Performing percutaneous nephrolithotomy (PCNL) in the supine position is a safe and effective alternative to the prone position. This technique offers benefits for both patients and urologists, enhancing stone manipulation in the upper urinary tract.
Area of Science:
- Urology
- Nephrolithotomy
- Surgical Positioning
Background:
- Percutaneous nephrolithotomy (PCNL) traditionally uses the prone position.
- The supine position was adopted in 1998, demonstrating safety and efficacy.
Purpose of the Study:
- To report experience with PCNL in the supine position.
- To detail the technique for supine PCNL.
Main Methods:
- 62 patients (67 renoureteral units) were treated in the supine position.
- Technique modifications were made for Chinese patients.
Main Results:
- Primary stone clearance rate was 76%.
- Mean PCNL sessions: 1.3.
- No major procedure-related complications or splanchnic injuries.
Conclusions:
- Supine PCNL offers advantages in patient and urologist comfort and stone manipulation.
- Limitations are manageable, making supine PCNL a viable alternative to prone PCNL.
