末端可弯负压吸引鞘输尿管软镜碎石取石技术在肾结石中的应用

Application of Distally Deflectable Negative Pressure Suction Sheath-Assisted Flexible Ureteroscopic Lithotripsy and Stone Extraction Technique in Renal Calculi

摘要: 目的：探究末端可弯负压吸引鞘输尿管软镜碎石取石技术在治疗肾结石上的疗效和安全性。方法：选择2024年3月1日至2025年3月1日在安徽医科大学第四附属医院泌尿外科收治的100名肾结石患者，根据手术方法将患者分为对照组和观察组，其中对照组采用传统输尿管软镜碎石技术，观察组采用末端可弯负压吸引鞘输尿管软镜碎石取石技术，比较两组患者的手术时间、结石尺寸、结石清除率、术后住院时间、术后感染发生率等情况。结果：两组患者的手术时间、结石尺寸、术后住院时间大致相同，差异无统计学意义(P > 0.05)。观察组的即时和4周后结石清除率均高于对照组，差异有统计学意义(P < 0.05)。观察组的术后感染率低于对照组，差异有统计学意义(P < 0.05)。结论：末端可弯负压吸引鞘输尿管软镜碎石取石技术在治疗肾结石上具有更高的结石清除率，术后感染的发生率更低，对于肾结石的治疗和预后更有利。

Abstract: Objective: To explore the efficacy and safety of flexible negative pressure suction sheath ureterlithotripsy in the treatment of kidney stones. Methods: choose on March 1, 2024 to March 1, 2025 in the Fourth Affiliated Hospital of Anhui Medical University urology admitted 100 kidney stone patients, according to the operation method will be divided into the control group and observation group, the control group using the traditional ureteral lithotripsy technique, the observation group can end curved negative pressure suction sheath flexible lithotripsy technique, compare the two operation time of patients, stone size, stone clearance, postoperative hospital stay, postoperative infection incidence, etc. Results: The operation time, stone size, and postoperative hospitalization time were roughly the same in the two groups, and there was no statistically significant difference (P > 0.05). The stone clearance rate in the observation group was higher than that of the control group, which was significant (P < 0.05). The postoperative infection rate in the observation group was lower than the control group, which was significant (P < 0.05). Conclusion: The terminal bending negative pressure suction sheath ureteral lithotripsy technique has higher stone clearance rate and lower incidence of postoperative infection, which is more favorable for the treatment and prognosis of kidney stones.
