This study was conducted across 209 centers in 32 countries in a consecutive sample of adult patients undergoing elective IHR.<\/jats:p><\/jats:sec>Exposure<\/jats:title>Open or minimally invasive IHR by any surgical technique, under local, neuraxial regional, or general anesthesia.<\/jats:p><\/jats:sec>Main Outcomes and Measures<\/jats:title>The primary outcome was the incidence of POUR following elective IHR. Secondary outcomes were perioperative risk factors, management, clinical consequences, and health service outcomes of POUR. A preoperative International Prostate Symptom Score was measured in male patients.<\/jats:p><\/jats:sec>Results<\/jats:title>In total, 4151 patients (3882 male and 269 female; median [IQR] age, 56 [43-68] years) were studied. Inguinal hernia repair was commenced via an open surgical approach in 82.2% of patients (n\u2009=\u20093414) and minimally invasive surgery in 17.8% (n\u2009=\u2009737). The primary form of anesthesia was general in 40.9% of patients (n\u2009=\u20091696), neuraxial regional in 45.8% (n\u2009=\u20091902), and local in 10.7% (n\u2009=\u2009446). Postoperative urinary retention occurred in 5.8% of male patients (n\u2009=\u2009224), 2.97% of female patients (n\u2009=\u20098), and 9.5% (119 of 1252) of male patients aged 65 years or older. Risk factors for POUR after adjusted analyses included increasing age, anticholinergic medication, history of urinary retention, constipation, out-of-hours surgery, involvement of urinary bladder within the hernia, temporary intraoperative urethral catheterization, and increasing operative duration. Postoperative urinary retention was the primary reason for 27.8% of unplanned day-case surgery admissions (n\u2009=\u200974) and 51.8% of 30-day readmissions (n\u2009=\u200972).<\/jats:p><\/jats:sec>Conclusions<\/jats:title>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. These findings could inform preoperative patient counseling. In addition, awareness of modifiable risk factors may help to identify patients at increased risk of POUR who may benefit from perioperative risk mitigation
