Uretero-enteric stricture outcomes: secondary analysis of a randomised controlled trial comparing open versus robot-assisted radical cystectomy.
Trial report in BJU international, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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
objectivesTo analyse the risk of uretero-enteric anastomotic stricture in patients randomised to open (ORC) or robot-assisted radical cystectomy (RARC) with extracorporeal urinary diversion. PATIENTS AND
methodsWe included 118 patients randomised to RARC (n = 60) or ORC (n = 58) at a single, high-volume institution from March 2010 to April 2013. Urinary diversion was performed by experienced open surgeons. Stricture was defined as non-malignant obstruction on imaging, corroborated by clinical status, and requiring procedural intervention. The risk of stricture within 1 year was compared between groups using Fisher's exact test.
resultsIn all, 58 and 60 patients were randomised to RARC and ORC, respectively. We identified five strictures, all in the ORC group. In patients with ≥1 year of follow-up, the increase in risk of stricture from open surgery was 9.3% (95% confidence interval 1.5%, 17%). Of the five strictures, three were managed endoscopically while two required open revision. There was no evidence that perioperative Grade 3-5 complications were associated with development of a stricture (P = 1) and no evidence of a difference in 24-month estimated glomerular filtration rate between arms (P = 0.15).
conclusionsIn this study at a high-volume centre, RARC with extracorporeal urinary diversion achieved excellent ureteric anastomotic outcomes. Purported increased risk of stricture is not a reason to avoid RARC. Future research should examine the impact of different surgical techniques and operator experience on the risk of stricture, especially as more intracorporeal diversions are performed.
