Beyond Joint Hypermobility: Investigating Bladder Dysfunction in Hypermobile Ehlers-Danlos Syndrome.
Article in Neurourology and urodynamics, 2026. 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
INTRODUCTION AND
objectivesHypermobile Ehlers-Danlos Syndrome (hEDS) is the most common subtype of Ehlers-Danlos Syndrome, a group of connective tissue disorders caused by collagen abnormalities. While musculoskeletal features of hEDS are well characterized, its impact on visceral organs, including the bladder, remains underexplored. Despite frequent patient reports of urinary symptoms, a definitive link between hEDS and bladder pathology has not been established. This study aims to characterize lower urinary tract symptoms (LUTS) and urodynamic (UDS) findings in patients with hEDS to better understand potential mechanisms underlying bladder dysfunction in this population. MATERIALS AND
methodsA retrospective chart review was conducted on patients with hEDS who underwent video UDS at a single tertiary-care center between 2022 and 2025. Inclusion criteria included age > 18, confirmed hEDS diagnosis (2017 criteria), and completed UDS. Data were analyzed using Welch's t-test and Fisher's Exact Test.
resultsAmong 27 patients, the mean age at hEDS diagnosis was 30.9 years (range 18-49), 92.6% (n = 25) were female, and 92.6% (n = 25) were white. Common LUTS seen in these patients included frequency in 74.1% (n = 20), incontinence in 14.8% (n = 4), frequent urinary tract infections in 25.9% (n = 7), bladder pain in 33.3% (n = 9), nocturia in 48.1% (n = 13), and weak stream in 51.8% (n = 14) of patients. UDS findings revealed no evidence of detrusor overactivity, stress urinary incontinence, or abnormalities in compliance. 1 patient had incomplete emptying with a pre-study post-void residual of 500 mL. Pelvic floor dysfunction was seen in 18.5% (n = 5) with active EMG noted during emptying. Pelvic floor physical therapy was the most common intervention recommended, followed by beta-3 agonists for overactive bladder symptoms.
conclusionsOur findings demonstrate that LUTS are prevalent in patients with hEDS, with evidence pointing to pelvic floor and neurologic dysfunction as key contributors rather than intrinsic bladder pathology. These results support prioritizing a pelvic floor-focused approach to evaluation and management of hEDS-related LUTS.
