Incidence of Urinary Tract Infection After Combined Cystoscopy and Urodynamic Testing: A Prospective Cohort Study.
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
objectiveTo evaluate the incidence of urinary tract infection (UTI) after combined cystoscopy and urodynamic testing.
methodsA prospective analytical cohort study was conducted including adult patients undergoing cystoscopy, urodynamic testing, or both procedures during the same session at a quaternary referral center between May 1, 2023, and April 30, 2024. All patients were managed under an institution-wide, urine culture-guided antibiotic prophylaxis protocol. The cumulative incidence of UTI within 30 days after the procedure was calculated for the three cohorts. Sociodemographic characteristics, urodynamic parameters, and cystoscopic findings were analyzed to assess their association with UTI occurrence.
resultsA total of 560 patients were included, of whom 473 (84.5%) completed follow-up. Women accounted for 39.7% and men for 60.3% of the cohort, with a median age of 69 years. Seventeen patients underwent combined cystoscopy and urodynamic testing, 194 underwent urodynamic testing alone, and 262 underwent cystoscopy alone. No UTIs were observed in the combined cohort. The incidence of UTI was 2.6% following urodynamic testing and 1.9% following cystoscopy alone. No significant associations were identified between patient characteristics, urodynamic variables, or cystoscopic findings and the development of UTI.
conclusionsCombined cystoscopy and urodynamic testing do not appear to increase the risk of UTI compared with either procedure performed separately. Larger studies are required to confirm these findings and to define optimal antibiotic prophylaxis strategies and identify high-risk subgroups.
