4A Nottingham One-Step Dilator

SKU: 4A-UR-0018

The Nottingham One-Step Dilator is a tapered single-step catheter designed for rapid dilation of the ureteral orifice and intramural ureter prior to rigid ureteroscopy or stent placement. Engineered for swift progression over a guidewire, it eliminates the need for sequential dilation sets in routine endourological interventions.

Key Benefits

  • Single-Pass Dilation: Rapidly dilates the ureterovesical junction (UVJ) in one motion, saving surgical time during URS procedures.
  • Graduated Long Taper: Smooth tip-to-shaft transition minimizes force required to cross tight ureteral orifices.
  • Radiopaque Shaft Construction: Provides continuous X-ray visibility during positioning near the ureteric meatus.
  • Kink-Resistant Shaft: Maintains pushability without buckling in the bladder cavity.
  • Guidewire Lock Compatibility: Standard inner lumen slides smoothly over 0.035 in or 0.038 in endourology wires.
