Renal cysts

Renal cysts are often diagnosed last few decades, since the ultrasound came into widespread use. This means that they usually do not cause any problems, but they represent an incidental finding on ultrasound examination of abdominal organs. This is a "bubble" of different size and number, which are filled with clear liquid. They can only be found in one or both kidneys, and by position can be located on the periphery of the kidney (cortical) or central (peripijeličke cysts). The latter knows its growth push blood vessels and nerves of the kidney, which usually results in dull pain. 

Rare tumors are described within the cyst wall. The etiology of the cyst is not completely known, but is thought to be an error in connecting tubule, ie. canals that permeate the kidney. The gradual increase in the absence of any symptoms usually requires only periodic monitoring by ultrasound. If the cysts are very large (7-10 cm or more) and cause a dull pain, it is possible to try a relatively simple percutaneous puncture and sclerosing cysts. It is a procedure that is usually performed under local anesthesia. Under ultrasound is a special needle stabs and evacuate the cyst contents. Then the injected agent whose task sclerosing wall and prevent the re-accumulation of fluid. The procedure is simple, but, unfortunately, often fail, because there is a re-accumulation. If it is peripijeličkim cysts, such procedures are not performed, as this may cause unwanted damage to the large blood vessels in the kidneys. In these, as in the case of sclerosing unsuccessful, whichever is open surgery. A particular problem is finding a large number of cysts of various sizes, which leads to gradual kidney failure, and after years of suffering can end up on chronic hemodialysis (artificial kidney) or kidney transplantation.
