Do you meet patients who experience discomfort during catheter removal?
Every catheterisation causes strain on the urethra. The problem is not only acute one-off damages to the urethra, but the fact that over time these micro-traumas might add up and become a real complication, such as a urinary tract infection and/or a stricture. Most complications occur after 5 years of CIC1.

Catheter with low osmolality
This catheter has a coating with an osmolality lower than urine. What will happen? In nature’s strive for balance, the water molecules will leave the catheter surface and move towards the urethra. This may cause the catheter to dry out and friction to increase upon removal.
Catheter with high osmolality
This is a catheter with a high osmolality. The surface is isotonic to urine, which means it has the same concentration of salt as the body/urethra itself. The water molecules will remain in place, ensuring that the catheter’s low friction is maintained throughout the whole catheterisation procedure.
