Echinococcus kidney

This allocation Echinococcus is 3-5% of all if Echinococcus defeats of man. Occurs mainly in people in contact with dogs, sheep or cattle, more often in men. Affected usually only one kidney, often left.
Echinococcus eggs are with water or raw vegetables in the human digestive tract, where the egg is dissolved and oncospheres their hooks are implemented in Vienna intestinal wall, where fall into the system of portal vein and often end up in the liver. Separate oncospheres through the vessels of the liver fall in the right heart, small circle, left heart, where hematogenous route entered into various organs, including the kidney. Usually formed a cyst (rarely two or more of the fibrous capsule or in the cortical layer, most often in the area of one of the poles of the kidneys.
The cyst is surrounded by a fibrous capsule wall which gradually thickens (up to 1 cm) and tightly fused with kidney parenchyma on the place fit for her. Cyst grows slowly, sometimes over a period of 15-20 years, often reaches a size of an adult head. Having reached a considerable size, cyst causes atrophy of the renal parenchyma, but most of the last remains, as a cyst usually grows to the periphery.
The cyst is made of colorless or yellowish liquid containing hooks Echinococcus and child cysts.
If Echinococcus cyst may be open or closed, that is, to associate or not associate with a Cup or renal pelvis.
When the cyst reach large sizes, there is a nagging pain in the lumbar region, often probed increased bumpy kidney. If the cyst is opened in the renal pelvis, child cysts and hooks stuck in the ureter, can cause an attack of renal colic. In an open form easily susceptible to infections appear pus in the urine and dysuria.
In an open form Echinococcus kidneys in the urine of hooks and child cysts diagnosis simple. In closed form diagnosis difficult. Palpation is determined spherical mobile tumor elastic consistence. Kidney function when the cyst is interrupted in small - can remain normal. On programme pelvis and cups crushed or pushed aside, which often gives rise to the erroneous diagnosis of tumors or solitary cysts in the kidneys. Often the diagnosis is established only on the operating table.
In unclear cases, the diagnosis can be confirmed by the positive reaction Casoni.
Operative treatment. When preserved kidney parenchyma shown resection of cysts or opening it with the subsequent processing of the walls of the cavity 1 % formalin solution and podseleniem edges in a skin wound. With extensive parenchymal involvement kidney shown nephrectomy.
