String Symptom

The String sign is the absence of physiological bends on an x-ray of the ureter, which may indicate tuberculosis of the kidneys and urinary tract. This is due to the rigidity of the affected ureteral wall, which does not allow it to bend as contrast material passes through it.

This symptom was described in 1956 by Russian researcher Anatoly Struna. He noticed that in tuberculosis of the kidneys and urinary tract, the X-ray shadow of the ureter does not have the usual bends, but remains straight. This was due to rigidity of the ureteral wall due to inflammation and swelling.

The String symptom is an important diagnostic sign that helps to establish the diagnosis of tuberculosis of the kidneys and urinary tract and prescribe appropriate treatment. However, additional tests such as blood tests, urine tests and kidney biopsies are necessary to confirm the diagnosis.

Overall, the String sign can be a very useful tool in the diagnosis of tuberculosis of the kidneys and urinary tract, especially in patients suspected of having this disease.

The string symptom is a specific sign that occurs during an X-ray examination of the genitourinary system and characterizes the condition of the urinary tract. This phenomenon arose due to changes in the urinary tract, which are caused by inflammatory processes or pathological changes.
