Objective
To evaluate if immediate catheter removal (
ICR
) after laparoscopic hysterectomy is associated with similar retention outcomes compared with delayed removal (
DCR
).
Study design
Non‐inferiority randomised controlled trial.
Population
Women undergoing laparoscopic hysterectomy in six hospitals in the Netherlands.
Methods
Women were randomised to
ICR
or
DCR
(between 18 and 24 hours after surgery).
Primary outcome
The inability to void within 6 hours after catheter removal.
Results
One hundred and fifty‐five women were randomised to
ICR
(
n
= 74) and
DCR
(
n
= 81). The intention‐to‐treat and per‐protocol analysis could not demonstrate the non‐inferiority of
ICR
: ten women with
ICR
could not urinate spontaneously within 6 hours compared with none in the delayed group (risk difference 13.5%, 5.6–24.8,
P
= 0.88). However, seven of these women could void spontaneously within 9 hours without additional intervention. Regarding the secondary outcomes, eight women from the delayed group requested earlier catheter removal because of complaints (9.9%). Three women with
ICR
(4.1%) had a urinary tract infection postoperatively versus eight with
DCR
(9.9%, risk difference −5.8%, −15.1 to 3.5,
P
= 0.215). Women with
ICR
mobilised significantly earlier (5.7 hours, 0.8–23.3 versus 21.0 hours, 1.4–29.9;
P
≤ 0.001).
Conclusion
The non‐inferiority of
ICR
could not be demonstrated in terms of urinary retention 6 hours after procedure. However, 70% of the women with voiding difficulties could void spontaneously within 9 hours after laparoscopic hysterectomy. It is therefore questionable if all observed urinary retention cases were clinically relevant. As a result, the clinical advantages of
ICR
may still outweigh the risk of bladder retention and it should therefore be considered after uncomplicated laparoscopic hysterectomy.
Tweetable abstract
The advantages of immediate catheter removal after laparoscopic hysterectomy seem to outweigh the risk of bladder retention.
