Did you know that even with a 20% preservation of kidney function you may quite normally feel? Often it is because of this gradual corruption and a steady decline in functionality of the organ can occur unnoticed for a long time.
So the pain that seemingly spoils the mood and prevents to live normally, in fact it is our “guard dog”, which will force you to pay attention to health. Figuring out the reasons why kidneys hurt, you can learn about the various diseases directly related to this organ or other systemic diseases.
The most common cause why kidneys hurt can be considered an infectious disease. Pathogens come from the bladder or entered the blood and lymph.
Such diseases include pyelonephritis. It is an inflammation of the renal pelvis, which may be caused by bacteria, viruses, and other microorganisms. It contributes to the development of all the States, which hindered the normal flow of urine – the innate features of the structure of the urinary system, kidney stones, prostatic hyperplasia.
Pyelonephritis is characterized by inflammation and abscesses in the parenchyma, which leads to pain in kidneys, General malaise and
Pyelonephritis can often proceed smoothly and for a long time did not find. The pain starts to manifest when purulent-inflammatory process captures almost the entire parenchyma. It is infiltrated with leukocytes and clusters of small pustules, which may merge into large education. The parenchyma is greatly increased, stretching of the capsule causes a constant dull pulling pain. The pain is from the kidneys, which is a localized infectious process, on the right, left or on both sides of the spine.
The pathogen often enters the kidney from the bladder. Therefore, patients with cystitis there are similar unpleasant sensations in the lumbar region and lower back.
Causes of pain in the kidneys can be due to the violation of the structure of the organ. So, in patients with urolithiasis solid formations of “stones” with a long stay in the cups and pelvis cause compression of nerve endings in the lining mucosa. The process is similar to the formation of bedsores on the skin when the body is stationary. This causes tissue ischemia and possible ulceration. Pain occurs when damage to the internal structures of the kidney sharp ridges oxalate stones. They look like a cluster of thin plates with cutting edges.
A special kind of pain in the presence of stones is called “renal colic” and is expressed in a sharp spasmodic pain. She rolls cramping when the stone gets stuck, and the body tries to promote education by rhythmic contractions of the ureter. Characteristic is the intensity of the pain at night or early morning – at a time when people would urinate and the lumen of the ureter is more compressed. The same characteristic symptom, such as pain, and nausea, because there is no outflow of urine and the body is poisoned by excess ammonia.
Hydronephrosis – abnormal enlargement of the cups and pelvis due to the inability of the outflow of urine. This may be caused by the presence of a stone, and spasm of the ureter, adenoma, neoplastic process, proliferation of colonies of fungus in the lumen of the canaliculus, abscess in the abdominal cavity, pregnancy, etc. You feel sick, when the inner complex of the kidney is stretched in the urine. Aching pain is determined in the lumbar region from the affected side. It can also undergo cramping, as renal colic.
In children under one year extension of the pelvis is physiological and should pass on its own, without causing discomfort. But the presence of this condition requires further observation of the child at the nephrologist.
The violation of the morphological structure of the parenchyma
To changes in the functional tissue (parenchyma) can be attributed to a nodule – benign and malignant, as well as polycystic.
In benign tumors the pain is felt in the initial stages, as soon as they started to form because of education compress the nerve endings in the parenchyma. There are feeling a constant dull pain of indeterminate location in the lumbar region.
Kidney cancer metastasizes to nearby tissues, causing pain
Malignant tumors are able to grow through the renal capsule. Pain caused by metastases, which affects nerve fibers, blood vessels, and nearby organs. Also in the destruction of tumor tissue of the kidney is bleeding, and blood clots through the ureter such as stones. It causes spasmodic pain in urolithiasis. The main character of sensations is diffuse pain in the lower back and abdomen of uncertain location.
Polycystic disease is another cause of pain in the kidneys. The parenchyma is replaced by multiple cysts of the bubbles with the inside contents. Because the body in this state is greatly increased, then it begins to push the surrounding tissue. So, lumbar pain in polycystic kidney disease increases in movement and changing body position. Power of feelings may depend on the extent of the process.
A similar condition develops when tuberculosis of the kidney. In the fabric body formed cavity – cavity containing the molten necrotic tissue.
The most important kind of pathology called fusion horseshoe kidneys. The bodies thus combined into one, but each has his own vessels and ureters.
Reasons why kidneys hurt, lie in the fact that the isthmus perelavlivaet nerve endings and supply vessels. So, pain increases with flexion-extension of the body, physical exertion. The ever-present feeling of discomfort in the lower back and abdomen.
Horseshoe kidney presses the blood vessels and nerve endings to the spine, it causes pain syndrome
Basically, this pathology is not operated, but is supportive and symptomatic treatment.
But there are some cases that require surgery:
- the strongest acute pain;
- gidroenergeticheskiy changes;
- the formation of stones;
- the tumor process.
Surgical intervention is the dissection of the isthmus, division of kidney and fixing their new position or the removal of the more heavily affected parts of the body.
Affection of the blood system of the kidney
Atherosclerosis of the arteries is a narrowing of blood vessels that feed the kidneys. This happens when deposition in the wall of the arteries atheromatous plaques. Over time, plaque is the process of hardening – replacement for connective tissue and calcining the deposition of calcium salts. The vessel loses its elasticity, becomes brittle, and its lumen is no longer able to pass enough blood to the kidneys. As a result, starts to atrophy of the parenchyma, it is the process of necrotic disintegration, and this is the reason why kidneys hurt humans.
The most commonly the renal artery affected in their mouth, more on the right. Starting with the II stage of the disease, before the point of blockage is going to a large volume of blood, which causes severe pain in the lower back and abdomen. When a constant injection blood pressure blood vessels can not withstand, and breakthrough occurs, which is accompanied by sharp pain and a sharp deterioration of the General condition of the patient. Often such cases are lethal.
Thrombosis of the renal vein is not an independent disease but a consequence of certain pathological conditions. For example, nephrotic syndrome, crush kidney tumor pathology krovosnabjaemah system, diabetic nephropathy, and even severe dehydration. Acute thrombosis causes a sharp pain in the lower back and abdomen. Because at the same time in the urine of blood appears, it is necessary to differentiate this condition from an attack of renal colic, rupture of cysts. Chronic thrombosis develops gradually and is characterized by dull pain in the lower back.
The undeniable cause of pain in the kidney is its mechanical failure – injury from a blow, crush, fall from height. In this case, violation of the integrity of the parenchyma, rupture of the capsule body, its internal structures, nerve damage – all of which hurt the kidneys. State supported increasing the swelling of tissues, development of inflammation at the injury site and formation of multiple hemorrhages in the parenchyma. If the injury of the renal capsule remains intact, the growing on extensive subcapsular hematoma that also causes a pronounced pain, which gives to the groin.
Kidney injury: grade I – contusion and hematoma; II –surface damage of parenchymal hematoma; III – tissue damage by 1 cm in depth; IV – damage to Cup the renal pelvis complex or acute thrombosis
Paradoxically, causes, kidney pain can be a diagnostic and treatment activities.
Thus, discomfort due to:
- careless introduction of the catheter in the pelvis;
- procedures for the destruction of stones;
- getting a needle in the kidney when performing paranephral blockade;
- percutaneous installation of nephrostomy tube into the kidney for drainage of its internal structures.
There are some conditions in which it can not do without surgery nephrectomy – kidney removal.
To them can be bypassed very:
- launched by the tumor process;
- anomaly body;
- polycystic disease and other pathologies affecting the functionality of the body;
- permanent kamnevidnye;
- traumatic crushing injury.
After removing one of the pair of second bodies for some time fully assumes its function through processes of hypertrophy and hyperplasia of the parenchyma. It can be said, causes pain in kidney, as the remaining organ enlarges in size, and stretches the capsule and feels the pressure of the surrounding tissue.
Other types of surgical intervention on the kidney cause pain due to damage to the integrity of the authority. These feelings pass with time during the recovery period.
But in some cases the pain after the operation indicates the development of complications, such as:
- of infectious complications;
- streaks of urine;
- the divergence of seams.
Dietary habits and alcohol
Alcohol, as we know, substance quite toxic. Ethyl alcohol in the process of filtering the kidney damages the cells lining the blood vessels of the glomeruli. In addition, alcohol has a diuretic effect that causes the urinary system to operate in emergency mode. Together these factors may feel sick in the kidneys. But it happens already at a fairly advanced stage, since these bodies good compensatory abilities. So true – “Late to drink Borzhomi when kidneys have fallen off”. The constant use of alcohol may develop renal failure, nephrosis and other diseases characterized by pain.
Diet, basically, plays a role in the formation of kidney stones. Food rich in oxalic acid, with excess of salt, calcium, phosphorus, protein foods can trigger the formation of stones. In addition, various spicy seasonings, pepper, mustard, sodas, strong coffee can also irritate the kidneys, causing discomfort, and increased urination.
Thus, the reasons for which can hurt the kidneys, a great multitude, and the main task is to correctly determine, as evidenced by your pain.
