Prevention of Recurrence in Elderly Patients with Kidney Stone by Using the Knowledge-Attitude-Practice Education Model: A Single-Centre, Retrospective Study.

Background: Kidney stones are common in elderly patients, and their high recurrence rate after surgery is a significant clinical issue. This single-centre retrospective study aimed to assess the impact of the knowledge-attitude-practice (KAP) education model on preventing kidney stone recurrence in elderly patients.

Methods: Elderly patients who underwent kidney stone surgery from January 2022 to January 2023 were divided into an intervention group and a control group based on the KAP education model intervention. The recurrence of stones, renal function, calcium and phosphorus metabolism, and urine indices were compared before and 3 months after treatment in the two groups.

Results: The recurrence rates of kidney stones in the intervention group at 6 months, 1 year and 2 years after the surgery were all lower than the control group (p < 0.05). The levels of serum creatinine, blood urea nitrogen, uric acid and cystatin C in both groups 3 months after the intervention were lower than those before the treatment, and the reduction of each renal function index in the intervention group was more significant (p < 0.05). The total 24-hour urine volume in both groups was higher than before treatment, while urinary calcium, urinary oxalate and urinary uric acid (UA) were lower. The improvement of each urine index was more obvious in the intervention group (p < 0.05).

Conclusions: The KAP education model has a significant effect on preventing the recurrence of kidney stones in elderly patients.
