Summary
The Steffens lasso loop offers easier ureteral stone passage and better stone grasping. This instrument achieved an 85.7% immediate extraction rate in distal ureteral stones, proving valuable in endourology.
Area of Science:
- Urology
- Endourology
- Surgical Instrumentation
Background:
- Distal ureteral stones present a significant clinical challenge.
- Effective and minimally invasive extraction methods are crucial for patient outcomes.
Purpose of the Study:
- To evaluate the efficacy and safety of the Steffens lasso loop for distal ureteral stone extraction.
- To assess the instrument's advantages over existing endourological techniques.
Main Methods:
- The Steffens lasso loop was utilized in 560 patients with distal ureteral stones between 1976 and 1986.
- Data collected included stone extraction rates, ureteral perforation incidence, and need for ureterolithotomy.
Main Results:
- Immediate stone extraction was achieved in 85.7% of patients treated in 1986.
- Ureteral perforation occurred in 2.3% of cases.
- 3% of patients required ureterolithotomy.
Conclusions:
- The Steffens lasso loop is an effective and valuable instrument for distal ureteral stone management.
- Its design facilitates less traumatic passage and improved stone grasping.
- It represents a significant addition to the endourological armamentarium.
