Definition and causes
A cyst is a fluid-filled bladder in a body. It is well-defined and does not grow into the surrounding tissue, which makes the cancer nodules. A cyst is not dangerous in itself, unless it reaches a size where it hit the important structures. In some cases, a cyst, however, have arisen as a result of cancer in the body.
Nyrecyster can be divided into three types:
- Simple cystsis the most common form. It is simple show cysts, which occur in normal kidneys and is quite harmless. If they are discovered, it usually happens by chance in the investigation of other illness. The cause is unknown, but some. half of all 40 year olds have one or more simple nyrecyster.
- Policy inherited genetic diseasesdenotes a handful of hereditary disorders that generate numerous cysts in both kidneys. One type is congenital (infantile polycystic kidney disease), Another is showing symptoms in adults (adult polycystic kidney disease) In 40-60-years of age. The latter is the most common (although rare) with 1-2 cases per 1000 population members.
- Cysts of kidney failure and other diseases. In the longer term, chronic renal failure and dialysis treatment eroding the kidneys, and formed gradually cysts in the kidney tissue. Nyrecyster can also occur in a few more rare disorders, and may be associated with kidney cancer.
Symptoms of cysts in the kidneys
As mentioned, simple nyrecyster few or no symptoms. They may, however, a rare time in between being the seat of infection or cause slight bleeding, as seen in the urine. When they reach a certain size, or becomes infected, they can give pain or printed on the side of the kidney.
In polycystic kidney disease formed so many cysts that the functioning kidney tissues ousted. This may cause dysfunction, which may prove to needs for nocturnal urination and possible. pain of the kidney. There may develop high blood pressure, and polycystic kidney disease may eventually lead to kidney failure. Symptoms of this typically begins in 40 to 60 years of age. There can be developed cysts in other organs, especially the liver, and the first symptoms can come from here. In addition, you may cause aneuri
As mentioned, the cysts in some cases have occurred because of a kidney cancer, see signs of this.
Precautions and diagnosis of cysts in the kidneys
Do we have the blood in the urine and / or print, pain or heaviness sensation in the side, you should consult a doctor. It is important to have provided the cause of the symptoms because they do not differ greatly from the symptoms of kidney cancer. Do we have the adult polycystic kidney disease in the family, should undergo ultrasound examination of the kidneys occasionally in order to detect any. disease early.
Cysts occurred after prolonged dialysis should also be examined as these may develop into malignant tumors (cancer nodules).
Diagnostic may be a cyst separated from a tumor, since it is liquid-filled, where a tumor is more massive and contains blood vessels. This can be seen with different imaging techniques. Hosp. it may be necessary to take a sample of fluid from the cyst with a hollow needle.
Treatment of cysts in the kidneys
Simple nyrecyster usually require no treatment. If the cyst has been so great that it gives print, pain or bleeding, you can enter between jettison its contents with a thin needle of a syringe.
Treatment of polycystic kidney disease consists primarily of detailed blood pressure treatment, diet and when it becomes necessary because of increasing kidney failure, dialysis treatment and / or kidney transplantation. Polycystic kidney disease can not be cured, but the early start-up of treatment can slow down its development, thereby delaying kidney failure.
Do we have the great genes from nyrecyster, or discover the cancer in them, will often choose to remove the kidney through an operation. This presupposes that the other kidney is functioning, but in this case one can live a perfectly normal life with only one kidney.
