Recommendations for how to minimize the rates of these UTIs include the following: Restricting the use of urethral catheterization to indications that are clearly medically necessary (eg, not solely to minimize the number of bedside visits by health care providers made to empty urinals) Removing catheters as soon as possible Using strictly aseptic technique during catheter insertion Maintaining sterility and closure of the drainage system Suprapubic catheterization Suprapubic catheterization via percutaneous cystostomy is done by a urologist or another experienced physician.
