In acute urinary retention with an indwelling catheter, after how long is a trial of spontaneous voiding typically attempted to balance chance of voiding with the risk of catheter-associated infection?

In acute urinary retention with an indwelling catheter, after how long is a trial of spontaneous voiding typically attempted to balance chance of voiding with the risk of catheter-associated infection?

• A. 24-48 hours
• B. 48-72 hours
• C. 72-96 hours
• D. 96 hours or more

Answer: (B)

When a patient has acute urinary retention relieved with a catheter, the bladder needs time to recover coordinated detrusor contraction after overdistension. Trying to void too soon often fails because the detrusor has not regained strength, leading to persistent retention or the need to reinsert a catheter. Waiting a short while allows this recovery while avoiding keeping the catheter in place longer than necessary. The balance is that keeping the catheter longer raises the risk of catheter-associated infections, urethral irritation, and discomfort, so the window is kept short but sufficient for recovery. Typically, a trial of spontaneous voiding is attempted about 2 to 3 days after catheter placement, with removal if the patient voids with an acceptable residual and without obstruction. If voiding fails, re-catheterization or alternative management is pursued and the evaluation for underlying causes continues.
