Simple renal cysts, don’t be afraid, it’s nothing serious

Why are there renal cysts? ? In fact, the reason is not particularly clear until now, but there are some explanations that can be explained, that is, our kidney has about one million nephrons , which make up the kidney The basic structure, and each nephron is composed of two parts: renal corpuscle and renal tubule . The renal corpuscle is mainly composed of glomerulus And the renal capsule,

we can simply understand the glomerulus as a filter, our blood flows through the kidney, then the glomerulus plays a very important role in filtering It will expel some wastes and impurities. The renal tubule is not just a pipe. It also has a very important reabsorption function . The substance has to be absorbed back into our blood.

But if this renal tubule is blocked, then It is possible to form a cyst slowly , so under normal circumstances, a simple renal cyst often has a thinner cyst, and the inside is filled with fluid. In this case, we It is called simple renal cyst .

In this case, the possibility of malignant transformation of a renal cyst is very small, which can be said to be 0%.

Although there is a simple kidney cyst that does not become malignant , it can sometimes induce some symptoms, such as secondary infection , may cause patients to develop fever , some patients will show pain between the ribs and pelvis , especially the pain on the back and waist side, some As for the patient, it will also show as abdominal pain. If the cyst ruptures, there may be hematuria,

but the possibility of this happening is really not very high , You don’t have to pay much attention . With this kind of simple kidney cyst, we just need to observe regularly. Generally, renal cysts smaller than 4 cm, we don’t need to pay too much attention to it , Regular color Doppler ultrasound inspections are enough to dynamically observe its changes in size.

If the cyst is over 4 cm , and it grows faster after dynamic observation, and the patient has certain symptoms, then you can consider it in For surgical treatment under a laparoscope , the top cover of the cyst is removed to release the cyst fluid.

Then some friends may ask, how can they know if they have such a simple kidney cyst? In fact, most patients with kidney cysts are found during physical examinations, or when they are screened for other diseases. Color Doppler ultrasound and CT examinations can help us confirm the diagnosis.

Seeing here, everyone should have a certain understanding of simple renal sac . Next, let’s talk about it. It may evolve and cause Renal failure, and those renal cysts that may be malignant!

polycystic kidney

polycystic kidney and simple renal cyst are not the same thing A simple renal cyst has relatively little stimulation to the entire kidney. As mentioned earlier, we must pay more attention to it after more than 4 cm.

Remedies For Renal Cyst Efficient?

but Polycystic kidneys are different. You can imagine that there are a dozen or even dozens of cysts of different sizes in a kidney. These cysts will severely squeeze the function of the kidneys and induce Patients have many serious problems such ashigh blood pressure, low back pain, urinary tract infections, and kidney stones. Some patients may develop abnormal renal function after 30 to 40 years old, which may eventually lead to kidney Functional failure, andpolycystic kidney disease is also the fourth leading cause of kidney failure.

What is the cause of kidney cysts? Will it become malignant?This type of polycystic kidney disease is a genetic disease, and dominant polycystic kidney disease is more common in adults , also known as adult Cystic nephropathy , men and women have the same chance of getting the disease, and recessive functional kidney, also known as childhood polycystic nephropathy, is a rare genetic disease.

In the early stage, polycystic kidney disease has no special symptoms, because the cysts are relatively small and the compensatory capacity of the kidneys is particularly large , but as time goes by, many Patients may experience symptoms such as abdominal pain, frequent urination, back pain on both sides, easily injured skin, skin may become pale, and frequent fatigue.

For the diagnosis of polycystic disease, CT and color Doppler ultrasound are usually the main force. If your parents have polycystic kidney disease, you should pay more attention to your kidneys. If you are healthy, you must undergo a physical examination every year.

Other types of renal cysts, you need to understand!

This is a very important Bosnian renal cyst grading system. Dr. Xie, today I will give you a simple science popularization, and you will understand after reading it.

Why are there renal cysts? ? In fact, the reason is not particularly clear until now, but there are some explanations that can be explained, that is, our kidney has about one million nephrons , which make up the kidney The basic structure, and each nephron is composed of two parts: renal corpuscle and renal tubule . What is the cause of kidney cysts? Will it become malignant?This Bosnian renal cyst grading system is mainly based on CT images of patients’ cysts for grading, according to the The thickness of the cyst wall of the renal cyst, whether there is division, whether there is calcification and enhancement, etc., are used for grading assessment, judging the possibility of benign and malignant cysts, and determining whether follow-up treatment or dynamic observation is required.

Let’s not make it particularly complicated, let’s briefly introduce you to the five levels of Bosnia:

  • Bosnia Class I: benign and simple Sexual cysts can be single or multiple. The wall of the cyst is very thin, there is no separation, calcification or solid components, and the content is liquid. The possibility of malignant cysts of this level is almost zero.
  • Bosnia Ⅱ: There may be a small number of thinner compartments in the cyst, and the cyst wall or compartment may contain small calcifications. The cyst should not exceed three centimeters. The boundary is clear, and the malignant probability of this level of cyst is almost zero.
  • Bosnia IIF grade: The number of cysts of this grade will increase significantly, there may be nodules and calcifications, and the cyst wall will be thicker, with a large diameter More than three centimeters, mostly located in the kidney. We can understand that most cysts of this level are benign, but the possibility of malignancy is not ruled out. The probability is about 5%.
  • Bosnia Ⅲ grade: This grade is an indeterminate cystic mass. The cyst wall is obviously thickened, and the cyst wall is irregular, and the separation is also significantly increased. This CT image consists of 40 ~60% are malignant tumors.
  • Bosnia Ⅳ grade: This grade has all the features of grade Ⅲ imaging. On this basis, relatively large solid masses of cystic or necrotic components can be seen, and the cysts are unevenly mixed and have enhanced soft tissue components The malignancy rate of this kind of MRI is 80% ~100%.

See the picture below, you may have a more intuitive understanding of this Bosnian classification , we only need to focus on the imaging performance of the cyst, An assessment can be made. Of course, we cannot rely solely on this Bosnian grading for evaluation, and sometimes rely on color Doppler ultrasound, MRI, and pathological biopsy for further diagnosis .

Summary

About the popular science of renal cysts, Dr. Xie wrote here for everyone. I believe everyone has already understood that if it is a single or less-occurring cyst, the cyst is not large and the nature is relatively uniform. In this case, we don’t need to put too much pressure on ourselves and perform regular color Doppler ultrasound Check and monitor it. Drink plenty of water, don’t stay up late, and eat lightly. If you have some medical diseases, you can actively adjust your own medical diseases.
