Why Kidney Cyst is Easy to Relapse


I had a renal cyst on my left kidney aspirated it was 6.9cm and then it came back to a 5cmm and again aspirated with alcohol and now it came back to be 2cmm and can you tell me the reason why is will relapse so easily?
There are two types of kidney cysts. More common type of kidney cysts is simple cysts. These are small and thin walled sac filled with fluid. Simple kidney cysts are usually not cancerous. Simple cysts don't harm and need no treatments if there is no obvious symptom. But larger size cysts can cause pain on back, belly or sides, fever, blood in urine and increased urination. These can be treated by urologist easily.
The other type of kidney cyst is called complex cysts. These are said complex cyst because of their irregular and complex structures. These can be non cancerous and may develop to cancer. Only those complex cysts which have many thick walls with septations can develop in to cancer.
Sometimes, kidney cysts are inherited and can cause problems like blood in urine, increased urination, pain on back, belly or sides, repeated kidney infections and high blood pressure. Inherited kidney cysts are called polycystic kidney disease. These cysts can cause problems in other parts like brain, liver, intestines, pancreas, ovaries and spleen.
What are the traditional therapies for kidney cysts?
The use of antibiotics
If the patient complains of fever, pain in the back, abdominal pain or blood in the urine, the doctor may recommend antibiotics to treat the infected cyst. Antibiotic medications work by killing bacteria, which allows the body to heal and overcome the infection. As with most antibiotic medicines, the patient must complete the full treatment cycle to overcome the infection.
Surgical removal of the cysts
One option for removing a symptomatic cyst consists of puncturing the cyst and instilling alcohol inside the cyst to shrink it. This procedure is performed with local anesthesia and involves inserting a needle through the skin and into the wall of the kidney to the cyst site. The physician withdraws the fluid in the cyst and fills the empty cyst with alcohol. However the recurrent rate is quite high.
If the cyst appears difficult to remove, another option for treatment utilizes surgery for removal of the kidney cyst. The physician uses a laparoscopic procedure that requires several small incisions through which a video monitor and tools are placed in the area of the cyst. He then uses the tools to drain the fluid from the cyst. Next, the physician cuts out or burns away the walls of the cyst. It has the advantages of few injuries, quick recover and short hospitalization.
Traditional treatments for kidney cysts are mainly surgery which can help drain the cysts or remove the cysts in a short time. However these therapies only aim at removing the necrotic parts without solving the root problem---the continuous secretion of cystic fluid by the cystic epithelial cells and that is why the cysts are so easy to relapse. When the large cysts are removed by surgery, it will provide more space for the small ones to grow large.
