Intermittent catheterization is the preferred method of bladder management likely due to a reduced incidence of renal impairment, reflux, stone disease, bladder cancer and possibly UTI compared to other methods of bladder management (Groah et al. 2002; Weld & Dmochowski 2000; Ord et al. 2003). The first section (18.104.22.168) outlines those studies focusing on specific aspects of IC including timing of catheterization, effectiveness, long-term follow-up, and QoL. The second section (22.214.171.124) outlines studies examining catheter types.
