Perioperative cognitive dysfunction in bladder cancer patients, causal factors, and possible interventions.
Review in Frontiers in medicine, 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
Bladder cancer (BC) primarily necessitates surgical and oncological interventions; however, patients frequently encounter a substantial burden of perioperative neurocognitive disorders, which compromise clinical outcomes and treatment compliance. While individual risks are recognized, a comprehensive synthesis identifying the overlapping clinical determinants and promoters of this decline remains essential. This review aims to elucidate the specific mechanisms underlying perioperative cognitive impairment in surgical BC patients and highlight targeted preventive strategies. Evidence demonstrates that perioperative cognitive decline in this population is highly multifactorial. Key demographic and clinical predictors include advanced age and clinical frailty, which are compounded by chronic cerebral small vessel disease secondary to long-term tobacco smoking, hypertension, and metabolic diseases. Furthermore, surgical and procedural risks, such as frequent instrumentation and catheterization, are associated with bleeding and a higher incidence of recurrent urinary tract infections, which induce systemic inflammation and may precipitate acute disorientation or delirium. Anesthesia-related factors, including preoperative benzodiazepine use, intraoperative hypotension, prolonged anesthesia duration, and the omission of neuromuscular blockade reversal agents, significantly exacerbate post-surgical cognitive vulnerability. All these factors, with systemic inflammation, may cause cerebral hypoperfusion that precipitates delirium. Metabolic comorbidities, particularly diabetes mellitus, synergistically exacerbate infection risks, while psychological distress (severe anxiety and depression) and neurotoxic chemotherapy protocols serve as vital indicators of post-surgical cognitive vulnerability. Cognitive function heavily dictates urological care trajectories. Incorporating routine, structured preoperative cognitive and frailty screenings is imperative to risk-stratify patients, implement tailored pre-habilitation, and optimize both cognitive and oncological outcomes.
