- Kidney Cyst: the need to monitor
- Why is she there?
What is a kidney cyst and why it may be
Renal cyst - a rounded education, and surrounded by a capsule enclosing a liquid (usually it is yellow - the color of urine, but may contain impurities of blood, infected cyst contains pus). Cysts can be congenital or acquired. Recent usually occur after an inflammatory kidney disease or metabolic disorders in the elderly.
The mechanism of formation of cysts is that within his own kidney tissue is blockage of the renal tubules (most often it occurs against proliferation of the epithelium lining the renal tubules inside, resulting in constant irritation in some pathological process), urine accumulates in them, forming a cavity.
Renal cysts may be single or multiple, unilateral or bilateral, congenital and acquired. Their diameter can be up to 10 cm. In most cysts arise in the upper and lower edges (poles) kidney, sometimes - in the middle part of the kidney pelvis area.
What are the symptoms of kidney cyst
The most common kidney cyst is asymptomatic and is found in the random survey. The cyst has an effect only if the blood circulation in the kidney or urinary outflow from it.
When poor circulation in the kidney patient can appear persistent increase in blood pressure and swelling. This should be cause for inspection.
In violation of the outflow of urine, pain in the lumbar region, sometimes permanent, sometimes in the form of attacks of renal colic
Renal colic: a signal that the danger in the bud
. With long-term violation of the outflow of urine own kidney tissue gradually decreases in volume (atrophy), and kidney filled with liquid, losing their functions (hydronephrosis).
Circulatory disorders in the kidney and urine outflow from it can lead to inflammation in it (pyelonephritis), which manifests itself by a sharp rise in temperature and a violation of the general condition of the patient.
Large cysts sometimes (very rarely) may rupture, they can occur hemorrhage.
Diagnosis of renal cyst
Kidney cyst is often similar to kidney cancer. In addition, the cyst is often associated with kidney cancer
Kidney cancer: in the early stages the prognosis is favorable
. Finally, the renal cancer can be cystic structure. Therefore, it is important to quickly identify the cyst and to ensure its purity.
Renal cyst can be identified through a comprehensive survey, which includes ultrasound diagnosis, radiographic methods (panoramic picture of the kidneys and the picture after administration into a vein of a contrast agent - excretory urography), computed tomography (CT), magnetic resonance imaging (MRI). With a thorough examination can reveal a cyst, its size and condition of the kidneys.
Treatment of renal cysts
Small renal cysts do not require treatment - just watch them, eliminating inflammatory kidney disease, impaired circulation, the flow of urine, and cancer. Usually the cyst with a diameter of 5 cm, causing no complications, do not operate.
The indications for surgery are large cysts (the threat of rupture and hemorrhage), violation of the outflow of urine identified in the survey, a strong pain, frequent exacerbation of chronic pyelonephritis, a persistent increase in blood pressure.
Remove a cyst in various ways. A small kidney cyst is most often removed by puncture carried out under the supervision of the ultrasonic beam. From the contents of the cyst is pumped and injected into the cavity of its substance, contributing to bonding cyst wall.
When circulatory disorders of kidney and delay the flow of urine is usually performed abdominal surgery - a cyst carefully separated and removed, and the surgeon is trying not to damage the surrounding tissue. Sometimes (if not expressed violations of the kidney) such operations are carried out endoscopically, using a special optical equipment, introduced through small incisions in the abdomen or back. With this method it is possible to remove the cyst located in any region of the kidney and of any size. In addition, endoscopic equipment (image is seen on the screen) allows the surgeon a good view of the cyst and kidney itself, that is to make the operation less traumatic and safer.
If renal cyst led to the development of pyelonephritis
Pyelonephritis - kidney disease
, It is first treated with medication and then removed cyst. After removal of the cyst or its contents is required to send to the laboratory for analysis to detect abnormal cells characteristic of cancer
