Pyelography Percutaneous

Percutaneous pyelography

Percutaneous pyelography is a method of x-ray examination of the kidneys and urinary tract, in which a contrast agent is injected percutaneously (through the skin) into the renal pelvis.

Percutaneous pyelography refers to antegrade research methods, that is, contrast is introduced into the lumen of the renal pelvis and ureter along the urine flow. This allows you to obtain an image of the renal collecting system, ureter and bladder.

When performing percutaneous pyelography, the doctor punctures the renal pelvis with a thin needle through the skin under ultrasound or x-ray guidance. A non-ionic radiopaque contrast agent is then injected through the needle. After this, X-rays of the kidneys and urinary tract are taken in various projections.

Percutaneous pyelography can detect changes in the renal pelvis and ureter, stones, narrowing, and developmental abnormalities. This method has high diagnostic value and minimal risk of complications.

Percutaneous pyelography For the article, use the description below: Percutaneous pyelography is an x-ray examination of the kidneys, which consists of introducing a contrast agent into the renal pelvis to a depth of no more than 2-3 cm, and then radiography it. Before the examination, the patient is often placed in a lateral position to reduce venous return of blood to the kidneys. If necessary, catheterization of the vein can be performed to provide rapid access to the vein. Through a thin needle inserted into the adrenal gland under direct x-ray control, a “thick needle” with a mandrel at the end is pushed to the upper pole of the kidney. After insertion of the needle, air is released from
