What is urethral stricture?
Urethral stricture is a narrowing of the urethra that can cause urinary obstruction.
Why use a buccal mucosa graft?
Buccal mucosa grafts are used for their favorable healing properties and compatibility with urethral tissue.
How is the stricture induced in the model?
Stricture is induced surgically in Wistar rats to mimic clinical conditions.
What assessments are performed post-surgery?
Retrograde urethrogram and laser Doppler assessments are performed to evaluate the outcomes.
What are the implications of this study?
The study provides a foundation for developing new therapies for urethral stricture.
Is this model applicable for human studies?
While it is an animal model, it can inform future clinical research and trials.
