Objective To investigate the characteristics of urolithiasis and the composition of stones in patients treated at Dandong Central Hospital, and to provide a scientific basis for the prevention and treatment of urolithiasis.Methods Clinical data were collected from 800 patients with urinary stones treated at Dandong Central Hospital from September 2019 to December 2023.Stone composition analysis, combined with gender, age, stone location and other related factors were performed for comparative analysis.Results The incidence rate was higher in males, with a male-to-female ration of 1.82︰1.Upper urinary tract stones were more common (88.75%).There were more male patients than female patients in the age group of 21-30 (P<0.05).The incidence of upper urinary tract stones was higher in patients aged 31-50 and those over 61 than that of lower urinary tract stones (P<0.01).Among the stone components, calcium oxalate monohydrate had the highest detection rate (71.38%).There were 214 cases (26.75%) of single-component stones, including 74 cases (9.25%) of calcium oxalate monohydrate and 60 cases (7.50%) of anhydrous uric acid, which were more common in male patients and the upper urinary tract.Mixed stones were found in 586 cases (73.25%), with calcium oxalate monohydrate + calcium oxalate dihydrate being the most common combination (324 cases, 40.50%), and they occurred more frequently in the upper urinary tract than in the lower urinary tract (P<0.001).In addition, stone types of calcium oxalate monohydrate + carbonate apatite and calcium oxalate dihydrate + anhydrous uric acid were also more common in the upper urinary tract (P<0.05).Conclusion There are differences in gender, age and stone location among patients with urinary calculi in Dandong region.Calcium oxalate is the predominant component, with mixed stones being more common.Understanding the composition of urinary stones in Dandong is of great significance for the prevention and treatment of urolithiasis in this region.
