Urodynamic findings of pediatrics with history of failed anti-vesicoureteral surgery.
Article in American journal of clinical and experimental urology, 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
purposeTo evaluate the role of functional bladder dysfunction in failed vesicoureteral reflux (VUR) surgery through conventional urodynamic study. MATERIALS AND
methodsThis cohort study was conducted at the Labbafinejad Hospital in 2020-2022. Patients <18 years with VUR who were referred with failed surgical intervention (persistence, progression, or recurrence of reflux on the same or opposite side) were included. Demographic information (sex, urinary tract symptoms, type of surgical intervention, and side and grade of VUR) and urodynamic study UDS results were recorded and analyzed statistically.
results53 patients were referred with failed surgery, with an average age of 8.20 ± 3.88 and a male-to-female ratio of 0.76/1.25. Bilateral vesicoureteral reflux (VUR) was present in 47.2%. Detrusor overactivity (DO) and dysfunctional voiding (DV) were found in 41 (77.4%) and 37 (69.8%) patients. The mean maximum amplitude and frequency of DOs were 50.58 ± 43.12 and 9.02 ± 8.15. Patients with bilateral VUR had significantly higher DO (92% vs 64.2%, P = 0.022), DO amplitude (70.60 ± 40.78 vs 32.71 ± 37.43, P = 0.001), and DO frequency (11.52 ± 8.14 vs 6.79 ± 7.63, P = 0.034).
conclusionIndividuals with failed VUR surgery commonly have UDS abnormalities and it is more severe in bilateral VUR patients. It can be postulated that non-surgical management and medications may be recommended as the first approach.
