目的

比较输尿管软镜碎石术(FURL)与微通道经皮肾镜碎石取石术(mPCNL)治疗单侧直径<2.0 cm 肾和输尿管上段结石的成本-效果。

方法

收集2022 年3 月至11 月江苏省人民医院收治的115 例单侧直径<2.0 cm 肾和输尿管上段结石患者的数据,采用Treeage Pro 软件构建结石术后1 个月的决策树分析模型,评估两种碎石手术方式的临床疗效、安全性和经济性。并通过单因素敏感性分析、概率敏感性分析对本研究结果的稳健性进行验证。

结果

FURL 组的首次碎石成功率显著高于mPCNL 组,差异有统计学意义(P<0.05),两组患者在术后并发症发生情况方面差异无统计学意义(P>0.05)。基础分析结果显示,FURL 组成本和健康效用分别为29 080.9 元和0.90 质量调整生命年(QALYs),mPCNL 组的成本和健康效用分别为26 787.6 元和0.87 QALYs,FURL 相较于mPCNL 的增量成本-效果比(ICER)为76 443.3 元/QALYs,低于意愿支付值阈(WTP)257 100 元/QALYs,因此FURL 组为优势方案。当患者的支付意愿价格高于60 000 元时,FURL 组具有经济性的概率高于mPCNL 组,敏感性分析结果验证了基础分析结果的稳健性。

结论

FURL 治疗肾和输尿管上段结石能有效缩短手术时间,增加结石清除率,在术后并发症方面与mPCNL 无差异,且成本-效果优势显著,具有良好的临床价值和卫生经济学优势。

Objective

To compare the cost-effectiveness of flexible ureteroscopic lithotripsy(FURL) versus mini-percutaneous nephroscopic lithotripsy (mPCNL) for treating unilateral renal and upper ureteral stones with diameter <2.0 cm.

Methods

The data of 115 patients with unilateral kidney diameter <2.0 cm and upper ureteral calculi admitted in Jiangsu Province Hospital from March to November 2022 were collected, and the decision tree analysis model analyzing outcomes one month after surgery was constructed using Treeage Pro software to evaluate the clinical efficacy,safety and economy of the two lithotripsy procedures.The robustness of the results of this study was verified by one-way sensitivity analysis and probabilistic sensitivity analysis.

Results

The success rate of first lithotripsy in FURL group was significantly higher than that in mPCNL group,with a significant difference (P<0.05), and no significant difference in the occurrence of postoperative complications in the two groups (P>0.05).The basic analysis showed that the FURL cost and health utility were 29 080.9 and 0.90 quality adjusted life years (QALYs), respectively, the cost and health utility of mPCNL group were 26 787.6 and 0.87 QALYs, respectively, the incremental costeffectiveness ratio (ICER) of mPCNL was 76 443.3/QALYs, which was lower than willingness to pay(WTP), so FURL group was the dominant scheme.When the patient's willingness to pay is higher than 60 000 yuan, the FURL group has a higher probability of economy than the mPCNL group, and the sensitivity analysis results verify the robustness of the basic analysis results.

Conclusion

FURL treatment of renal and upper ureteral stones can effectively shorten the operation time and increase the stone clearance rate, which has no significant difference from mPCNL in terms of complications, and has significant cost-effect advantages, with good clinical value and health economic advantages.
