Urodynamic outcomes and prognostic determinants following endovascular treatment of spinal dural arteriovenous fistulas.
Article in Brain & spine, 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: The prognosis of untreated spinal dural arteriovenous fistulas (SDAVFs) is unfavorable. Current outcome scales used to assess the effect of surgery or endovascular treatment (EVT) rely largely on patient-reported symptoms and may underestimate actual impairment. Moreover, prognostic factors remain debated and conclusions in the literature are inconsistent. Research question: The aim was to quantify urological outcomes after SDAVF embolization using specialized urodynamic testing, compare these objective findings with subjective outcomes derived from traditional scales, and identify prognostic factors associated with unfavorable clinical results. Methods: In this single-center retrospective study, all patients underwent EVT as first-line therapy. Clinical status was assessed using Aminoff-Logue scale (ALS), compared with preoperative data, and correlated with angiographic findings. Urodynamic testing was performed to objectively evaluate bladder function. Results: Twent-four patients met the inclusion criteria. Urodynamic testing was performed in 14 (58 %) patients. The most frequent abnormal finding was bladder hyposensitivity (79 %), followed by pathological post-void residual volume (64 %) and elevated bladder capacity (50 %). Six (43 %) patients reported no subjective urological symptoms (ALS = 0); urodynamic testing revealed two or more pathological parameters in all of them. EVT failure and subsequent surgery predicted gait deterioration (p = 0.011) as well as detrusor overactivity (p = 0.001). Symptom duration over one year (p = 0.038) and fistula location above the T9 level (p = 0.021) were negative prognostic factors for bladder function. Conclusion: The results suggest a potential underestimation of urological impairment when relying on subjective scales and highlight the need for standardized urodynamic testing. They also emphasize the importance of early treatment of SDAVF.
