Urinary bowel stone: calculus formation in a repurposed small intestine - a case report.
Article in BMC nephrology, 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
backgroundUrinary diversion with an ileal conduit is associated with an increased risk of urinary tract calculi, driven by metabolic disturbances, recurrent infections, urinary stasis, and foreign bodies. Although stone formation is a known complication, calculi developing around migrated surgical material remain infrequently reported. CASE PRESENTATION: An 81-year-old male patient with a history of radical cystectomy and ileal conduit formation for invasive urothelial carcinoma presented with flank pain and urinary tract infection four years after surgery. Morphological analysis of two spontaneously expelled urinary stones retrieved from the conduit drainage bag classified both calculi as type IVc, with a central nucleus composed of surgical staples. Fourier-transform infrared spectroscopy revealed a mixed composition of struvite (80%) and sodium hydrogenurate (20%), consistent with infection-related lithiasis. The findings supported stone formation around migrated foreign material in the context of chronic bacteriuria.
conclusionSurgical staple migration can act as a nidus for infection-related stone formation in patients with ileal conduits, even several years after cystectomy. Stone analysis plays a crucial role in identifying foreign-body-associated calculi and possible underlying mechanisms. Clinicians should maintain a high index of suspicion for urolithiasis in patients with urinary diversions presenting with flank pain or recurrent infections. CLINICAL
