Threaded (screw-type) shaft for slow, controlled expansion
Made from stainless steel
Offers mechanical advantage with minimal trauma
Often used with guidance from a filiform
Uses:
Gradual dilation of tight urethral strictures, especially where standard dilators may not pass
Used in urology for difficult or complex urethral stricture cases
Helps avoid the need for immediate surgery
