Sutherland RS, Kogan BA, Baskin LS, Mevorach RA (1996) Clean intermittent catheterization in boys using the LoFric catheter
Evidence of significantly less hematuria with LoFric compared to uncoated plastic catheter with added lubricant. For example, 9 episodes of hematuria were detected in 6 subjects who used LoFric and 19 episodes were detected in 11 subjects in the control group after 2 months use.
2 months study on 16 LoFric users and 14 PVC catheter users.
Vaidyanathan S, Soni BM, Dundas S, Krishnan KR (1994) Urethral cytology in spinal cord injury patients performing intermittent catheterisation
Evidence of LoFric causing less urethral inflammation and presence of bacteria than PVC and urethral indwelling catheters. The study shows a more than 10-fold increase in urethral inflammatory response with PVC catheters compared with LoFric.
Study on 17 LoFric, 14 PVC and 11 indwelling catheter users.
