Immediate versus delayed urinary catheter removal following non-hysterectomy benign gynaecological laparoscopy: a randomised trial.

OBJECTIVE

To compare rates of urinary retention and postoperative urinary tract infection between women with immediate versus women with delayed removal of indwelling catheter following benign non-hysterectomy gynaecological laparoscopic surgery.

DESIGN

This randomised clinical trial was conducted between February 2012 and December 2019, with follow-up to 6 weeks.

SETTING

Two university-affiliated teaching hospitals in Sydney, Australia.

POPULATION: Study participants were 693 women aged 18 years or over, undergoing non-hysterectomy laparoscopy for benign gynaecological conditions, excluding pelvic floor or concomitant bowel surgery.

METHODS

Three hundred and fifty-five participants were randomised to immediate removal of urinary catheter and 338 participants were randomised to delayed removal of urinary catheter.

MAIN OUTCOME MEASURES: The co-primary outcomes were urinary retention and urinary tract infection. Secondary outcomes included hospital readmission, analgesia requirements, duration of hospitalisation and validated bladder function questionnaires.

RESULTS

Urinary retention was higher after immediate compared with delayed removal of the urinary catheter (8.2% vs 4.2%, RR 1.8, 95% CI 1.0-3.0, p = 0.04). Although urinary tract infection was 7.2% following delayed removal of the urinary catheter and 4.7% following immediate removal of the urinary catheter, the difference was not statistically significant (RR 0.7, 95% CI 0.3-1.2, p = 0.2).

CONCLUSIONS

There is an increased risk of urinary retention with the immediate compared with the delayed removal of the urinary catheter following benign non-hysterectomy gynaecological laparoscopic surgery. The difference in urinary tract infection was not significant. There is 1/12 risk of re-catheterisation after immediate urinary catheter removal. It is important to ensure that patients report normal voiding and emptying prior to discharge, to reduce the need for readmission for the management of urinary retention.
