Minimally invasive percutaneous nephrolithotomy (PCNL): Techniques and outcomes

Area of Science:

• Urology
• Minimally Invasive Surgery

Background:

• Standard percutaneous nephrolithotomy (sPCNL) has associated morbidity.
• Minimally invasive percutaneous nephrolithotomy (mPCNL) techniques were developed to reduce this morbidity.
• Mini-PCNL includes micro-PCNL and ultra-mini-PCNL (UMP).

Purpose of the Study:

• To review and compare different mini-PCNL techniques.
• To discuss the advantages and disadvantages of each mPCNL approach.
• To evaluate the current literature on mPCNL.

Main Methods:

• Comprehensive literature review.
• Critical analysis of retrieved articles on PCNL modifications.
• Synthesis of data on mini-PCNL techniques.

Main Results:

• Mini-PCNL techniques aim to decrease morbidity associated with sPCNL.
• Key advantages of mPCNL include less peri-operative bleeding and shorter hospital stays.
• No mPCNL technique has yet replaced sPCNL, but indications are expanding.

Conclusions:

• Mini-PCNL offers significant benefits over sPCNL, including reduced bleeding and shorter hospital stays.
• While generally safe, micro-PCNL and UMP warrant cautious use.
• Further research and refinement of mPCNL techniques are ongoing.
