Summary
A novel hydrophilic Glidewire technique offers a safe and effective alternative to traditional filiforms and followers for managing urethral obstruction, demonstrating high success rates with no complications.
Area of Science:
- Urology
- Medical Devices
Background:
- Urethral obstruction presents a significant clinical challenge.
- Traditional methods like filiforms and followers can be traumatic and may fail.
- A less invasive and equally effective alternative is needed.
Purpose of the Study:
- To introduce and evaluate a novel technique for managing urethral obstruction.
- To assess the efficacy and safety of using a hydrophilic Glidewire as an alternative to filiforms and followers.
Main Methods:
- The Glidewire is passed per urethra, similar to a filiform.
- Intravesical placement is confirmed with a ureteral catheter.
- The Glidewire is exchanged for a Teflon-coated guidewire for subsequent dilation or catheter placement.
Main Results:
- The Glidewire technique achieved a 95% success rate (19 out of 20 attempts).
- This method was effective even after failed attempts with filiform catheters.
- Successful treatment of urethral obstruction due to strictures, bladder neck contractures, and benign prostatic hyperplasia was observed.
Conclusions:
- The Glidewire method provides a safe and effective approach for most urethral obstruction cases.
- This technique is recommended over standard filiforms and followers when cystourethroscopy is unavailable.
