Outcomes and management of de novo ureteral strictures following ureteroscopy: A retrospective observational study.
Observational study in Urologia, 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
introductionUreteral strictures are a recognised late complication post ureteroscopy (URS). Most research on the pathology focuses on mechanisms of injury and preventative strategies. There is limited data describing follow up patterns and treatment outcomes. The aim was to evaluate the subsequent management and outcomes of de novo ureteral strictures post URS.
methodsRetrospective review was conducted of patients diagnosed with a de novo ureteral stricture post URS at a tertiary centre between 2014 and 2024. Eligible cases were identified by manual review of ICD-coded records (N13.0-N13.5), yielding 40 patients for analysis. Baseline and procedural data were summarised descriptively, and group comparisons were performed using the Mann-Whitney U and Fisher's exact tests.
resultsAmong 40 patients (median age 69 years), most strictures were detected symptomatically (67.5%) and were located proximally or distally (each 43%). Median time to diagnosis was 3.8 months, and median follow-up was 4.3 years. Overall, 45% achieved successful resolution after a median of two procedures, while 15% underwent nephrectomy. Higher age-adjusted Charlson Comorbidity Index scores and older age were significantly associated with poorer outcomes, although interpretation is limited by the sample size. Stricture length and a history of stone impaction showed no significant associations.
conclusionsIn this cohort, fewer than half of patients with de novo ureteral strictures following URS achieved lasting resolution despite multiple interventions. These findings highlight the potential clinical burden of this complication and support the importance of preventive strategies, timely detection and structured follow-up, while underscoring the need for further studies to better define long-term outcomes.
