How to Distinguish Between Renal Cyst and Renal Tumor

Renal cyst is a relatively common disease, number of cases a lot in life, but many patients with renal cyst friends consultation, the difference between the renal cysts and tumors, more will bear renal cyst developed into the tumor, for that matter, we consulted medical experts.Experts give a the answer below.Hope to is to help friends from it.

Renal cyst is not a tumor, but easily confused with tumor, so the renal cyst and renal malignant tumor of the identification is very important.

The identification of both available renal ct angiography or renal artery angiography.Computed tomography of renal parenchyma, cyst shallow parts of the image, tumor site image deep;Renal arteriography, the cyst part blood vessels are sparse, no contrast medium thick poly, kidney malignant tumor by rich blood vessels, with contrast agents together.Doubt cyst of malignant change, can be cyst puncture, fluid can be taken out for routine inspection and exfoliated cells;Can also be used to cyst injection of contrast agent, look for tumor capsule wall.Type B ultrasonography and computed tomography (CT) is easy to differentiate renal cyst and renal tumors.

Anyway, renal cyst is not connected with the outside world of occurrence in kidney size of cystic masses of the general, common renal cysts can be divided into adult type simple renal cysts and polycystic kidney, acquired renal cyst.
Renal tumors account for about 2% ~ 3% of all human tumors, including benign tumors and malignant tumors.Common benign tumors have renal adenoma, structure of the tumor, renal hemangioma, near the ball unit cell tumor and renal cyst, etc., and kidney malignant tumor, with renal cell carcinoma, carcinoma of the renal pelvis and renal tumor more see.


Medical expert reminds, renal cyst patients unnecessary worry too much, renal cysts and tumors in medicine are essentially different things, at the same time, the best way to patients with renal cyst is go to a hospital checking regularly, look at the size of the cyst, and whether the lesions.

What are the Types of Renal Cyst

First, adult renal cyst

Adult renal cyst is a congenital genetic disease, inside kidney essence is filled with countless sizes circular renal cyst is not interlinked with the outside world.Characterized by increased night urine, back pain, hypertension, etc.Urine has blood in the urine, a small amount of proteinuria, often slowly become chronic renal failure.10% of people with kidney stones, 30% of people with polycystic liver.Experienced doctors with b-ultrasound, intravenous urography imaging can be confirmed.

Second, the simple renal cysts

May is a congenital anomaly, it is unilateral or bilateral renal and have one or several sizes of the lumen of the circle is not interlinked with the outside world, the majority is unilateral, therefore calls simple renal cysts.Its incidence can be increased age casually, over 50 people do B to exceed, 50% can be found that the cysts.With the aid of ultrasound, CT can be confirmed.

Third, acquired renal cyst

Is mainly due to uremia or occurred after dialysis treatment.Has nothing to do with age, and associated with hemodialysis time.Had no renal cysts, according to reports in the literature, dialysis for more than 3 years, most patients will appear a cyst.It's at least four within a kidney cyst, some can cyst infection occurs, even cancer, ultrasound or CT examination can be confirmed.


Know some type of renal cyst is very useful, will help better disease treatment in time.If you have any questions, please contact me at liu476qiang@gmail.com.

Five Kinds of Symptoms of Kidney Failure

Symptoms: cardiovascular system

Patients often have high blood pressure or heart failure symptoms, often feel palpitations or asthma, most of the time not to lie down, rhythm of the heart also easily disorder, serious patient can appear sometimes the phenomenon of pericardial effusion, sometimes will also blocked.

Symptom 2: the nervous system

Occurred after the disease will be depressed, headache, dizziness phenomenon, some patients with memory will suddenly drop, the symptom such as insomnia, dysuria and often can be seen, serious will happen coma patients.

Symptoms 3: the digestive system

After the occurrence of the disease patients often feel anorexia, nausea, vomiting, diarrhea, often feel his mouth the smell of urine, or gastrointestinal bleeding, etc.

Symptoms 4: the skin

Occurs when the disease will have desquamation phenomenon, the skin also often feel there is no luster, sometimes there will be composed of melanin, the skin color will appear darker, appear edema, or skin infection etc. Bad phenomenon.

Symptoms 5: respiratory system

The disease happens in our respiratory system also has an effect, the mouth of the often feel the smell of urine, respiratory and metabolic acidosis gas, there will be such a bad feeling.


Above all, we know the early symptoms of kidney failure is the main five above, so the disease occurs, special attention should be paid attention to the body of all kinds of symptom, so early treatment, comprehensive treatment, recover as soon as possible.

Drinking too Much was Susceptible to Kidney Failure

Beer for men is a very popular drink, especially in hot weather to go out to eat snack or friends, can drink a few cups.However, drinking beer too much harm to the body.People with kidney disease, in particular, how to drink beer also aggravate kidney burden, serious can lead to kidney failure.

Drink beer too much to let you to renal failure

Beer contains alcohol, the alcohol will increase the burden of the kidney in the metabolic process.At the same time the hops in beer has diuretic effect, also can increase the burden of the kidney.At the same time will also hurt liver, liver injury after the toxic substances will not be able to, very good to further increase the kidney burden.If you have already suffered from kidney disease, and often a lot of beer, can make uric acid deposition in renal tubular obstruction, cause kidney failure.

Methods to prevent deterioration of kidney failure

Once got the kidney failure, can bring a lot of pain to patients.To prevent deterioration is mainly has the following kinds.

1. In life, patients should prevent infection, especially for respiratory tract and urinary tract infection is the most common, prevent infection in preventing chronic renal failure deterioration have a positive effect.

2. Patients should try to prevent the height of their blood pressure, blood pressure is the most common symptoms of chronic renal failure, but still too high blood pressure can affect kidney function.Antihypertensive therapy can improve renal function in different degrees.

3. When eating drug, patients should avoid substances harmful to the kidneys, and renal toxicity drugs, such as antibiotics, such as amino sugar type non-steroidal anti-inflammatory drugs and so on.

4. Patients should strengthen the understanding of her condition, with some symptoms can determine their own illness, such as nausea and vomiting, diarrhea, excessive diuresis and insufficient water intake, etc.


5. In patients with kidney disease diet, should keep a reasonable diet, so for the treatment of renal failure has a very important role.

The Diagnosis of PKD

Kidney disease is found that the sooner, the more easy to cure, PKD treatment also is such, so how to diagnose PKD.

Clinical manifestations of kidneys, such as abnormal urine, high blood pressure should be confused with the possibility of the disease, such as family history, can remind the disease more.Type B ultrasonography, computed tomography (CT) and magnetic resonance imaging can find procuratorial characteristic double renal cyst, diagnosis can be established.The disease early renal cyst number matter, can is a unilateral, a few years to review such as renal cyst populations outside or renal cysts, the diagnosis of ADPKD may also be must be.In recent years, the application of 3 'HVR, PGP and 24-1, such as DNA probe, using gene linkage analysis diagnosis of cyst is very reliable, can check out the heterozygote family members and asymptomatic patients.The diagnosis of the disease mainly rely on the following procuratorial rear can determine the exclusion of all other related diseases.

CT scan favorable excluded renal tumors.MRI examination can better help identify other cystic, and identification of congenital hydronephrosis.The part of the cyst, distribution, number, size, and renal pelvis calyces are interlinked, and do you have any high blood pressure, or complications such as recurrent urinary tract infections, can help identify the renal capsule sexual disease.
In patients with milder symptoms, the disease is often misdiagnosed as simple renal cysts, isolation, multilocular cyst multiple simple cysts, such as family history, and at the same time can help the differential diagnosis of hepatic cyst.


Haematuria occurred with new creatures, cause blood in the urine of other diseases such as kidney stones were identified, pay attention to the concurrent polycystic kidney stones or cyst canceration, etc., should be line coagulation screening (PT, APTT and platelets), hemorrhagic disease.About a family history of subarachnoid hemorrhage patients with cerebral MRI examination.

How to Diagnose Chronic Nephritis

Chronic nephritis is a set of more etiology of chronic glomerular disease primarily glomerular disease, but most of the patients with chronic nephritis unknown etiology, so kidney disease symptoms, the diagnosis of chronic nephritis is difficult.So, how to diagnose patients with chronic nephritis?

1, the kidney injury and secondary systemic disease identification, many secondary renal damage caused by systemic diseases, its performance nephritis.Such as allergic purpura nephritis, diabetic nephropathy, gouty nephropathy, multiple myeloma, infective endocarditis, attention and identification of nephritis.

2, chronic pyelonephritis late check has apparently similar to glomerulonephritis proteinuria and hypertension, but chronic pyelonephritis, see more at women in the history of history of urinary tract infection, urinary sediment procuratorial more white blood cells, or leukocytes tube type, such as bacteria or smear can find positive urine culture more help to the diagnosis.Renal damage in a patient with chronic pyelonephritis is given priority to with renal tubular damage, proteinuria has the characteristics of renal tubular proteins.Renal vein angiography of the renal pelvis, isotope renography and scanning, the asymmetry of kidney damage on both sides, can be used as the important basis of differential diagnosis.

3, primary long illness hypertension also cause kidney damage, appear abnormal changes of urine.But the amount of proteinuria is often less, rarely persistent nixie and red blood cell tube type.Generally no anemia and hypoalbuminemia, if you have kidney damage, the extent and nephritis.Identification of primary hypertension with glomerulonephritis hypertension, history is very important, the former a prior history of high blood pressure, then the first have proteinuria, renal biopsies procuratorial identification is feasible.

What is the Proteinuria

Under normal circumstances, as the glomerular filtration effect on the choice of plasma protein and renal tubular heavy drain function, people only contains trace protein in urine, ingredients include:
(1) plasma proteins, due to stop the glomerular capillary on the plasma macromolecular protein, it mainly for the urine in the medium and small molecules plasma proteins such as albumin, 2 microglobulin immunoglobulin light chain, beta, and some enzymes such as lysozyme, amylase and lactate dehydrogenase, etc.

(2) urinary tract secretion proteins, mainly for renal tubular secretion or damage out of the protein such as Tamm Horsfall protein and urinary tract secretion or injury, inflammation effusion protein, etc.Because the quantity is little, qualitative procuratorial negatie urine protein, urine stereotypes 24 hours urinary protein quantitative is generally not more than 150 mg.When urine protein content is more than the normal range, qualitative procuratorial urine protein positive urine stereotypes or 24 hours urinary protein quantitative 150 mg is the proteinuria.

Proteinuria can be divided into:

(1) functional urinary system without organic disease, urinary protein temporary to appear, to a lesser degree, short duration, triggers can be faded after lifting.More because of the factors of internal and external environment changes such as body strong motion, fever, cold stimulation, mental stress, the sympathetic nervous excitement, and the application of vascular active agent of renal vascular spasm or congestion caused by temporary sexual function change, increase glomerular capillary wall permeability.When the influence factors to eliminate, urine protein natural dies.24 hours urinary protein quantitative generally less than 0.5 g, see more at teenagers.


(2) orthostatic proteinuria is also called sexual proteinuria.In establishing or spine lordosis of proteinuria.Set position, may lordosis spinal compression renal vein or set down for too long the kidney, the renal vein distortion caused by renal vein blood, lymph and blood circulation suffocate.Its characteristics for a morning or decubitus negatie urine protein, activity or long up getting up, urine protein positive, lay down and then negative.Quantitative generally less than lg, 24 hours urinary protein found in young people.
