    Pyelography imaging offers detailed views of the pelveocalyceal system and ureter. Both retrograde and antegrade techniques are reviewed for their indications, methods, and complications.

    Area of Science:

    • Radiology
    • Urology

    Background:

    • Pyelography is a key imaging technique for the pelveocalyceal system and ureter.
    • Historically performed via retrograde catheterization, antegrade injection is now a common alternative, particularly for dilated tracts.

    Purpose of the Study:

    • To review the indications, techniques, and complications of pyelography.
    • To discuss interventional radiological procedures of the upper urinary tract.

    Main Methods:

    • Review of existing literature on pyelography techniques (retrograde and antegrade).
    • Discussion of interventional procedures including stent placement and balloon dilatation.

    Main Results:

    • Pyelography provides superior detail for the pelveocalyceal system and ureter.

  • Antegrade pyelography is an accepted alternative, especially in cases of upper urinary tract dilation.

    • Conclusions:

    • Both retrograde and antegrade pyelography have distinct advantages and disadvantages.
    • Radiologists increasingly perform therapeutic interventions via an antegrade approach.
