Summary
This study shows a new endoscopic technique using a guide wire and hollow dilators successfully treated 90% of patients with pinhole urethral strictures. This minimally invasive method offers a practical alternative to optical urethrotomy.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Endourology
Background:
- Urethral strictures, particularly pinhole types, pose significant clinical challenges.
- Traditional treatments like optical urethrotomy can be invasive and may not always be available.
Purpose of the Study:
- To evaluate the efficacy and safety of a novel endoscopic dilation technique for pinhole urethral strictures.
- To present a practical alternative to optical urethrotomy.
Main Methods:
- Endoscopic introduction of a flexible guide wire through the stricture.
- Passage of flexible hollow dilators over the guide wire to widen the narrowed segment.
- Treatment applied to ten patients with pinhole urethral strictures.
Main Results:
- Successful treatment in 9 out of 10 patients (90% success rate).
- The procedure demonstrated minimal trauma to the urethral tissue.
- High technical success and patient tolerance observed.
Conclusions:
- Endoscopic dilation using a guide wire and hollow dilators is a highly effective treatment for pinhole urethral strictures.
- This technique offers a minimally invasive and practical alternative to optical urethrotomy.
- Recommended for urological settings lacking optical urethrotomy capabilities.
