Percutaneous nephrostomy (PN) effectively treats pyonephrotic kidneys, rapidly relieving symptoms in most patients. This minimally invasive procedure often serves as a crucial step before definitive treatments like further interventions or surgery.

Area of Science:

  • Urology
  • Nephrology
  • Interventional Radiology

Background:

  • Pyonephrosis, a severe kidney infection with obstruction, poses significant clinical challenges.
  • Prompt management is crucial to prevent sepsis and preserve renal function.
  • Percutaneous nephrostomy (PN) is a potential intervention for relieving obstruction and draining infected urine.

Purpose of the Study:

  • To evaluate the efficacy and role of percutaneous nephrostomy (PN) in managing pyonephrotic kidneys.
  • To assess the contribution of PN as a primary or adjunctive treatment modality.

Main Methods:

  • Retrospective analysis of 76 pyonephrotic kidneys in 73 patients treated with percutaneous nephrostomy (PN) tubes.
  • Evaluation of clinical outcomes, including symptom resolution, need for further procedures, and complications.

  • Documentation of definitive treatment pathways following initial PN.

    • Main Results:

    • Clinical symptoms resolved within 24-48 hours in 71 patients post-PN.
    • PN facilitated definitive therapy in 36 of 39 cases requiring intervention, with 32 proceeding to elective surgery.
    • Six cases of sepsis were managed successfully; two patients with anuria and malignancy did not survive.

    Conclusions:

    • Percutaneous nephrostomy (PN) is a safe and effective initial treatment for pyonephrosis, rapidly improving clinical status.
    • PN serves as a vital bridge to definitive treatment, whether interventional or surgical, in most cases.
    • The procedure demonstrates a favorable safety profile with manageable complications.
