staghorn calculus”. These stones can be
fill almost the entire renal pelvis and renal kalises.
Symptoms
Kidney stones, especially the small size, can not cause
symptoms. The symptoms of kidney stones depends on the location of the stone.
• Stones in the bladder can cause pain in the
lower abdomen.
• Stones that obstruct the ureter, renal pelvis and tubules
renal can cause back pain or renal colic
(great colicky pain).
Renal colic is characterized by severe pain that relapsing-remitting,
usually in the area between the ribs and hip bone, which
spread to the abdomen, pubic area and inner thighs. Symptoms
Another is nausea and vomiting, bloated abdomen, fever,
chills and blood in the urine. Patients may be
frequent urination, especially when the rock through the ureter. Stone can
causing urinary tract infections. If the stones block the flow of
bladder, bacteria will be trapped in the urine collected
above the blockage, so there was an infection. If blockage
This lasted a long time, urine will flow back into the channel in
in the kidney, causing stress that will
inflate kidney (hydronephrosis) and eventually could
kidney damage.
Diagnosis
Stones that do not cause symptoms, may be known
accident on the examination of routine urine analysis (urinalysis).
Stone that causes pain is usually diagnosed based on
symptoms of renal colic, accompanied with the tender in the back
and pain in the groin or pubic area without causing
clear.
Microscopic analysis of urine may reveal blood,
pus or small rock crystal. Usually not necessary
other tests, except if the pain settled more than a few
hours or the diagnosis is not certain.
Additional checks that can help make the diagnosis
is the collection of urine and 24-hour sampling
to assess the blood levels of calcium, cystine, uric acid and materials
others that can lead to stones.
Abdominal x-rays may reveal calcium stones and rocks
struvit. Other tests that may need to do is
urografi intravenous and urografi Retrograde.
Prevention
Drink plenty of fluids will increase spending and
formation of urine that can help remove
few stones; if the stone has been wasted, it is not necessary anymore
done treatment.
Renal colic can be alleviated with pain medication class
narcotics. Stones in the renal pelvis or ureter the top
measuring 1 inch or less often can be solved
by ultrasonic waves (extracorporeal shock wave Lithotripsy,
ESWL). Stone fragments will then be discarded in the urine.
Sometimes a stone removed through a small incision in the skin,
followed by ultrasonic treatment. A small stone in the ureter
the bottom could be appointed to the endoscope is inserted
through the urethra and into the bladder. Uric acid stones
sometimes will dissolve gradually in the atmosphere urine
base (eg by giving potassium citrate), but the stone
others can not overcome in this way. Uric acid stones
larger, which causes blockage, should be appointed
surgically. Stone formation precautions
depending on the composition of the rocks found in the patient.
Stone is analyzed and measured the levels of material
can lead to stones in the urine.
