Clinical study of metabolic assessment in patients with renal calculi in diet prevention and treatment

Abstract

Objective By analyzing the metabolic assessment of patients with renal calculi, to explore and study the prevention and treatment of rental calculi formation and recurrence through dietary intervention, to provide evidence for clinical practice. Methods 163 patients undergoing minimally invasive lithotomy were collected from October 2016 to October 2017, then the stone specimens were collected and analyzed, and the urine samples were taken to detect the risk factors of 24 h urinary stone formation. They were randomly divided into control group (81 cases) and experimental group (82 cases). The control group had more drinking water without special diet prevention, while the experimental group was given corresponding diet prevention according to the result of the stone composition and the risk factors of 24 h urinary stone formation. The two groups were followed up for six months, to observe the effects on the recurrence rate of renal calculi. Results Among 163 patients with renal calculi, 157 cases completed the study (79 cases in the control group and 78 cases in the experimental group), the shedding rate was 3.68% (6/163). In the control group, there was no statistically significant difference in the analysis of 24 h urine composition before and after prevention (P>0.05); the indexes of urine oxalic acid, uric acid, and urine calcium decreased and the index of urine citric acid increased in the experimental group after prevention, with statistically significant differences (P 0.05). After 6 months of diet prevention, 5 cases of renal calculi recurred in the control group, and the recurrence rate was 6.33% (5/79); there was no recurrence in 78 cases of the experimental group; the recurrence rate of the experimental group was significantly lower than that of the control group, with statistically significant difference (P<0.01). Conclusions Metabolic assessment can detect the potential risk factors that affect the occurrence and recurrence of renal calculi, and individualized preventive measures can be made according to the results of metabolic assessment, which can effectively reduce the recurrence of renal calculi, worthy of clinical application.
