Effect of intraoperative urinary catheter use on postoperative urinary retention after laparoscopic inguinal hernia repair. A randomized clinical trial.

JAMA Surg 2022; 157: 667-674.

Routine use of a urinary catheter did not reduce the risk of postoperative retention in this study that included 491 procedures: 9.6 versus 8.5 per cent, P=0.79.

Comment: It’s time to stop using a catheter routinely in those who can void urine spontaneously preoperatively.
