Stone composition in patients undergoing surgical treatment for kidney stones: a cross-sectional study at a tertiary hospital in Vietnam.
Article in BMC 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
objectiveEvaluate the composition of kidney stones in patients undergoing surgical interventions at Binh Dan Hospital. SUBJECTS AND
methodsPatients undergoing surgical management for renal or ureteral calculi at Binh Dan Hospital between July 2023 and April 2025 were included. Stone composition was determined by infrared spectroscopy and X-ray diffraction.
resultsA total of 765 stone units from 743 patients were analyzed. Percutaneous nephrolithotomy accounted for most procedures (86.01%), followed by retroperitoneal laparoscopic ureterolithotomy (7.32%), semirigid ureterolithotripsy (5.10%), and open surgery (1.57%). The composition of the stones revealed that calcium oxalate stones were the most common at 63.4%, including whewellite (calcium oxalate monohydrate) at 51.9% and weddellite (calcium oxalate dihydrate) at 11.5%. Phosphate stones were the next most common, with dahllite (hydroxyapatite) accounting for 25.49% and brushite accounting for 0.52%. Among infection stones, truvite accounted for 3.4% and ammonium hydrogen urate accounted for 0.26%. Uric acid stones and the rare cystine stones accounted for 5.88% and 1.05%, respectively. The proportion of mixed stones in this study accounted for 58.56%. The combinations containing whewellite predominated, accounting for 86.13%. The combination of whewellite + weddellite + dahllite was the most prevalent, representing 31.76% of the cases.
conclusionCalcium oxalate was the most common stone type. Compared with global data, variations were observed only in selected stone components, suggesting possible regional influences.
