Health Care Utilization and Complications Rates among Users Of Hydrophilic-Coated Catheters
Observational study of catheter associated complications in 288 long-term (mean of 10 years) LoFric users. The results suggest that LoFric use reduces the risk of complications associated with intermittent catheterization and that users may benefit from a change to LoFric.

Physical predictors of infection in patients treated with clean intermittent catheterization: 7-year study
Long term evidence that intermittent catheterization using LoFric reduces the risk for urethral complications, including UTI. For example, 65% UTI-free and 39% with sterile urine after long term LoFric use.
7 year follow up on 155 LoFric patients.

Clean intermittent catheterization in spinal cord injury patients: long-term followup of a hydrophilic low friction technique
Evidence on the long term use of hydrophilic catheters to reduce UTI and prevent urethral trauma. For example, no new urethral trauma was identified during a 5-9 year follow up with LoFric.
5-9 year follow up on 30 LoFric patients.
