Pyeloureterography (PUG) is an x-ray method for examining the urinary tract, which allows you to assess the condition of the kidneys and ureters. This method is used to diagnose various diseases of the urinary tract, such as kidney stones, tumors, infectious diseases, etc.
PUG is performed as follows: the patient is injected intravenously with a contrast agent, which is then excreted by the kidneys. An x-ray of the urinary tract is then taken. The image shows the shape and size of the ureters, the presence of stones or tumors.
Advantages of PUG:
– High diagnostic accuracy;
– Possibility of detecting stones and tumors in the early stages;
– Low radiation dose;
– Non-invasiveness of the method.
Disadvantages of PUG:
– The need to administer a contrast agent;
– Risk of allergic reactions to the contrast agent;
– Restrictions on use in pregnant women and children.
In general, PUG is an effective method for diagnosing urinary tract diseases and allows for timely detection and initiation of treatment.
