Summary
Navigating difficult ureters is simplified by using a floppy wire followed by a stiff wire via a ureteral catheter. This technique offers a high success rate for ureteral access and stent placement.
Area of Science:
- Urology
- Medical Devices
- Minimally Invasive Surgery
Background:
- Negotiating tortuous or obstructed ureters with guidewires can be challenging and time-consuming.
- Existing methods may lead to prolonged procedures and increased patient/clinician fatigue.
Purpose of the Study:
- To present an effective technique for navigating difficult ureteral passages.
- To improve the success rate and efficiency of ureteral access for stent placement.
Main Methods:
- Utilizing a slippery floppy guidewire initially to navigate the ureter.
- Replacing the floppy wire with a stiff guidewire through a 5-French open-ended ureteral catheter.
- Employing the ureteral catheter for radiocontrast studies and guidewire access.
Main Results:
- The described technique achieves a high success rate in navigating challenging ureteral anatomy.
- The method facilitates efficient access for placing 0.035-inch coaxial guidewires.
- The ureteral catheter enables subsequent placement of single or double J stents.
Conclusions:
- This two-wire technique, utilizing a ureteral catheter, is a highly successful approach for managing tortuous or obstructed ureters.
- It streamlines the process of ureteral access and stent insertion, improving procedural outcomes.
