- Hydronephrosis kidney: the main thing - identifying at an early stage
- As shown
What is hydronephrosis and its causes
Hydronephrosis - a kidney disease in which there is a persistent expansion of the renal pelvis system (cavity in the kidney, which gets urine before its runoff into the ureter), a decrease in volume (atrophy) own kidney tissue (parenchyma) and the growing deterioration of the functions of the kidney due disorders of blood circulation and the flow of urine.
Hydronephrosis develops when there is an obstacle in the way of the flow of urine, which can occur at any site, but most often they are found in the upper part of the ureter, which is adjacent to the pelvis.
Hydronephrosis often develops in the presence of anomalies in the form of an extension of the vessel, which is suitable to the lower pole of the kidney and ureter squeezes directly from its point of origin from the kidney.
Traumatic hydronephrosis can develop because of the compression of the ureter by a blood clot (hematoma) as a result of damage with the subsequent development of adhesions.
Hydronephrosis can be primary and secondary. Primary hydronephrosis develops against the background of congenital anomalies of the renal pelvis, ureter or renal parenchyma. Secondary hydronephrosis is a complication of a disease, such as kidney stones

Tumors, compressing the urinary tract.
Hydronephrosis can also open (for example, open trauma) or closed, infected or aseptic (without infection).
The disease develops due to the fact that urine is retained in the pelvis, compressing the renal parenchyma and disrupting blood flow in it. Gradually, more and more expanded pelvis and kidney tissue is reduced, that eventually cause complete destruction of the parenchyma (the kidney is a bag with the liquid), and renal dysfunction.
How does hydronephrosis
Hydronephrosis occurs gradually over his divided into three stages: initial, early and final. The disease often develops unnoticed and is manifested in the accession of infection, injury or during a random inspection. Symptoms typical for hydronephrosis, no. The most frequent aching pain in the lumbar region of varying severity.
At the beginning of the formation of hydronephrosis patients may disturb the attacks of renal colic

Accompanied by nausea, vomiting, bloating, decreased urine output before the attacks of pain and increased after the attack.
In advanced stages of glomerulonephritis, acute pain usually does not happen. An increase in temperature occurs only when infected and joining pyelonephritis

. Often, hydronephrosis can be felt in the upper quadrant tumor formation. The appearance of blood in the urine

(hematuria) can be a long time the only sign of hydronephrosis.
Hydronephrosis may be complicated by the addition of an infection, the formation of secondary stones (this contributes to stagnation of urine) and rupture of the bag hydronephrotic injury.
Diagnosis of hydronephrosis
Hydronephrosis kidney probed only in the later stages. An important role in the detection of hydronephrosis play radiographic methods. Conducted plain radiography (it is possible to see an increase in kidney and suspect hydronephrosis), excretory urography (contrast material injected into a vein, and after 10 minutes you take a picture where you can see the contours of the extended cups and pelvis). To clarify the diagnosis is sometimes carried out and other X-ray and radioisotope studies of kidneys. Laboratory data also confirm the diagnosis.
Treatment of hydronephrosis
Treatment of hydronephrosis mainly operational. Performed plastic surgery on the ureters, eliminating the causes of hydronephrosis and restore the normal flow of urine that can completely restore kidney function in the early stages of hydronephrosis.
The indication for surgery is the preservation of the kidney tissue and the ability to eliminate the immediate causes of disease. By the removal of the kidney (nephrectomy) resort with such a unilateral hydronephrosis when atrophy (decrease in volume) expressed in renal parenchyma sharp degree and deeply compromised kidney function. Leave a kidney is dangerous because of the possibility of complications. Remove the kidney can not be, if the second kidney also changed.
The main thing with hydronephrosis - is to identify it at an early stage and to establish the reasons why he had been summoned.
