Application of the modified prone limb-split lithotomy position in complex urinary tract stone surgery
泌尿外科改良俯卧分腿截石位在复杂尿路结石手术中的应用

摘要

目的 探析泌尿外科复杂尿路结石手术中运用改良俯卧分腿截石位的价值。方法 取我院（时间：2025年5月~2025年11月）复杂尿路结石患者86例，纳入标准：通过影像学检查（B超、CT等），复杂尿路结石确诊；与手术治疗指征相符；18岁~75岁；无手术禁忌。排除标准：泌尿系统伴先天性畸形；摆放手术体位难以配合者。86例纳入者均行手术治疗，随机分组，对照组43例+分腿俯卧位，观察组43例+改良俯卧分腿截石位，分析组间效用。结果 观察组手术指标均较对照组更优，术中、术后观察组HR（心率）、DBP（舒张压）、SBP（收缩压）较对照组更佳（P<0.05）。组间结石清除率（P>0.05）。结论 复杂尿路结石手术选择改良俯卧分腿截石位取得了显著效用，利于手术指标提高，血流动力学稳定，可行。

Abstract

Objective To explore the value of using modified prone split-leg lithotomy in surgery for complex urinary tract stones in urology.
Methods A total of 86 patients with complex urinary tract stones were included from our hospital (time period: May 2025 to November 2025). Inclusion criteria: confirmed through imaging examinations (B-ultrasound, CT, etc.), diagnosed with complex urinary tract stones; met surgical treatment criteria; aged 18 to 75 years; no contraindications for surgery. Exclusion criteria: congenital malformations of the urinary system; patients who could not cooperate with the surgical position. All 86 included patients underwent surgical treatment, randomly divided into a control group of 43 cases + split-leg prone position and an observation group of 43 cases + modified prone split-leg lithotomy, analyzing the effectiveness between the two groups.
Results The surgical indicators in the observation group were significantly better than those in the control group. During and after surgery, the HR (heart rate), DBP (diastolic blood pressure), and SBP (systolic blood pressure) in the observation group were better than those in the control group (P<0.05). The stone clearance rate between the groups was not significant (P>0.05).
Conclusion   Using the modified prone split-leg lithotomy in surgery for complex urinary tract stones has shown significant effectiveness, improving surgical indicators and stabilizing hemodynamics, making it feasible.
