Summary
This study introduces an improved method for creating accurate nephrostomy tracts during percutaneous nephrolithotomy (PCNL) for large kidney stones. The new technique enhances safety, reduces complications, and offers a learnable approach for PCNL procedures.
Area of Science:
- Urology
- Minimally Invasive Surgery
Background:
- Percutaneous Nephrolithotomy (PCNL) is the standard treatment for large kidney stones.
- Accurate nephrostomy tract creation is crucial for successful PCNL outcomes.
Purpose of the Study:
- To describe and evaluate a novel method for establishing an accurate nephrostomy tract during PCNL.
- To assess the safety and effectiveness of this improved PCNL procedure.
Main Methods:
- Retrospective single-center study of 937 patients undergoing PCNL with the new technique.
- Preoperative B-ultrasonography and CT scan for precise puncture point determination.
- Real-time intraoperative B-ultrasound guidance for tract creation.
Main Results:
- The study included 937 patients, with 851 having renal stones and 86 ureteropelvic junction stones.
- Patient distribution across Guy's grading system: Grade I (0%), II (42.69%), III (51.01%), IV (6.30%).
- Average patient age was 48.49 ± 10.80 years; male to female ratio was 1.73:1.
Conclusions:
- The developed method ensures accurate and safe PCNL by optimizing nephrostomy tract establishment.
- Advantages include minimal radiation, fewer complications, and low failure rates.
- This approach is highly suitable for institutions new to PCNL due to its safety, efficacy, and learnability.
