Infectious complications associated with percutaneous nephrostomy catheters: do we know enough?

Area of Science:

• Nephrology
• Infectious Diseases
• Urology

Background:

• Percutaneous nephrostomy catheters (PCNCs) have transitioned from temporary to permanent solutions for obstructed renal drainage in patients with incurable illnesses.
• Research on PCNC-related infectious complications is often oversimplified, primarily focusing on sepsis without standardized definitions.
• Despite a low overall infection rate, PCNCs present unique challenges in managing associated infections.

Purpose of the Study:

• To review the pathogenesis and treatment of various subtypes of percutaneous nephrostomy catheter-associated infections.
• To emphasize the limitations of current research and the need for standardized definitions in PCNC-related infectious complications.
• To provide a comprehensive overview of infectious complications associated with PCNCs.

Main Methods:

• Literature review of studies on percutaneous nephrostomy catheter-associated infections.
• Analysis of existing research regarding the pathogenesis and treatment of PCNC-related infections.
• Discussion of the challenges in studying the low incidence of infectious complications.

Main Results:

• Percutaneous nephrostomy catheter infections are diverse, extending beyond sepsis.
• Current research lacks standardized definitions for classifying PCNC-associated infectious complications.
• The low incidence of PCNC infections necessitates large sample sizes for robust research.

Conclusions:

• Standardized definitions and criteria are essential for accurate assessment and research of PCNC-associated infections.
• Further research is required to understand the full spectrum of PCNC-related infectious complications and develop targeted interventions.
• Effective management of PCNCs requires a nuanced approach to prevent and treat associated infections.
