Kidney Stone and Kidney Stone Surgery
At times a small Calcium Crystal Stone forms inside the part of the Kidney where the Urine is collected. The stones cause pain while urinating. The problem increases when Calcium Crystal Stones falls into the Ureter, a tube that drains the fluid from the Kidneys in to the bladder. There the stones prevent Urine from coming out of the Kidneys and causes severe pain.
Kidney removes waste from the body and filters the Blood to make Urine. The same Urine flows from the kidney into the bladder through the Ureter, a thin tube that connects the two. The Bladder empties through the Urethra, a tube much wider than the Ureter.
Urine from the Kidney excrete a variety of minerals and chemicals, when sometimes these minerals and chemicals combine to form stones. With the passage of time, the stones grow in size, sometimes almost an inch in diameter or even larger.
How are they formed?
The reason isn’t exactly known, but usually changes in the acid-base balance (pH) of the urine and the concentration of minerals and chemicals within the urine are all factors that can signify the formation of a stone. Concentrated urine often occurs during an episode of dehydration, setting the stage for the beginning of stone formation. The consequences of that stone, when it is large enough to cause an obstruction, may occur weeks, months, or years later.
A Kidney stone can infect the Kidney with Pyelonephritis, an inflammation of the renal parenchyma, calyces, and pelvis that is commonly caused by bacterial infection that can spread to the urinary tract or travel through the bloodstream to the kidneys.
When kidney stones pass from the urine collection system into the ureter, they can act like a dam preventing easy flow of urine from the kidney into the bladder. This causes urine to back up, increasing pressure and swelling within the kidney.
Pain in the process
Pain from the Kidney and as the stone passes through the Ureter, the pain increases. Kidney Pain is also known as renal colic Stone can be excruciating and its intensity is similar to that of pain experienced during a child birth. The pain starts from the lower back and radiates to the front of abdomen and in males, it may cause testicular or scrotal pain. It makes the individual totally uncomfortable. Kidney Stone has side effects like Nausea, Vomiting and Sweating.
If not treated the intense pain would be continuous and the pain would considerably increase. Once the stone is in the Bladder, the obstruction is relieved.
Passing of the stone
Since a Urethra is much larger in size than the Ureter, passing of the stone is an easy thing. It passes easily while Urinating and most patients cannot tell when they have eliminated the stone from their bladder.
The severity of the pain does not depend on the size of the stone, but it rather depends on the amount of obstruction and Kidney swelling. Many a times, when Kidney stone passes through the urine’s, a small amount of blood is visible.
