Laparoscopic and robotic management of symptomatic calyceal diverticula: a systematic review on behalf of YAU and EAU endourology.
Synthesis in World journal of urology, 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
introductionCalyceal diverticula (CD) are outpouchings of the pelvicalyceal system into the renal parenchyma. The purpose of this systematic review is to summarize the outcomes associated with laparoscopic and robotic-assisted approaches for the management of symptomatic CD. MATERIALS AND
methodsOur findings were structured according to the PRISMA statement. We queried three electronic databases, PubMed, Cochrane Library, and Web of Science, to systematically review the literature. Relying on the March 2009 guidelines from the Oxford Centre for Evidence-Based Medicine, two authors independently judged the quality and evidence level of the final articles.
resultsNine studies were included in final qualitative synthesis. The operative time ranged from 80 to 172 (107-197) minutes, while Estimated Blood Loss ranged from 40 (5-100) to 150 (50-300) ml. The Grade I-II complications according to Clavien-Dindo Classification System ranged from 0% to 66.7%, while no Grade III-IV complications were reported in either of the nine studies. The rate of patients reporting flank pain recurrence during the follow-up period ranged from 0% to 28.5%, while recurrence of the diverticulum ranged from 0% to 33.3%. None of the patients with flank pain or diverticulum recurrence needed a reoperation.
conclusionsThe findings of this systematic review suggest that laparoscopic and robotic approaches are feasible and have shown favorable outcomes in selected patients with symptomatic CD, particularly in cases with complex anatomy or after failed endourological treatment. However, the available evidence remains limited.
