Pyeloureterography Intravenous

Pyeloureterography (P.) is a method of x-ray examination of the urinary tract, which allows you to assess the condition of the kidneys and ureters. This method is used to diagnose various kidney and urinary tract diseases such as kidney stones, tumors, infections, etc.

There are two main methods of performing P.: intravenous pyeloureterography and retrograde pyeloureterography.

Intravenous pyeloureterography is a method in which a contrast agent is injected intravenously and then an X-ray examination of the urinary tract is performed. This method is the most common and provides a clear image of the urinary tract at all levels.

Retrograde pyeloureterography is a method in which contrast is injected directly into the bladder through the urethra. This method allows you to image the urinary tract only at the level of the ureters and kidneys.

Both methods have their advantages and disadvantages. Intravenous pyeloureterography provides a clearer image of the urinary tract and more accurately determines its condition, but may be more painful for the patient. Retrograde pyeloureterography is less painful but produces a less clear image.

In general, the choice of method for performing pyeloureterography depends on the specific clinical situation and physician preferences.

**Pyeloureterography**** intravenous** *(pielouretero)-* is a method of x-ray examination of the urinary tract, combining intravenous and intravesical administration of a contrast agent. The main goal of the technique is to identify abnormalities of both the urinary and genitourinary tracts. The main value of the method is that it makes it possible to simultaneously assess changes in the kidneys, bladder and ureters, as well as clarify the condition of the urethra. Important advantages of the method are high image contrast and the ability to more accurately determine the degree of narrowing of the urethra than using other methods.
