The cyst of the renal sinus of the left kidney is one of the types of neoplasms that can form in the organ. It belongs to the category of simple benign growths and, with timely diagnosis, as well as subsequent treatment, does not adversely affect human health. Despite the favorable prognosis, there are some features of the pathology that give reason to worry. Therefore, it is worthwhile to figure out - the sinus cyst of the kidney, whether it is dangerous for human life, and what complications it can lead to.
General information
Cystic formations in the kidneys are thin-walled round growths, clearly limited from other tissues. They have a cavity that is filled with serous fluid. The term "renal sinus cyst" refers to the location of the neoplasm directly near the vascular portal of the kidney. In this case, the growth is not in contact with the body.
According to cyst statistics, the renal sinus of the left kidney is diagnosed much more often than the right. And also there are cases of damage to both parts of the paired organ at the same time.
The main provoking factor for the appearance of a neoplasm is an increase in the clearance in the lymph nodes. Despite the fact that the sinus cyst of the kidney is considered a benign growth and is diagnosed much more often than other types, the risk of complications is present, and therefore its growth is subject to constant monitoring by an experienced specialist.
Most often, the pathology is diagnosed in women older than 50 years.
Symptoms
At the initial stage of development, it is quite difficult to identify the cyst of the renal sinus of the left kidney , since the pathological process develops completely asymptomatically. In most cases, a small growth can be detected by chance during a regular physical examination or examination for other diseases in the body.
But as the neoplasm grows, its size increases, which increases pressure on adjacent tissues and blood vessels. This begins to affect the functioning of the urinary system and the well-being of the patient. Often people attribute these unpleasant feelings to other diseases and try to treat on their own, which leads to a loss of time and exacerbates the situation.
The main signs by which organ damage can be recognized:
- drawing pain in the lumbar region on the left side;
- sustained high blood pressure, which cannot be normalized with conventional medications;
- frequent urination or urinary retention in the body, which is provoked by the pressure of the neoplasm on the bladder and ureter;
- general weakness;
- causeless apathy;
- bouts of nausea;
- dizziness;
- visual impairment.
With the formation of several growths in the kidney, the symptoms will be much stronger. In this case, the person feels severe aching pain on the left side, combined with scanty urination.
If blood excretion enters the urine, its color changes, so when this symptom appears, you should not postpone the visit to the doctor.
Causes
In most cases, the cause of the cyst of the renal sinus of the left kidney is a violation of the development of the fetus in the womb. The likelihood of a build-up increases if close relatives have been diagnosed with cases of this pathology.
Various factors can also provoke the appearance of a cyst:
- excessive physical labor;
- lower back injury, a fall from a height;
- infections of the urinary system, kidneys;
- excessive alcohol consumption;
- pyelonephritis;
- unbalanced nutrition;
- hormonal disbalance;
- bad ecology;
- regular hypothermia of the body;
- urolithiasis disease;
- uncontrolled medication.
If the kidney hurts on the left side, the symptoms and treatment of the pathological process can vary significantly. Therefore, you should not try to establish a diagnosis yourself, and even more so to carry out treatment, as this can provoke a further worsening of the situation.
Effects
The lack of timely treatment for cysts of the renal sinus of the left kidney can lead to the development of complicated pyelonephritis and renal failure.
With a significant growth of the growth, the risk of its rupture with a further release of pus to the adjacent organs and tissues increases. This can lead to intoxication of the body.
In addition, an increase in the size of the neoplasm leads to displacement of the tissues of the organ, as a result of which hydronephrosis develops, which threatens with a loss of functionality of the affected kidney.
Any of these complications can cause serious damage to human health, so only timely treatment will help to avoid this.
Diagnostics
To identify a pathological growth, several types of diagnostic studies and laboratory tests are prescribed. This is due to the fact that in most cases the pathology develops asymptomatically, which greatly complicates the diagnosis. Only with the totality of the data obtained, the doctor can make a conclusion and prescribe the appropriate treatment.
The main diagnostic methods:
- Analysis of urine. An increased level of red blood cells indicates the development of an inflammatory process in the body.
- Blood analysis. To detect the erythrocyte sedimentation rate.
- Ultrasound The main method for diagnosing a pathological organ change. Echographic signs of a cyst of the renal sinus of the left kidney are manifested by black rounded formations with clearly defined borders that do not communicate with the pelvis. In this case, you should not confuse a cyst with hydronephrosis, lymphangiosis, and kidney limamotosis.
- CT To identify pathology, a special dye (iodine) is introduced into the body. After 10 minutes, when the pigment spreads throughout the body, it can be concluded that there is a cyst, since the fluid-containing formation does not connect to the kidney and therefore does not stain like other tissues.
- MRI This method helps to identify a sinus cyst with hyperintensity of the signal in the T2-VI mode and hypointensity in the T1-VI.
What diagnostic methods to appoint the doctor decides will depend on the complexity of the case and the presence of additional symptoms.
Conservative treatment
In the absence of unpleasant signs and active growth of the cyst, treatment is not carried out. In this case, the patient should undergo regular examination to identify the dynamics of the development of the neoplasm.
Medication for cysts of the renal sinus of the left kidney is prescribed for a small growth (up to 5 mm), but the patient feels uncomfortable discomfort. Therapy in this case is aimed at eliminating the symptoms, normalizing the outflow of urine and stabilizing the level of blood pressure.
For treatment, the doctor prescribes painkillers, anti-inflammatory drugs, as well as antispasmodics. If necessary, the use of antibiotics is permissible. The treatment regimen and dosage are determined by a specialist, based on the individual characteristics of the patient, the totality of symptoms and the stage of development of the cyst.
With timely diagnosis and adequate therapy, you can get rid of the pathology without surgical removal.
Indications for the operation
For patients in whom the appearance of a sinus cyst of the kidney has led to the development of complications, surgical removal of the growth is recommended, since any delay can be life-threatening.
The main indications for the operation:
- suppuration of the neoplasm;
- rupture of a cyst of the renal sinus of the left kidney;
- critical urinary retention;
- loss of organ functionality;
- the likelihood of degeneration into a malignant tumor;
- rapid growth of the cyst;
- the presence of blood in the urine;
- acute pain from the affected organ;
- persistent hypertension, which cannot be stabilized over a long period.
Surgical removal
There are several ways to remove a sinus cyst. Which to choose? This is determined by the doctor on the basis of existing evidence.
The main types of surgery:
- Puncture of the cyst. During the operation, a cyst is punctured with a special tube. Through it, the serous fluid of the growth is pumped out, followed by filling the void with a special solution that glues the walls of the formation. If this is not done, then the probability of relapse is 80%.
- Laparoscopy of a kidney cyst. The operation is performed under general anesthesia. To remove the cyst, several small incisions are made in the anterior wall of the abdominal cavity and from the side directly near the affected organ. A laparoscope and other necessary instruments are inserted through the openings. Then carbon dioxide is injected into the abdominal cavity, helping to lift the peritoneum. After this, the cyst is excised. At the end of the operation, all incisions are sutured. Advantages of the method: short rehabilitation period (5-7 days), lack of scars, quick healing of wounds, minimal likelihood of adhesions.
After the operation, the patient should wear a bandage, and work should be carried out no earlier than 2 weeks later. This will help to avoid the development of complications.
Folk remedies
With a small cyst of the renal sinus of the left kidney and the absence of painful symptoms, further growth of the growth can be prevented with the help of folk remedies. Their use must first be agreed with the attending physician.
The most effective means:
- Burdock. Pour the crushed grass root (30 g) into boiling water (0.5 l). Boil the mixture for 20 minutes, not allowing much to simmer. Pour the broth into a thermos, insist 60 minutes, clean. Drink daily 3 times a day, 100 ml at a time.
- Golden mustache. Fold 50 g of grass in a glass container. Pour in 500 ml vodka. Insist in the dark for 10 days, periodically shaking the mixture. After the time has passed, clean the tincture of impurities and drink daily 30 minutes before meals 2 times a day. Take the first day 10 drops per 30 ml of water, with each subsequent day increase the dosage by 1 drop, and so on for 20 days. Then repeat the course, but with a decrease in the daily norm by 1 drop.
- Elecampane. Pour warm water with a volume of 2.5 liters into a glass container. Pour into a liquid 30 g of crushed elecampane root, 50 g of sugar and 5 g of yeast. Put the container with the product in the dark until the drink begins to ferment. Drink the medicine in 100 ml daily for 20 consecutive days.
- Aspen Bark. Grind the component to a powder consistency. Take thrice a day for 1 tsp., Washed down with warm water. The full course is 14 days, after taking a break for the same period of time, and then repeat the therapy.
Prevention
Compliance with simple rules of prevention will help minimize the likelihood of a sinus cyst.
- Avoid hypothermia, dress according to the weather.
- Reduce salt intake to 2-2.5 g per day.
- Drink at least 1.5-2 liters of water daily.
- Completely refuse tea, coffee, alcohol.
- Keep fried, spicy, salty, and smoked foods to a minimum.
- Promptly treat infectious diseases.
- Limit chocolate intake.
conclusions
Despite the fact that the cyst of the renal sinus of the left kidney belongs to the category of simple types of education, the likelihood of complications is still present. The risk increases if you ignore the obvious symptoms of the pathological process.
In addition, if the kidney hurts on the left side, the symptoms and treatment can radically differ, therefore, self-medication, based on the experience of your friends, is not worth it, because any wrong step can trigger increased growth of the growth and its suppuration. Therefore, before undertaking anything, you should undergo an examination and consult a doctor.
