Recent advances in percutaneous nephrolithotomy (PNL) enhance its efficacy and safety for renal stones. Innovations in imaging, patient positioning, endoscopic combined intrarenal surgery (ECIRS), lithotripsy, and tube management are improving outcomes.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Nephrolithotomy
Background:
- Percutaneous nephrolithotomy (PNL) remains a primary treatment for renal stones.
- Continuous advancements aim to improve PNL's effectiveness and patient safety.
Purpose of the Study:
- To analyze recent innovations in percutaneous nephrolithotomy (PNL) techniques.
- To highlight advancements contributing to improved efficacy and safety in renal stone management.
Main Methods:
- Review of recent literature on percutaneous nephrolithotomy (PNL) innovations.
- Identification of key progressing areas in PNL technique and management.
Main Results:
- Key advancements include improved imaging (CT scans), evolving patient positioning (supine vs. prone), endoscopic combined intrarenal surgery (ECIRS), enhanced intracorporeal lithotripsy devices, and novel post-PNL tube management (tubeless/nephrostomy-free procedures).
- These innovations aim to optimize the percutaneous nephrolithotomy (PNL) procedure.
Conclusions:
- Urologists are actively refining percutaneous nephrolithotomy (PNL) to increase stone-free rates and reduce morbidity.
- Further large-scale trials are necessary to validate the benefits and drawbacks of these PNL innovations.
