What Does Renal Cortical Cyst MeanWhat does renal cortical cyst mean? With a high incidence, renal cortical cyst has attracted many people’s attention especially the elderly. However, few of them clearly understand the difference between renal cortical cyst and other types of kidney cysts or whether this cyst is dangerous. Today, we will explain them one by one.

An overview of renal cortical cyst

Our kidney is divided into two parts: renal parenchyma and renal pelvis. All kidney functioning cells are located in the renal parenchyma, which includes renal cortex and renal medulla. This perfect structure makes kidney produce urine, keep electrolyte balance and secrete hormones normally. However, some factors may affect the kidney structure.

Kidney cyst is the most common renal disorder and it can occur at any age, but it is more likely to appear in people over the age of 50. Most of these cysts develop in renal cortex, so we call them renal cortical cysts.

Is renal cortical cyst dangerous?

Most often, symptoms, such as frequent urine, back pain, burning and pain during urination, hematuria, etc, won’t occur unless one of these cysts is larger than 4cm or ruptures. Therefore, we can know small renal cortical cysts are harmless. However, once they are too big or they have caused some symptoms, prompt treatment is very necessary.

How to shrink large renal cortical cyst?

Because these cysts are full of clear fluid, treatments that can remove sacs directly or dry up the sac fluids both are OK. In western medicine, doctor usually recommends surgery for people with large kidney cyst. We must affirm that surgery does have a quick and obvious effect of easing patients’ symptoms, but in the same time, it will damage some kidney functioning tissues. What’s more, removing large kidney cysts will give small cysts more place to grow.

In Chinese medicine, doctor prefers to herbal medicines to prompt the reabsorption of all sac fluid, through improving blood circulation and increasing the permeability of cystic walls. Once these cortical cysts are dried up, the kidney function will be better.
