Hygiene management of intermittent self-catheterization using reusable silicone catheters in people with spinal cord lesions: A cross-sectional Internet survey in Japan.

Objectives: To investigate hygiene management and catheter maintenance of reusable silicone catheters for intermittent self-catheterization (ISC) in Japan and examine their relationship with symptomatic urinary tract infection (sUTI).
Methods: We conducted a cross-sectional Internet survey of people performing ISC using reusable silicone catheters owing to spinal cord lesions in Japan. Hygiene management and catheter maintenance of reusable silicone catheters and the incidence and frequency of sUTI were evaluated. We also examined the significant risk factors for sUTI.
Results: Of 136 respondents, 62 (46%), 41 (30%), and 58 (43%) washed hands with water, washed hands with soap, and cleaned or disinfected the urethral meatus every time or most of the time before ISC, respectively. No significant difference was observed in the incidence and frequency of sUTI between respondents who adhered to these procedures and those who did not. There were no significant differences in the incidence and frequency of sUTI in respondents who changed their catheters every month and in those who changed their preservation solution within 2 days compared with those who did not. In multivariate analysis, pain during ISC, inconvenience of indoor mobility, bowel management problems, and participants' feeling of never having received instruction on catheter replacement were significant risk factors for sUTI.
Conclusions: There are individual differences in hygiene management and catheter maintenance of reusable silicone catheters, but the influence of these differences on the incidence and frequency of sUTI is not clear. Pain during ISC, bowel management problems, and inadequate instruction on catheter maintenance procedures are factors associated with sUTI.
