Day surgery is critical for efficient healthcare delivery, but delayed discharge remains a key quality metric. This study investigates perioperative blood index changes during transurethral ureteroscopic laser lithotripsy (TULL) and constructs a risk prediction model for delayed discharge. A retrospective analysis of 526 TULL day surgery patients (2017-2021) compared normal (n = 412) and delayed discharge groups (n = 114). Blood indicators (WBC, Hb, Lymph#, Mono#, Neut#, Eos#) and clinical variables were analyzed. Logistic regression and ROC curves evaluated predictive factors. Delayed discharge was linked to longer operation time (OR = 1.024) and higher urine WBC (OR = 1.001), while Mono# showed protective effects (OR = 0.127). The model achieved an AUC of 0.710 (95% CI: 0.637-0.787), with strong calibration. The model enables early identification of high-risk patients, guiding interventions to reduce delayed discharge and improve day surgery management.
日间手术对于高效的医疗服务提供至关重要，但延迟出院仍是关键的质量指标。本研究调查经尿道输尿管镜激光碎石术（TULL）围手术期血液指标变化，并构建延迟出院风险预测模型。对526例TULL日间手术患者（2017 - 2021年）进行回顾性分析，比较正常出院组（n = 412）和延迟出院组（n = 114）。分析血液指标（白细胞、血红蛋白、淋巴细胞计数、单核细胞计数、中性粒细胞计数、嗜酸性粒细胞计数）和临床变量。采用逻辑回归和ROC曲线评估预测因素。延迟出院与手术时间延长（OR = 1.024）和尿白细胞升高（OR = 1.001）有关，而单核细胞计数显示出保护作用（OR = 0.127）。该模型的AUC为0.710（95%CI：0.637 - 0.787），具有良好的校准度。该模型能够早期识别高危患者，指导干预措施以减少延迟出院并改善日间手术管理。
