Proposition for new terminologies in PCNL: what does 'ultra-mini-micro' actually mean?

Area of Science:

• Urology
• Minimally Invasive Surgery

Background:

• Percutaneous nephrolithotomy (PCNL) techniques are continually miniaturized.
• Access sheaths as small as 4.8Fr are now utilized in adult PCNL procedures.
• The proliferation of terms like "micro," "mini," and "ultra" creates ambiguity in PCNL descriptions.

Purpose of the Study:

• To propose a straightforward classification system for PCNL.
• To standardize the terminology used for miniaturized PCNL techniques.
• To encompass both technological and procedural advancements in PCNL.

Main Methods:

• Review of current miniaturized PCNL techniques and terminology.
• Development of a proposed classification system based on sheath size and technology.
• Analysis of how the proposed system addresses existing terminology confusion.

Main Results:

• A simple, standardized classification system for PCNL terminology is proposed.
• The system aims to clarify the distinctions between various "miniaturized" PCNL approaches.
• It provides a framework to categorize advancements in PCNL technology and procedures.

Conclusions:

• Standardized terminology is crucial for clear communication in miniaturized PCNL.
• The proposed classification system offers a solution to the current terminological ambiguity.
• Adoption of this system will facilitate better understanding and reporting of PCNL advancements.
