Renal calculi are solid crystals that form in the kidneys and cause severe pain and discomfort. This study aims to investigate risk factors for postoperative recurrence of renal calculi in elderly patients and provide background knowledge on the prevalence and management of renal calculi in this demographic.
The clinical data of 123 elderly patients with renal calculi were included from 1 June 2021 to 1 June 2023 for their 6-month follow-up study. The patients were divided into recurrence group and non-recurrence group according to whether they had recurrence after surgery. The general sociological characteristics and disease-related characteristics of the two groups were counted. Logistic regression equation was used to calculate differences, and the influencing factors of postoperative recurrence in elderly patients with kidney stones were obtained. A receiver operating characteristic (ROC) curve was drawn to analyse the value of the factors in predicting postoperative recurrence in patients with kidney stones.
A total of 123 elderly patients with renal calculi were enrolled. The patients were divided according to the presence or absence of stone recurrence into the recurrence group (25 cases, 20.33%) and the non-recurrence group (98 cases, 79.67%). Postoperative water intake, excessive intake of animal protein, exercise and postoperative complications significantly differed between the recurrence group and the non-recurrence group (p < 0.001). Logistic regression analysis showed that the above-mentioned indicators were the influencing factors of postoperative recurrence. The area under the curve (AUC) values of postoperative water intake (AUC = 0.767), animal protein intake (AUC = 0.752), exercise (AUC = 0.707) and postoperative complications (AUC = 0.727) were statistically significant, and they were identified as the most important factors with high sensitivity and specificity and were of high value in predicting postoperative recurrence of renal calculi.
Elderly patients with kidney stones are prone to recurrence after surgery. Influencing factors should be given attention, and corresponding measures should be formulated for intervention as soon as possible.
