    Area of Science:

    • Urology
    • Interventional Radiology

    Background:

    • Percutaneous nephrostomy is a common procedure for managing upper urinary tract obstruction.
    • Temporary urinary drainage is often required for various urological conditions.

    Purpose of the Study:

    • To describe a detailed technique for percutaneous nephrostomy using angiographic equipment.
    • To provide a method for establishing temporary urinary drainage lasting several weeks or months.

    Main Methods:

    • Patients are positioned prone oblique after intravenous contrast for renal opacification.
    • A specific needle and catheter insertion technique is employed to access the renal collecting system.
    • Angiographic guides and dilators are used to create and facilitate catheter placement for drainage.

    Main Results:

    • The described technique allows for the insertion of a nephrostomy catheter for prolonged drainage.
    • The prone oblique positioning facilitates safe access to the kidney, avoiding the hilum.
    • The procedure utilizes standard angiographic equipment for tract dilation and catheter insertion.

    Conclusions:

    • Percutaneous nephrostomy using angiographic catheters provides effective temporary urinary drainage.
    • The described technique offers a reliable method for managing upper urinary tract obstruction.
    • Potential complications and technical challenges associated with the procedure are discussed.
