Bacterium: causes, symptoms, diagnosis. How to treat

The presence of bacteria in the urine is called bacteriuria. In a healthy state, urine is completely free of microorganisms. Bacteriuria suggests the presence of inflammatory processes in the kidney and urinary system. However, the presence of bacteria in the urine sediment after centrifugation is clinically important.

The character of bacteriuria is expressed by the designation - the titre of microbial bodies, which is 104-105 cfu in 1 milliliter of urine. When the titer grows to 104 cfu /ml, then I diagnose bacteriuria.

It should be borne in mind that such results have a conditional form, therefore, each separate clinical case needs to be adjusted.

Determine the violation can be in several ways: a reduction glucose test, a nitrite Griss test and a TTX test.

In polyclinics, chemical studies are used to obtain quick results. Quantitative bacteriological types of research make it possible to accurately determine the extent of disturbances and the number of bacterial colonies. There may be deviations in the results in case of abundant drinking, reception of uroseptics and so on. After the diagnosis is made, the type of microorganisms, their susceptibility to antibiotic drugs and sulfonamides are determined.

The causes of bacteriuria

If the kidneys are not sick and have no defects, then the bacteria can not get out of the blood into the urine. The disease is diagnosed in inflammatory processes in the kidneys with renal involvement of the parenchyma by bacteria, with infection of the bladder, inflammation of the prostate. In addition, the cause may be the provocation by catheterization of the ureters and bladder, the introduction of bougie into the urethra, examination of the inner part of the walls of the bladder (cystoscopy).

The forms of bacteriuria are different and acquire a severe type with such deviations:

  • Blockage of the ureters by concrement, when abnormalities are formed during contractions, as a result of which already infected urine gets back into the kidney. In addition, there are other causes of improper outflow from the upper urinary tract.

  • The adenoma of the prostate, leading to the appearance of inflammation, causes bacteriuria. The aggravation of the urinary tract and the retention of urine may aggravate the disease.

  • The path of infection with bacteriuria can be downward and upward.

    The first type is characterized by the ingress of pathogens from an inflamed bladder, an infected kidney, a prostate that has hyperplastic glandular tissue. Ascending form of urine infection is the entry of bacteria into urine due to improper catheterization, urological endoscopy - cystoscopy, bougie. The source can also become the large intestine and the vulva, if a person does not adhere to simple standards of personal hygiene.

    The disease is fixed in case of such bacteria as streptococci, intestinal and pseudomonas aeruginosa, staphylococci and proteins. Any kind of bacteria, after reaching the genitourinary system, provokes inflammation of the urinary system or kidneys. Infection can occur in some areas of the colon, causing proctitis. Bacteriuria is noted in people suffering from permanent constipation, hemorrhoids. Not so often the disease occurs in people with brucellosis, abdominal typhoid, paratyphoid and leptospirosis - due to the fact that these diseases are not so prevalent.


    Symptomatic of bacteriuria

    Bacteriuria manifests itself against the background of the disease that caused it. Often it is fixed with pyelonephritis and cystitis.

    In addition, bacteriuria may indicate the presence of such diseases:

  • BPH;

  • chronic prostatitis and its progressive stage;

  • diabetes;

  • bacterial sepsis;

  • urethritis.

  • For this list of diseases, the symptoms are nonspecific, they make it possible to determine nosology only through laboratory tests of urine.

    Symptoms that are similar to those that indicate pyelonephritis:

  • dysuria - accelerated or too slow devastation of the bladder, the presence of burning and pain;

  • uncontrolled allocation of urine;

  • flashes of nausea, sudden desires for vomiting;

  • rapid increase in body temperature, trembling;

  • subfebrile fever lasting 7-14 days;

  • painful manifestations in the region of the bladder;

  • turbidity of urine, which has an unpleasant odor, uncharacteristic of urine, often with particles of pus.

  • Symptoms similar to those of urethritis:

  • excretion from the urethra, often with pus;

  • urination accompanied by painful sensations, dysuria;

  • hyperemia of the edges of the urethra, irritation, itching;

  • painful manifestations in the perineal region;

  • increased temperature, trembling;

  • a change in the worse for the state of the whole organism, a decline in strength.

  • Symptoms of the disease, similar to the signs of cystitis:

  • dysuria - too frequent urination accompanied by pain;

  • itching during urination;

  • frequent desire to empty the bladder with a small amount of urine;

  • uncharacteristic odor of urine;

  • modification of the color of urine and loss of its transparency;

  • unceasing pain, aching in the lower abdomen;

  • an increase in body temperature is not excluded;

  • excretion from the urethra, sometimes with pus.

  • True and false bacteriuria

    True bacteriuria is characterized by the ingress of microorganisms into the urinary tract, followed by reproduction and the evocation of an acute inflammatory process.

    The false form of bacteriuria is characterized by the ingress of microorganisms into the bladder and ureters, but in the future they do not multiply and do not affect the cells due to the patient's normal immunity or taking antibiotics at the moment due to inflammation.

    Hidden and asymptomatic type of bacteriuria

    A hidden type of the disease is often diagnosed at the time of scheduled clinical examination in patients with no complaints of the bladder, urination and kidneys.

    In most cases, the asymptomatic type of the disease is diagnosed in the female. If men have found asymptomatic bacteriuria during the monitoring survey, an additional search for hidden prostatitis should be carried out. In addition, often latent bacteriuria is diagnosed in patients 65 years of age and older - in this case it has a chronic multi-year form. In most cases, men have asymptomatic bacteriuria with prostatic hyperplasia and a deviation in the functioning of the urine outflow, in which the number of pathogens increases. In elderly people, this indicator is usually not a threat, because the studied bacteria are pathogenic.

    Treatment of bacteriuria

    The presence of any type of bacteria in urine indicates the likelihood of inflammation in the urogenital system. The definition of medications for the treatment of a disease depends on the complexity of the disease, the age of the patient and his condition.

    Inflammation of the severe form is treated with the newest antibiotics of a wide range of effects with a minimized list of adverse effects. For the treatment of chronic inflammations, additional microorganism tests for bacteriuria will be required, as well as an antibioticogram to determine the susceptibility of the microorganisms of the infectious-inflammatory disease to antimicrobial agents.

    Neutralize the disorder does not follow people with diabetes, with a urinary catheter, the elderly and young people who have organic abnormalities of the urinary system. If immunosuppression is not observed, then such treatment is also not necessary, but only in the absence of structural anomalies of the urinary tract. It is worth emphasizing that sometimes, when antibiotic therapy is carried out, the normal flora is replaced by a pathogenic one.
