改良球囊扩张和传统球囊扩张建立经皮肾通道治疗无积水肾结石的比较

Comparative study between improved and traditional balloon dilatation in establishing percutaneous renal channels for treatment of renal calculus patients with non-dilated collecting system

目的:探讨超声引导下改良球囊扩张法建立无积水肾皮肾通道的安全性和有效性,并与传统球囊扩张法比较。方法:收集2017年3月—2021年3月就诊于郑州大学第一附属医院泌尿外科无积水肾结石患者的临床资料,对行改良球囊扩张法及传统球囊扩张法建立皮肾通道患者的临床资料进行倾向性匹配及回顾性分析。结果:倾向性评分匹配后,共有80例(40对)患者纳入研究,其中改良球囊扩张组40例和传统球囊扩张组40例,2组患者的临床资料一致性较好。改良球囊扩张组建立通道一次性成功率高于传统球囊扩张组(97.5%vs.80.0%),差异有统计学意义(P<0.05)。改良球囊扩张组结石清除率高于传统球囊扩张组(85.0%vs.75.0%),但差异无统计学意义(P>0.05)。改良球囊扩张组术中建立通道的时间较传统球囊扩张组术长[(8.0±1.4)min vs.(6.3±1.8)min],差异有统计学意义(P<0.05);但改良球囊扩张组的总体手术时间较传统球囊扩张组更短[(68.7±9.8)min vs.(73.6±12.0)min],差异有统计学意义(P<0.05)。2组患者在出血量、输血率及术后并发症等方面比较差异无统计学意义。结论:改良球囊扩张组建立经皮肾镜通道治疗无积水肾结石患者,可显著提高一次建立通道成功率,缩短总体手术时间。改良球囊扩张建立经皮肾通道方法精准可靠,能明显提高手术安全性。

Objective:To compare the efficacy and security between improved balloon dilatation and conventional balloon dilatation for channel establishment in percutaneous nephrolithotomy(PCNL)for renal calculus patients with non-dilated collecting system.Methods:Clinical data of renal calculus patients with non-dilated collecting system in the department of urology of First Affiliated Hospital of Zhengzhou University from March 2017to March 2021were collected,and propensity matching analysis and retrospective analysis of the clinical data of patients with improved balloon dilatation method and traditional balloon dilatation method were conducted.Results:Eighty pairs of patients were enrolled in the study after propensity score matching.The clinical data of the two groups of patients were well balanced.The success rates of access at the first time of two groups were 97.5%and 80.0%(P<0.05),respectively.The stone clearance rates were 85.0%and 75.0%(P>0.05),respectively.The average time of establishing the renal access of two groups were(8.0±1.4)min and(6.3±1.8)min(P<0.05),but the overall surgical time of two groups were(68.7±9.8)min and(73.6±12.0)min(P<0.05).Additionally,there was no difference in terms of incidence of complications or incidence of blood transfusion between the two groups.The difference was not statistically significant in blood loss(P>0.05).Conclusion:The establishment of percutaneous nephroscopy channel for renal calculus patients with non-dilated collecting system can significantly improve the success rate at the first time channel establishment and shorten the overall surgical time.The impoved balloon dilatation is accurate and reliable,which can significantly improve the surgical safety.
