The Screw Dilator (Threaded Ureteral Dilator) is a unique endourological device featuring a continuous helical thread along its distal working end. By converting rotational torque into controlled forward axial motion, it allows urologists to advance through tough, fibrous urethral or ureteral strictures that resist direct axial pushing.

The Filiform Dilator (with accompanying follower catheter) is a specialized urological dilating instrument designed to navigate complex, tortuous, or pinpoint urethral strictures that resist standard catheterization. The initial ultra-thin, highly flexible filiform tip leads through the stricture, after which a larger follower dilator is threaded onto its base to safely dilate the tract.
The Stone Basket is an essential endourological accessory used during retrograde intrarenal surgery (RIRS) and ureteroscopy to capture, manipulate, and extract urinary tract stones. Available in various wire counts and tip designs, it provides a secure cage for transporting stone fragments out of the urinary tract.
The Metal Telescopic Dilator (Alken Dilator Set) is a classical, highly rigid endourological access system used to establish percutaneous nephrostomy tracts during PCNL. Consisting of a central guide rod and a series of stainless steel tubes that nest over one another, it provides high mechanical force to dilate dense scar tissue and thick flank muscle.
