August 12, 2017 17:52 | Urinary Systems.

pyonephrosis - a purulent fusion of the kidney tissue with the formation of an abscess.When this mixture is kidney pus parenchymal tissue, urine and possibly stones.Pyonephrosis is the final stage of chronic inflammatory diseases of the kidneys.

reasons pyonephrosis

immediate cause pyonephrosis is pathogenic microflora, which affects pyelocaliceal organ system.As a result of its contamination develops first inflammatory and later purulent process.With inadequate treatment or lowered immune defense, purulent process progresses rapidly and spreads.It affects the kidney tissue, which are amenable to purulent fusion.All that can be done in this situation, a weakened immune system, is to limit the process of surrounding tissues.As a result, a large abscess, which is located on the background of the former kidney.

primary reasons for kidney infection can be many.Most often, it is hit by urinary tract infection, which can be in setting non-sterile urethral catheter or with inflammatory diseases of the exte

rnal genitalia.

Another one of the causes can act pyonephrosis penetrating trauma or lumbar region of infection by blood flow from chronic lesions.Chronic foci of infection in the human body, often are slow-progressive ear infections, throat and nasal sinuses, which must be on time and properly sanitize.

Symptoms pyonephrosis

complexity of clinical pyonephrosis is that it is superimposed on the preceding symptoms of the disease.For example, pyonephrosis develops after pyelonephritis, which is accompanied by very similar symptoms.

bud at pyonephrosis

the fore when pyonephrosis out common symptoms, which is characterized by weakness, fatigue, sweating, paleness, insomnia.At the same time, clearly defined and local symptoms.For pyonephrosis characteristic symptoms are dull pain in the lumbar region, which may be given in the lower abdomen and the area of ​​the external genitalia.Determined positive symptom Pasternatskogo, in the form of increased pain in the lumbar region at tapping into this area.

Another characteristic is pyonephrosis urinary syndrome.It manifests itself as a change in urine.Visually, it is placed with more turbid flakes.If the urine to stand, then in a short time at the bottom cup formed precipitate of approximately 1/4 of the liquid.

Thus, if you notice a deterioration in his general condition, the change in color of urine or pain in the lumbar region, you need to see a urologist immediately for diagnosis and treatment.

Diagnostics pyonephrosis

Diagnostics pyonephrosis, like any other diseases of the genitourinary system, begins with common blood and urine .The general analysis of blood will be observed an increased number of leukocytes, leukocyte formula shift to the left with the appearance of plasma cells.The general analysis of urine will also mark a large number of white blood cells, and bacteria, which in the normal state is absent.

One of the specific methods of diagnostics pyonephrosis is cystochromoscopy , which comprises administering intravenously a solution of indigo followed by inspection of the bladder endoscope.When pyonephrosis noted the complete absence of the selection of the solution on the affected side or rapid turbidity of wash liquid.

On Review radiography organs of the abdominal cavity with pyonephrosis unable to determine the shadow enlarged kidneys and the absence of contour lumbar muscles.During the same excretory radiographic contrast material or delays in the kidney or in general it does not fall.

for more accurate diagnosis to date used computed tomography and ultrasonography.They can be used to determine the location and nature of the disease process in the kidney.

kidney ultrasound at pyonephrosis

the purpose of differential diagnosis with kidney tumor pyonephrosis held aspiration needle biopsy under ultrasound control .After aspirate examination under the electron microscope can be revealed purulent detritus or atypical cells.In the first case, the results of the study suggest pyonephrosis, while the second - a malignant tumor.

Treatment pyonephrosis

Tactics pyonephrosis treatment is to remove the purulent focus.The most common operation is performed on the kidney removal, which is called nephrectomy .If the patient's condition is very relaxed, the nephrectomy can be performed in two stages, the first of which is the operation of the installation tube to drain urine, and the second - already directly organ removal.If purulent destruction of the kidney with the ureter passes on, then the method of choice in the treatment of pyonephrosis is surgery to remove the kidney and ureter - nephroureterectomy .

Following the surgery the patient is assigned to a course of antibiotic therapy.It is the use of broad-spectrum antibiotics.Among them are the antibiotics from the group of cephalosporins and fluoroquinolones.For example, drugs like tsetriakson and ofloxacin.But to use them, because of the many side effects, it is recommended only after consulting a specialist.

Feeding habits and lifestyle with pyonephrosis

after a kidney removal, the patient to place the surgical wound is placed a few tubes for drainage.At the time of their patients are advised to wear gentle treatment to the wound heal properly.

With regard to nutrition, as with any other disease of the kidneys, at 7 pyonephrosis recommended dietary table by Pevzner.It is to eliminate the use of alcoholic beverages, coffee, strong tea, salty and acidic foods.Considering that after the treatment the patient remains pyonephrosis only one kidney, diet regime food it must be observed throughout the rest of his life.

rehabilitation after pyonephrosis

Since the treatment pyonephrosis appointed antibiotics in large doses, patients in need of restoration of normal intestinal microflora.For this purpose, the preparations containing normal bacteria.These medicines like Hilak Lactobacterin or can be purchased at any pharmacy without a prescription.

in the long term patients are recommended a trip to the resorts with mineral and mud treatments.Among these resorts by far the most popular are the Salem and Morshyn.Clinical trials show that patients who regularly take courses of sanatorium treatment, have a much lower risk of recurrent suppurative kidney disease.

pyonephrosis Treatment folk remedies

Treatment of folk remedies in the early stages of the disease nothing but progress of pathology, not the end.And if we talk about the national treatment in the later stages, at this stage it can even be life threatening.

When kidney disease all traditional medicine usually recommends the use of diuretic decoctions and infusions of various herbs.When purulent inflammation may contribute only a generalization of infection with serious consequences.

Complications pyonephrosis

Before talking about the complications pyonephrosis, you must remember that he has pyonephrosis is a complication of inflammatory kidney diseases as pyelonephritis, glomerulonephritis and others.

The most severe complication of sepsis pyonephrosis.By this means the medical term total systemic inflammatory reaction, which develops due to the large number of contact toxic metabolites in blood.That is, in fact, bacterial shock can develop at pyonephrosis.

consequences of the generalization of infection is the formation of metastatic abscesses in various organs.Most often suffer from ulcers of the liver, which in this situation very quickly gives decompensation of all organs and systems, and holds to death.

There are local complications pyonephrosis.For example, at break of an abscess in the perirenal tissue will develop secondary paranephritis, and in breaking out of an abscess - a renal fistula.Worth noting that these fistulas, due to persistent urinary Zatoka, have a very bad tendency to healing.

addition, due to the increased load on the kidney in the second it can develop amyloidosis - a disease which is characterized by the deposition in the renal parenchyma pathological amyloid protein.

Prevention pyonephrosis

First of all, pyonephrosis prevention should be aimed at preventing the occurrence of inflammatory diseases of the kidneys.The first item in this should be to avoid hypothermia, which immediately affect the functional state of the kidneys.

important factor in prevention is pyonephrosis readjustment of foci of chronic infection, and adequate treatment of inflammatory diseases of the urinary tract.For readjustment of foci of chronic infection using different treatments.For example, in the presence of patients with chronic sinusitis should consult an otolaryngologist to carry out sanitizing operations in the future.

Adequate treatment of inflammatory diseases of the urinary tract is the timely use of antibiotics to eliminate infectious disease component.Antibiotics better as a result of bacteriological examination of blood and urine tests on the sensitivity of bacteria to antibiotics.If we make such a study does not provide, prescribe broad-spectrum antibiotics.


Forecast for life - relatively favorable.With adequate timely treatment pyonephrosis patients have a much greater chance of recovery.Forecast for the job - a poor, because even with professional timely treatment of patients lose their kidneys, and get a second disability group, which the law provides for a pension.The prognosis for recovery, as well as the prognosis for life is relatively favorable.The chance for recovery occurs only in patients with early treatment.But even with such therapy does not have to rely on the preservation of the kidneys as the body.
