urethral dilation
Gradual stretching of the urethra using progressively larger instruments to treat strictures.
Full Definition
Urethral dilation is a procedure used to treat urethral strictures by gradually stretching the narrowed area with metal sounds, balloon dilators, or other graduated instruments. This technique aims to restore normal urethral caliber and improve urinary flow. While historically common, urethral dilation has limitations including temporary results and potential for trauma or worsening of strictures. Modern urologic practice often favors more definitive treatments like urethroplasty for complex or recurrent strictures, though dilation may still be appropriate for select cases.
Usage
Usage note: Often considered a temporizing measure rather than definitive treatment for urethral strictures.
