Retrograde intrarenal surgery is advancing with new technologies, expanding treatment for kidney stones and other conditions. Urologists must adapt to these changes while managing potential laser and ureteral injuries.
Area of Science:
- Urology
- Endourology
- Nephrology
Background:
- Technological advancements have increased the popularity and applications of retrograde intrarenal surgery.
- New laser systems and miniaturized ureteroscopes have expanded treatment indications beyond kidney stones.
Purpose of the Study:
- To review the evolution and current state of retrograde intrarenal surgery.
- To discuss clinical options and future trends in endourology.
Main Methods:
- Literature review of technological advancements in endourology.
- Analysis of expanded indications for retrograde intrarenal surgery.
- Discussion of potential complications and management strategies.
Main Results:
- Retrograde intrarenal surgery now treats larger renal stones (>2 cm), upper tract urothelial carcinoma, ureteral strictures, and idiopathic renal hematuria.
- New technologies enable broader applications but necessitate awareness of risks.
Conclusions:
- Clinicians must integrate new endourologic technologies effectively.
- Managing risks like thermal injury, ureteral damage, and radiation exposure is crucial for safe and successful retrograde intrarenal surgery.
