    This study introduces an improved percutaneous nephropyrostomy technique using a fine needle and wider cannula for atraumatic renal access. The method achieved a 93% success rate, replacing traditional operative nephrostomy.

    Area of Science:

    • Urology
    • Nephrology
    • Minimally Invasive Surgery

    Background:

    • Percutaneous nephropyrostomy is a key procedure for urinary tract drainage.
    • Traditional methods can be associated with complications during renal access.
    • There is a need for improved techniques for safer and more effective renal access.

    Purpose of the Study:

    • To describe and evaluate an improved technique for percutaneous nephropyrostomy.
    • To assess the efficacy and safety of a novel needle-cannula system for renal access.
    • To compare the new method with existing operative nephrostomy procedures.

    Main Methods:

    • A modified technique utilizing a long, fine, flexible needle and a wider, shorter cannula was developed.
    • The needle allows for atraumatic puncture of the renal collecting system and antegrade pyelography.

  • The needle then acts as a guide for the insertion of the nephrostomy cannula.

    • Main Results:

    • The improved technique was successful in 105 out of 115 procedures (93% success rate).
    • The study included 93 patients over a 15-month period.
    • The technique demonstrated a high success rate and reliability in clinical practice.

    Conclusions:

    • The described method offers an improved approach to percutaneous nephropyrostomy.
    • This technique facilitates atraumatic renal access and antegrade pyelography.
    • The procedure has been successfully adopted, replacing operative nephrostomy at the authors' institution.
