ObjectiveTo establish the recurrence risk model after minimally invasive surgery for kidney stones to analyze the influencing factors of recurrence related to health behavior in patients with kidney stones from Fuyang Second People's Hospital for providing the evidence-based strategies in clinical nursing intervention.

MethodsThe data of disease at first onset and recurrence after minimally invasive surgery related to disease in 148 kidney stones patients treated with minimally invasive surgery were retrospectively analyzed.The health behavior ability of pateints after the first minimally invasive surgery for calculi were assessed using the health behavior ability self-rating scale.The calculus recurrence model was established by univariate analysis and multivariate logistic regression analysis.

ResultsThe number of hypertensive and diabetic patients in recurrent group were higher than that in non-recurrent group, and the proportion of patients with body mass index(BMI) > 30.0 kg/m² in recurrence group was higher than that in non-recurrence group(P < 0.05 to P < 0.01).The differences of the daily intake of water, nature of regular drinking water, frequent use of fish oil, frequent consumption of preserved foods and intake of protein sources between two groups were statistically significant(P < 0.05 to P < 0.01).The total score of healthy behavior ability, and scores of nutritional dimension, psychological comfort dimension and health responsibility dimension in non-recurrent group were higher than those in recurrent group(P < 0.05).The model recurrence equation was LogitP=6.122-0.633X₁₍₁₎-2.512X₁₍₂₎+1.351X₂-4.124X₃-1.888X₄-2.111X₅-0.996X₆.The results showed that the 1.5-3 L/d water intake, healthy behavior ability, frequent use of fish oil, intake mainly plant protein were the protective factors of stone recurrence, and the water intake less than 0.5 L/d, BMI > 30.0 kg/m² and frequent consumption of preserved food were the risk factors of stone recurrence.According to the coefficient of the equation, the proportion from large to small were healthy behavior ability, daily water intake, pickled food, BMI and protein source in turn.

ConclusionsTo prevent recurrence of kidney stones after operation, the nursing intervention should focus on improving patients' healthy behavior ability and forming healthy lifestyle.
