    Summary

    Ultrasound-guided percutaneous nephrostomy (PNS) is a safe and effective procedure for various kidney conditions. This minimally invasive technique, using the Malecot nephrostomy set, showed no major complications in 72 patients.

    Area of Science:

    • Urology
    • Interventional Radiology

    Context:

    • Percutaneous nephrostomy (PNS) is a crucial intervention for managing diverse renal pathologies.
    • The Malecot nephrostomy set offers a standardized approach for tract dilation and catheter placement.
    • Ultrasound guidance enhances precision and safety during percutaneous renal access.

    Purpose:

    • To evaluate the safety and efficacy of ultrasound-guided percutaneous nephrostomy (PNS) using the Malecot nephrostomy set.
    • To assess PNS outcomes in patients requiring treatment for post-renal anuria, hydronephrosis, urinary leakage, vesical bleeding, and as pretreatment for percutaneous nephro-uretero lithotomy (PNL).

    Summary:

    • The study involved 72 patients (80 kidneys) undergoing ultrasound-guided PNS.
    • Different Malecot or Bardex catheters were used based on the indication, with specific sizes for PNL pretreatment.

  • While minor complications like fever and potential renal injury were noted, no major adverse events occurred, and blood transfusions were not required.

    • Impact:

    • Percutaneous nephrostomy using the Malecot nephrostomy set demonstrates a favorable safety profile.
    • This technique provides an effective minimally invasive option for managing complex urological conditions.
    • The findings support the routine use of ultrasound-guided PNS in clinical practice for selected patients.
