Current evidence on intermittent catheterization: sterile single-use catheters or clean reused catheters and the incidence of UTI.

Intermittent catheterization is a commonly prescribed procedure for people with incomplete bladder emptying not managed by other methods. The most frequent complication of intermittent catheterization is urinary tract infection (UTI). It is unclear what strategies, including sterile vs clean catheters or coated vs uncoated PVC catheters, affect the incidence of UTIs. This systematic review summarizes current evidence on the relationship between sterile single-use catheters or clean reused catheters and the incidence of UTIs.
