Incidence and risk factors for postoperative urinary retention in older patients with hip fracture: a scoping review.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThis scoping review aimed to synthesise the currently available evidence and influencing factors on the occurrence of postoperative urinary retention (POUR) in older patients with hip fractures.
designThis scoping review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guideline. DATA SOURCES: PubMed, Cochrane Library, CINAHL, Web of Science, Chinese National Knowledge Infrastructure, Wanfang Data and Sinomed databases were systematically searched from database inception to 1 September 2024. ELIGIBILITY CRITERIA: We included observational studies reporting on POUR prevalence and risk factors among patients aged 60 years and older with hip fractures and excluded systematic and non-systematic reviews, conference proceedings, editorials, commentaries, qualitative studies and case studies. Duplicated articles and articles unable to access the full text were also excluded. We also excluded studies with populations with pathologic fractures, multiple fractures, treated for periprosthetic fracture, or if studies were published in a language other than English and Chinese. DATA EXTRACTION AND SYNTHESIS: Two authors independently extracted and summarised the data. We summarised the prevalence and risk factors for POUR in older patients with hip fractures.
resultsA total of 106 studies were identified, and 12 studies (all from published literature sources) detailing POUR prevalence and risk factors were included. The studies showed that the incidence of POUR in older patients with hip fractures ranged from 11.10% to 51.33%, and the risk factors included impaired activities of daily living, use of anticholinergic medications, serological indicators (serum albumin and thyroid-stimulating hormone), complications (urinary infection and postoperative incontinence), prolonged indwelling urinary catheters and faecal impaction. In addition, male sex, cognitive impairment, use of opioid medications and coexisting diabetes may also be risk factors for POUR, which still needs to be further clarified
conclusionThe incidence of POUR in older patients with hip fractures varies widely. Most factors were reported in one study with no proposed underlying mechanism for their influence. Further high-quality studies are needed to validate these findings.
