ABSTRACT=<sec><title>Aim</title><p>To assess the effect of preoperative blood glucose (POBG) levels on the length of stay (LOS) in patients with kidney stones undergoing percutaneous nephrolithotomy (PCNL).</p></sec><sec><title>Methods</title><p>We conducted a retrospective study of patients who underwent PCNL at the Zhongda Hospital of Southeast University from 2013 to 2019. The relationship between POBG level and LOS was investigated by dose-response analysis curves of restricted cubic spline function.</p></sec><sec><title>Results</title><p>We included 310 patients and divided them into three groups (&lt;5.04, 5.04 to &lt;6.88, ≥6.88 mmol/L) according to the POBG levels. Patients with POBG levels ≥6.88 mmol/L (adjusted odds risk [aOR] 1.67; 95% CI 0.83–3.33) had a 67% higher risk of LOS &gt; 2 weeks than patients with POBG levels &lt;5.04 mmol/L. A positive dose-response analysis curve was observed between POBG and the adjusted risk of LOS &gt;2 weeks. Similar results were observed in the subgroups analysis.</p></sec><sec><title>Conclusion</title><p>We demonstrated that higher POBG levels were significantly associated with longer LOS in patients with kidney stones undergoing PCNL.</p></sec>
