Utilising the Seldinger catheter introduction system to place the custom designed cystometry (urodynamic) catheter offers a number of advantages to both the clinician and the patient:

• Minimum trauma for the patient
• Minimum tissue damage
• Locating the bladder with the 18g hypodermic needle confirms correct location for catheter introduction
• The 70%/30% split lumen configuration ensures a faster filling rate, and better pressure measurement using the smallest charriere size
• Colour-coded pressure lines enable easy identification
