Fluoroscopically guided percutaneous extraction of upper urinary tract calculi
Radiologic Clinics of North America
|June 1, 1984
Summary
Percutaneous manipulations now treat over 90% of upper urinary tract stones. Fluoroscopic guidance allows direct extraction of two-thirds of these renal and ureteral calculi.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Medical Instrumentation
Background:
- Management of renal and ureteral calculi has been significantly advanced by new instrumentation.
- Percutaneous techniques are now the standard for treating most upper urinary tract stones.
Purpose of the Study:
- To describe techniques and equipment for fluoroscopically guided percutaneous extraction of renal and ureteral calculi.
- To highlight the advancements in managing kidney and ureteral stones.
Main Methods:
- Percutaneous manipulations for upper urinary tract calculi.
- Fluoroscopic guidance for stone extraction.
- Nephroscopic control for stone disintegration using ultrasonic or electrohydraulic energies.
Main Results:
- Over 90% of upper urinary tract calculi can be managed percutaneously.
- Approximately two-thirds of stones are extracted under fluoroscopic or nephroscopic control.
- Remaining stones are disintegrated using ultrasonic or electrohydraulic energies.
Conclusions:
- Fluoroscopically guided percutaneous extraction is a highly effective method for treating renal and ureteral calculi.
- Modern instrumentation has revolutionized the treatment of upper urinary tract stones, enabling high success rates with minimally invasive approaches.
