Life Expectancy of Untreated Renal CystIn general, there are three types of renal cyst, including Adult Polycystic Kidney, Simple Renal Cyst and Acquired Renal Cyst. If left untreated, each of the types has a different life expectancy.

Simple Renal Cyst

It is the most common type of renal capsule disease. In most cases, there is one or several cysts in one kidney. The onset usually occurs in adults, having no obvious symptoms and damage on kidney function. At this time, small cyst (<3cm) doesn’t need any treatment, because it is not life-threatening. However, regular urine test is necessary, especially for the elderly, to check whether the cyst is growing.

Does it mean that you do not worry about that at all? No. There is still some chance that the simple cyst becomes dangerous, due to some factors, such as hypertension, hemorrhage and infection. When the cyst grows more than 3cm, certain medicine or a surgery is needed.

Adult Polycystic Kidney

Most of the patients with Polycystic Kidney Disease (PKD) are inherited. Adult polycystic kidney disease progresses into kidney failure slowly. The average of the lifespan of patients with PKD is 50 years, and about 10 years after clinical symptoms appear, and even there are some people who spend their whole lifetime without any symptoms. The life expectancy varies from individual to individual, and influenced by many factors, such as medical history, complications, remaining kidney function, etc.

If left untreated, the following three conditions will happen.

1. Kidney disease

Without timely control, kidney cyst enlarges and presses the surrounding intrinsic renal cells. Kidney function decreases as more and more renal functional cells are necrotic. Furthermore, when kidney cyst enlarges to a certain size (>3cm), especially when it ruptures, it will cause hematuria, proteinuria, abdominal pain or flank pain, hypertension, nausea, breathlessness, unconsciousness, anemia, etc.

However, if enlarged cysts are controlled well or removed, those terrible symptoms will be avoided effectively.

2. Kidney failure

Kidney failure is the worst consequence for the people who have a cyst on the kidney. About half of the polycystic kidney disease patients, more than 50 years old, will get kidney failure. Dialysis and kidney transplant are the conventional treatments for renal failure
