Summary
The new Radiofocus guide wire successfully enabled ureteric catheterization in all 24 patients, including difficult cases. This new guide wire is a valuable tool for extracorporeal shock-wave lithotripsy (ESWL) and other urologic procedures.
Area of Science:
- Urology
- Medical Devices
Background:
- Conventional guide wires can fail during ureteric catheterization, particularly after extracorporeal shock-wave lithotripsy (ESWL).
- Difficulties arise from prior indwelling stent use, post-ESWL stone formation, or ureteric stenosis.
Purpose of the Study:
- To evaluate the efficacy of the new Radiofocus guide wire for ureteric catheterization in challenging cases.
- To assess the utility of the Radiofocus guide wire in various urologic interventions.
Main Methods:
- The Radiofocus guide wire was used for ureteric catheterization in 24 subjects.
- Subjects included patients with prior ESWL, stone streets, ureteric stenosis, and those with previously unsuccessful catheterization attempts.
Main Results:
- Successful insertion of the Radiofocus guide wire into the renal pelvis was achieved in all 24 cases.
- An indwelling catheter was successfully passed in 21 out of 24 cases.
- The guide wire facilitated catheterization in patients with prior ESWL, stone streets, and ureteric stenosis.
Conclusions:
- The Radiofocus guide wire is effective for ureteric catheterization, especially in cases where conventional methods fail.
- This guide wire offers a valuable solution for extracorporeal shock-wave lithotripsy (ESWL) therapy.
- Potential applications include retrograde pyelography, managing ureteric obstruction, and dilating ureteric stenosis.
