Comparative Study of Prone Position Variations for Percutaneous Nephrolithotomy.

Area of Science:

• Urology
• Minimally Invasive Surgery
• Nephrolithiasis Management

Background:

• Percutaneous nephrolithotomy (PCNL) is a key procedure for kidney stone removal.
• The optimal patient positioning for PCNL remains a subject of investigation to enhance efficacy and safety.

Purpose of the Study:

• To compare the efficacy and safety of flat-prone versus prone hip flexed PCNL.
• To determine the optimal patient position for percutaneous nephrolithotomy.

Main Methods:

• Retrospective analysis of patients undergoing PCNL in flat-prone or prone hip flexed positions for kidney stones.
• Comparison of demographic data, clinical findings, stone characteristics, operative data, and post-operative outcomes.

Main Results:

• No significant differences in demographic data, stone-free status, or complication rates between the two groups.
• Flat-prone PCNL had a shorter average Operation Room Time (ORT).
• Prone hip flexed PCNL demonstrated significantly shorter durations for nephrostomy and hospitalization.

Conclusions:

• Flat-prone PCNL is associated with a shorter ORT.
• Prone hip flexed PCNL offers advantages in reduced nephrostomy and hospitalization times.
• The study provides insights for selecting the optimal prone PCNL position.
