PMID 34329541WHAT IT FOUND
Immediate catheter removal after lobectomy did not increase urinary retention compared with standard removal, but it was associated with fewer urinary tract infections and shorter hospital stay.
Key findings
01Among 177 analysed patients (90 immediate, 87 standard) randomised to immediate removal or removal 48 hours after surgery, urinary retention was 12.2% after immediate removal and 10.3% after standard removal, with no significant difference.
02Catheter-associated urinary tract infection was 6.7% after immediate removal and 17.2% after standard removal.
03Hospital stay was shorter after immediate removal: 6.51 days (range 4 to 11) versus 7.20 days (range 5 to 12).

What it does not show
The trial was single-centre and open-label, so care teams knew which catheter timing was used. The text and table report different percentages for urinary retention and urinary tract infection, so the exact event rates are unclear. Many recruited patients were excluded, including people with benign prostatic hyperplasia, neurogenic bladder, long-term catheter use, complicated surgery, or reoperation. Urinary retention was not significantly different, so the trial does not show that immediate removal reduces retention.
The easy way to misread this
Do not conclude that immediate catheter removal prevents urinary retention or is safe for all surgical patients. The urinary retention outcome was not significantly different, and the trial excluded patients with benign prostatic hyperplasia, neurogenic bladder, long-term catheter use, complicated surgery, and reoperation.
