A tumor is a knot, ie. a finite liquefaction of tissues, which can be either benign or malignant. Benign tumors can sometimes grow large, if there is space (eg. In the bladder cavity), but they do not grow into the surrounding tissue. Malignant nodules (cancer) can grow invasive into the surrounding structures and may eventually spread to the lymph nodes and with the blood to other organs (metastasis).
Bladder Tumors can be both benign and malignant (approximately equal numbers of each). They are deleted from cells of the bladder lining. It is the same type of cells that seen in other disorders:Kidney basin, Who is sitting with kidney and collect newly formed urine, as it looks down throughUrine leadersto the bladder. When there is a tumor in the bladder, there may also be tumors in these structures.
Bladder Tumors are relatively frequent in some. 1,600 new cases per year in Denmark. It is 3-4 times more frequently in men than in women and may be more common around 60 years of age.
Causes of bladder tumors
It is not possible to identify a single cause of bladder tumors, but we know some factors that greatly increases the risk of tumor development in the urinary tract. These include on certain chemicals, mainly used in color and lakindustrien, but most is smoking, which we believe are responsible for up to half of all bladder tumors. The tropics are the widespread parasitic disease Schistosomiasis the biggest risk factor.
Symptoms of bladder tumors
The most common symptom of bladder tumors and renal pelvis tumors is blood in the urine. It may look like fresh blood or be so little that the urine only slightly discolored or look perfectly normal out. This is often the only symptom, and it need not be there all the time. There may be a long time before you go to the doctor, and the tumor was discovered.
There may also be symptoms resembling cystitis, skin namely small, frequent and sometimes painful urination. Renal Pelvis Tumors can provide print or feeling heaviness in the side, similar to the kidney.
If the tumor is located at a point where it creates a barrier to urine drainage, it can cause infections in the form of blærebetændelse or renal pelvis.
Precautions and diagnosis
Seeing Monday blood in the urine or signs of cystitis, skin should always consult a doctor. The diagnosis made after a series of studies, which typically involves urine examination and blood tests in the first place. Then you can use for example. X-ray or CT scan with contrast of the urinary tract, to see the tumor (see photo studies).
By suspected tumor in the bladder, you will usually also make a kikkertundersøgelse bladder through the urethra (cystoskopi). If you look at cystoskopien a tumor, take a tissue, which examined microscopically, to determine whether the Gordian knot is benign, or whether it is cancer.
Treatment of bladder tumors
About half of all detected bladder tumors are found to be benign. These, as well as tumors that are detected early and has not yet grown into the bladder wall may be burned or cut away by a cystoskop (telescope instrument) through the urethra.
In the case of a cancer that grows into or through the muscle layers of the bladder wall, it must be removed by a large, open (not with the telescope technique) operation. You may need to remove the bladder completely, then to construct a new bladder of a piece of intestine or insert an artificial bladder. Sometimes they will choose to supplement with radiotherapy. Renal Pelvis Tumors treated by removing the kidney and urinary leader in the medical side, but only if the other kidney functioning as it should.
When surgery for bladder or renal pelvis tumor, is a relatively high risk of recurrence can form a tumor (seen by some. Half of the first tumors). It performs control cystoskopi regularly to detect new tumors in the bladder quickly. By frequent superficial tumors, it can help to get washed bladder with a special liquid, which contains weakened tuberculosis bacteria (BCG-washing).
If the cancer has spread to nearby lymph nodes or blood to other organs (typically the liver, lungs and pelvic bones), helps the operation is not. You can then use chemotherapy, which relieves symptoms and prolong the life, but actually cure of bladder cancer with chemotherapy are rare.
Forecasts of tumors in the urinary bladder (and Renal Pelvis Tumors)
When a bladder tumor is superficial and has not spread, ie. it may be operated, the prognosis is good. Are there local indvækst or spread to lymph nodes or other organs, the prognosis is poor and few are cured. By renal pelvic tumors are generally worse prognosis than for bladder tumors and are also here clearly worst, in the spread of the disease.
