Kidney Cysts - Overview
Basically, Kidney Cysts are the round pouches which are filled with fluid and are formed around the kidneys of an affected person. Most of the times, they are generally associated with the serious disorders which cause the impairment in the basic functions of the kidneys. In most of the cases, the cysts formed are non cancerous and are known as simple kidney cysts.
The basic cause for the occurrence of these cysts is unknown. However, it is know that generally only one cyst occurs on the surface of the kidney. Patients suffering from multiple cysts are known to be affected in both of their kidneys.
Simple Kidney Cysts are the ones that can be easily detected in a person with the help of an imaging test. Some of the cysts are known not to cause any pain or complications and therefore, generally do not require any treatment as well.
Major Signs and Symptoms of Kidney Cysts
Most of the times, Kidney Cysts are not known to show any characteristic signs or symptoms.
However, in some of the rare cases, if the cyst grows out to be of a large size, then some of the major symptoms are as follows:
- Dull and aching pain in the back side
- Consistent fever
- Stabbing pain in the upper abdominal region
It is recommended to see a doctor immediately if one or any of these symptoms appear in a person.
Causal Factors for Kidney Cysts
There is no clear reason or cause for the occurrence of Kidney Cysts. One of the biggest reasons that have come up for the formation of cysts is that they tend to develop on the surface of the kidneys and then gradually form a pouch like structure known as diverticulum. Later on, the pouch fills up with fluid, detaches eventually and forms into a cyst. Often the obstruction of the tubules; the tiny structures which are found in the kidney and are used to collect the urine can also result in the formation of the cysts.
Also, the deficiency of the blood supply to the kidneys too can be one of the major factors for the occurrence of cysts. Research studies are going on to study the influence of the genetic factors too in the development of the kidney cysts. The risks for the development of Kidney Cysts in a person increases as a person ages. Sometimes, due to the occurrence of Cysts in a person, various complications arise such as:
- Infected Cyst: In case the cyst becomes infected, it causes fever and pain in the affected person.
- Burst Cyst: Sometimes, a kidney cyst often bursts, which results in the creation of severe pain on the back side or the other side of a person.
- Obstruction of Urine: Kidney Cysts are often known to obstruct the normal flow of urine which leads to the swelling of the kidney. This condition is also known as hydronephrosis.
Tests and Diagnosis of Kidney Cysts
Some of the best known tests for the diagnosis of kidney cysts are as follows:
- Imaging Tests: The Imaging tests often include the likes of ultrasound tests, Computerized Tomography (CT) Scans, Magnetic Resonance Imaging (MRI) and many other scans. This are often used in order to look for the kidney cysts and therefore, helps the doctor to determine if the kidney cyst is a normal cyst or a cancerous one.
- Kidney Function Tests: These tests are the ones which goes out to test the sample of the blood of the person and thus helps the revelation whether the kidney cyst is impairing the functioning of the body or not.
Treatment and Drugs for Kidney Cysts
In most of the cases, treatment is not necessary for Kidney Cysts. Since Cysts are not known to interfere with the working of the kidney function; treatment is often not needed. Often, doctors come out to recommend the tests for the checking of enlarged Kidney Cysts.
However, if some of the cysts go out to create problems for the patient, then the following treatments are meted out:
- Puncturing of the cyst: This classic treatment is used for the shrinking of the cyst. In this the doctor inserts a large needle through the skin of the person and drains out the fluid from the cyst. Sometimes, the doctors fill the cyst with alcohol solution and therefore prevent the cyst from reforming.
- Surgical Removal of Cysts: In case the cysts are large, then surgery is often needed in order to remove it and drain it. The doctor makes small incisions in the skin along with the special tools. The fluid is drained from the cyst and the walls of the cyst are cut down or burnt completely.
Treatment options tend to vary from one person to the other and therefore, should only be considered after consulting with the doctor.
