LoFric Catheters Leave Nothing Behind

The Importance of Complete Bladder Emptying

Complete bladder emptying is known to prevent urinary tract infections (UTIs). Residual urine can contain bacterial sediment, mucus and uric acid crystals. If left in the bladder, these particles can grow over time and cause UTIs or bladder stones.

Who is at risk of developing bladder stones?

There are some patient groups that experience an increased risk for problems related to incomplete bladder emptying:

  • Stone formation is the second most prevalent urinary tract complication for individuals with spinal cord injury.(1) 
  • Multiple Sclerosis patients have a 3.5 times higher risk of developing urinary tract stones.(2) 
  • Men with Benign Prostatic Enlargement (BPE) have an 8 times higher bladder stone frequency than men without BPE.(3)

Why is the size of catheter holes important?

There are many different types of intermittent catheters on the market. In the below table we have listed some of the most common ones and how they compare.

*Sediment in urine from intermittent catheter users is often larger than 0.13 mm2 (5)

During the 20 years I have been working as a nurse in the continence field I can assure that most people performing intermittent catheterization has some kind of particles in their urine, it’s proteins, blood, salt, mucous and other particles. It depends on many factors, like type of food and amount of fluid intake. One thing is clear, urine from intermittent catheter users is not clear as apple juice!
