Summary
Endoscopic surgery, including percutaneous stone removal, is highly successful for upper urinary tract stones, largely replacing open procedures. While complications are rare, vigilance for issues like AV malformations is necessary.
Area of Science:
- Urology
- Minimally Invasive Surgery
Background:
- Endoscopic surgery for upper urinary tract stones has advanced significantly.
- Open surgical procedures are now rarely used for stone removal.
Purpose of the Study:
- To evaluate the efficacy and outcomes of endoscopic stone removal techniques.
- To assess the success rates and complications associated with percutaneous and transurethral stone removal.
Main Methods:
- Over 1,000 cases of percutaneous stone removal were analyzed.
- Transurethral uretero-renoscopy instruments were utilized for ureteral stones.
Main Results:
- Success rates for renal and uretero-pelvic junction stones were 96%.
- Success rates for ureteral stones were approximately 86%.
- Complications, including AV malformations, were rare and manageable.
Conclusions:
- Endoscopic techniques, particularly percutaneous stone removal, are highly effective for upper urinary tract stones.
- These minimally invasive methods offer high success rates with manageable complications.
- Endoscopic approaches are also valuable for diagnosing and treating uretero-pelvic junction obstruction.
