Just like in any other organ mucosa-lined, the bladder may be formed polyps. In contrast, polyps from the intestine and gallbladder polyps bladder not often degenerate into malignant tumors, however, a variant of the disease is not excluded.
How and why are formed in the bladder polyps
Polyps in the bladder is usually formed on a background of long inflammation in combination with a hereditary predisposition to the disease. Genetic predisposition – is particularly family structure and metabolism in the field. So if someone in the family has found polyps, his relatives are at risk for the disease.
Polyp in the bladder can be formed in the long course of chronic cystitis – inflammation of the bladder. In this case, during remission occurs proliferation of the mucosa. And since the state of the mucous membrane inflammation broken, restoring mucosal sites are. If such a site mucosa has grown too much and it is bulging into the lumen of the bladder, this is called polyps. Polyps may have different sizes (from a few millimeters to several centimeters in diameter) and shape. But in most cases, they are round and sit on a thin stem. Polyps of the bladder can be both single and multiple.
In some cases, referred to as polyps and benign tumors of the bladder. Sometimes the disease is completely transparent and the patient is unaware of his presence. Polyps of the bladder, as well as any other neoplasm, may degenerate into a malignant tumor (malignant), but it is not as common as in the polyps of the gallbladder or gastrointestinal tract, so they are not always removed, sometimes (at small in diameter few millimeters polyps) just watch them grow.
Signs of bladder polyps
A feature of this disease is that it flows seamlessly. But if a polyp is large, it is often prone to failure, and then in the urine may appear blood. Blood in the urine may be quite a bit (in which case it can be found only laboratory method in the study of urine), and can be a lot of urine and then periodically acquires a pink or even red.
Large polyp, located near the ureter or urethra (urethritis) can close their lumen, causing symptoms of acute urinary retention with severe pain and urge to urinate when it is impossible to urinate. The same symptoms can occur when a small polyp on a long stalk.
Polyp can become complicated necrosis (dying off) tissue and bleeding, as well as the constant recurrence of inflammation in the bladder.
Diagnosis of bladder polyps
If you suspect a polyp in the bladder on first ultrasound (U.S.) art. On ultrasound revealed soft-tissue formation in the bladder wall protruding into the lumen.
To clarify the nature of education reins endoscopic examination of the bladder – cystoscopy. In this case, the bladder entered a very small video camera that lets you see on the screen all the details of the changes in the mucosa, including the tumor, determine its size and appearance. Often during cystoscopy is white piece of tissue for analysis (biopsy) to determine the nature of education.
In some instances be carried out also radiographs bladder preliminary introduction into its cavity contrast agents – cystography. In this case, the contrast material fills the cavity of the bladder, and against this background that stands out clearly in the formation of its wall.
Be sure to also conducted laboratory tests of urine (it can be found signs of inflammation and blood) and biopsy material to avoid the degeneration of a polyp to a malignant tumor.
Treatment bladder polyp
Small polyps of the bladder, which does not manifest itself, is often not removed, and just watch them grow. If a polyp grows, tends to close the gaps ureters or urethra, or bleeding, then it is removed.
Polyp removal of the bladder is typically carried out using a cystoscope operating under general anesthesia. In the cystoscope is a very special small surgical instruments to carry out small operations. When you remove the polyp is used diathermocoagulation: polyp is superimposed on the loop is heated to a high temperature and remove a polyp. Such an operation usually occurs bloodless as simultaneously when exposed to high temperature soldered blood vessels.
