 Q Does immediate removal of an indwelling catheter after hysterectomy reduce recatheterisations, complications, and pain more than catheter removal on the first day after surgery?

    METHODS

    Embedded ImageDesign:

    randomised controlled trial.

    Embedded ImageAllocation:

    {concealed}*.

    Embedded ImageBlinding:

    blinded {outcome assessors and data analysts}*.

    Embedded ImageFollow up period:

    24 hours after surgery.

    Embedded ImageSetting:

    a medical centre in Denver, Colorado, USA.

    Embedded ImagePatients:

    250 women (median age 47 y, 63% Hispanic) who had hysterectomy for various benign diseases (eg, fibroid tumours, abnormal uterine bleeding, chronic pain, persistent cervical dysplasia, or microinvasive cervical cancer). Exclusion criterion: anticipated complicated surgical procedures (ie, bladder suspension or colporraphy, diagnosis suspicious for severe endometriosis, or requirement of strict fluid treatment).

    Embedded ImageIntervention:

    immediate removal of the catheter in the operating room (n = 125) or removal of the catheter on postoperative day 1 (n = 125).

    Embedded ImageOutcomes:

    recatheterisation, fever (temperature ⩾38.5°C), symptomatic urinary tract infection, and pain located in the bladder or urethra (assessed using a 10 point, pictorial scale).

    Embedded ImagePatient follow up:

    100%.

    MAIN RESULTS

    Women who had immediate catheter removal in the operating room did not differ from women who had catheter removal on postoperative day 1 for recatheterisation for an additional 24 hours (4.8% v 2.4%, {p = 0.31}*), fever (4% v 4.8%, {p = 0.76}*), or urinary tract infections (2.4% v 2.4%). Fewer women in the immediate removal group reported severe pain (table).

    CONCLUSION

    Immediate removal of an indwelling catheter after hysterectomy did not differ from catheter removal on postoperative day 1 for recatheterisation, fever, or urinary tract infections, but was associated with fewer reports of severe postoperative pain.

    Commentary

    Indwelling urinary catheters are frequently used after urogenital surgery to monitor urine output and to prevent urinary retention. Although there seems to be no clinical uncertainty about the need for an empty bladder before surgery, controversy arises about the ideal time to remove the catheter. Removal of indwelling catheters tends to be based on personal preference and tradition rather than evidence from research.1

    The study by Dunn et al was carefully designed, with appropriate and clinically relevant outcomes. The major findings were that patients who had immediate removal of indwelling catheters had no adverse outcomes and reported significantly less pain than patients who had their catheters removed after 24 hours.

    These findings are particularly relevant to health professionals in gynaecology, but should also raise questions for health professionals working in other surgical services. Urinary catheterisation is not a harmless procedure. Urinary tract infections account for about 40% of hospital acquired infections, and 80% of urinary tract infections acquired in hospital are associated with urinary catheters.2 Such infections not only prolong hospital stay and are expensive to treat but also cause unpleasant symptoms.3 Health professionals are guided in practice by the ethical principle of “doing no harm.” The findings of the study by Dunn et al will support practitioners who want to protect and work in partnership with their patients. Immediate postoperative removal of catheters is likely to restore dignity and control to patients. If catheterisation cannot be avoided, nurses must aim to remove the catheter as soon as possible to alleviate unnecessary pain and other risks to patient safety.
