[The forgotten urinary catheter]. / 5 minutes pour apprendre - La sonde urinaire que l'on traîne à retirer.

Catheter-associated urinary tract infections (CAUTI) are the most common type of healthcare-associated infection. They have a major impact on morbi-mortality and costs. Approximately 25 % of inpatients receive urinary catheters during their hospital stay. The most important risk factor for CAUTI is prolonged use of the catheter, and its appropriate use is on the Top Five list of the Choosing wisely campaign for the inpatient sector in Switzerland. Through the report of this clinical case, we review the guidelines for the appropriate use of urinary catheters, with a particular focus on reducing the risk of recurrent acute urinary retention after catheter ablation in men with benign prostatic hyperplasia.
