Parenchymal kidney disease are described as cysts on the kidneys which are filled with a liquid. For unknown reasons these cysts are appearing inside the kidneys and can have a serious impact on their functions. However, commonly, kidney cysts are called simple kidney cysts – the non-cancer genic cysts that are rarely causing complications. It is not yet known what causes these simple kidney cysts. It is typical that only one cyst appears on the surface of the kidneys, but it can occur that one cyst affects one or both kidneys. Parenchymal disease on kidneys are commonly discovered during screening, because of doubts on some other condition. Simple cysts on kidneys usually do not cause any symptoms and their presence doesn’t require treatment.
Causes of parenchymal disease
It is yet unclear what causes simple kidney cysts. One theory suggests that kidney cysts develop once the surface layer of the kidneys weakens, creating a little bag. It starts to separate and develops into a full sized cyst.
Symptoms of kidney cysts
Simple cysts on the kidneys usually do not cause any causes or symptoms. In case the cyst becomes big enough, these symptoms may include:
- Numb pain in back or on the side
- Pain in the upper belly
Treatment of kidney cysts
Treatment in most cases isn’t even necessary. If the kidney cysts shows no sign or symptoms and has no ill effect towards functioning of the kidneys, treatment is not an option. Besides that, your doctor might recommend that you do check in every once in a while to get an ultrasound test to see how are the cysts developing. If there are obvious growths in kidney cysts, treatment is required. In most cases, however, the cyst will perish on its own.
If your cyst does show symptoms, there are several options. First and most obvious option is to puncture the cyst and then refill it with alcohol. Rarely, I order to reduce the volume of the cyst, doctor will insert a long thin needle through the skin and through the walls of the kidney cyst. This is how the fluid is being extracted out of it. Usually it gets refilled with an alcohol solution to prevent any further issues, and in most cases cysts do disappear permanently after this process so this is considered to be one of the most effective procedures.
Large or symptomatic cysts may require surgery with the main goal being its removal. In order to reach the cysts the doctor will perform a series of tiny cuts on your skin, through which he will insert special medical instruments as well as a tiny video camera. Surgeon then leads the instruments to the kidneys and uses them to let the fluid out of the cysts. Depending on the type of the procedure, treatment for kidney cysts may require a short period of time to be spent inside the hospital.
