Authors' conclusion
The findings of this cohort study suggest that 1 in 17 male patients, 1 in 11 male patients aged 65 years or older, and 1 in 34 female patients may develop POUR following IHR.
Study context
- Population
- Adults undergoing elective inguinal hernia repair (open or minimally invasive; local, neuraxial or GA), 209 centres in 32 countries, March–October 2021
- Participants
- 4,151 adults · 209 centres · 32 countries
- Exposure
- Male vs Female
- Malen = 3,882
- Femalen = 269
- Outcome
- Incidence of POUR following elective inguinal hernia repair (IHR)

Main finding
As reported in the abstract
Incidence of POUR
Observational data: associations, not effects.
Secondary outcomes
| Outcome | Values |
|---|---|
| Incidence of POUR (male patients aged ≥65 y, subgroup) | Male ≥65 y 9.5% |
- Incidence of postoperative urinary retention (POUR) (male patients aged ≥65 y, subgroup): 119 of 1252
Risk factors for POUR (adjusted analyses)
- Increasing age, anticholinergic medication, history of urinary retention, constipation, out-of-hours surgery, bladder within the hernia, temporary intraoperative urethral catheterisation, increasing operative duration
Health service outcomes: POUR as primary reason
- Unplanned day-case surgery admissions due to POUR (n = 74)
- 27.8%
- 30-day readmissions due to POUR (n = 72)
- 51.8%
