不同尺寸双J管在输尿管软镜术后对净石率和双J管综合征的影响

The Effect of Different Size of Double J Tubes on Stone Free Rate and Double J Tube Syndrome after Flexible Ureteroscopy Surgery

摘要: 双J管已经成为临床治疗泌尿系统疾病常用的置入性器械之一，其基本原理为建立人工通道，避开尿路的梗阻部位，缓解输尿管阻塞；同时，对于输尿管镜及输尿管软镜碎石术后患者，置入双J管可促进结石碎片的排出，提高净石率，从而起保护肾功能的作用。可在双J管的应用过程中，与支架留置相关的不良反应也为患者带来了不少的痛苦。因此可见，双J管的置入和支架相关症状之间的相关性是显而易见的。先前关于双J管的相关研究主要集中在支架设计、材料、位置和药物管理方面，但支架尺寸相关研究较少。目前，支架尺寸对双J管相关并发症和净石率的影响尚不清楚。有鉴于此，以比较不同尺寸的双J管引起的支架相关症状及对尿路结石的疗效作一综述。

Abstract: Double J tube has become one of the commonly used implantable instruments in clinical treatment of urinary diseases. Its basic principle is to establish artificial channels to avoid the obstruction of urinary tract and relieve ureteral obstruction. At the same time, for patients after ureteroscopic and flexible ureteroscopic lithotripsy, the placement of double J tube can promote the excretion of stone fragments, improve the stone free rate, and thus protect renal function. But in the application of double J tube, the adverse reactions related to stent retention also brought a lot of pain to pa-tients. Therefore, the correlation between double J tube implantation and stent-related symptoms is obvious. Previous studies on double J tubes are mainly focused on stent design, material, location and drug management, but there are few studies on stent size. At present, the effect of stent size on double J tube related complications and stone free rate is not clear. In view of this, the stent-related symptoms caused by double J tubes of different sizes and the curative effect on urinary calculi were reviewed.
