The utility model discloses a ureteral catheter with a balloon. The ureteral catheter has an insertion end and an external end. There are three independent channels in the ureteral catheter, namely, a water injection channel, a balloon channel and a wire guide channel. The balloon channel is connected with a balloon located in the catheter body, and the balloon channel is initially located in the ureteral catheter. The external end of the ureter terminates in the balloon; the outlet of the water injection channel is located at the insertion end of the ureteral catheter, the water injection port is located at the external end of the ureteral catheter, and the water injection channel runs through the entire ureteral catheter; the wire guide channel runs through the entire ureter catheter from the insertion end of the ureteral catheter to the external end of the ureteral catheter. The catheter. The utility model has the advantages of simple structure and low cost, and can effectively improve the success rate of indwelling ureteral stent for patients with acute obstruction of ureteral calculi, realize the drainage of the affected side of ureter and kidney, alleviate or eliminate the pain caused by obstruction of ureteral calculi, and reduce the complications caused by obstruction of ureteral calculi.

技术介绍
输尿管结石合并顽固性肾绞痛临床上极为常见。部分输尿管结石并肾绞痛病人由于常规处理疗效不确切,时而引起患者和家属对医院和医护的不满,由此导致的医患冲突不为少见。肾绞痛时患侧肾恢复引流不及时可导致肾功能损害、尿源性脓毒血症,双侧输尿管结石和孤立肾肾绞痛可致肾衰,孕妇的肾绞痛可导致流产和早产,肾绞痛合并糖尿病、慢性心肺疾病等基础疾病的患者可发生尿源性休克和死亡。除了对症治疗和药物排石、输尿管镜碎石、肾穿刺造瘘引流,膀胱镜下输尿管逆行插管引流和留置输尿管内支架也是输尿管结石急性梗阻病人治疗中常见的操作。常规的膀胱镜下输尿管逆行插管和留置内支架,可以实现部分患者的肾和输尿管引流。相对常规输尿管逆行插管,本申请人的“带球囊的输尿管逆行治疗管道套件”(申请号或专利号:201621306085.7)可以增加输尿管逆行插管的成功率。1、结石梗阻后,膀胱镜下输尿管逆行插管,或者膀胱镜留置导丝后顺导丝留置内支架的操作中,常常遇到结石梗阻后、结石周围的输尿管腔隙不足以让输尿管导管或者导丝越过,导致逆行插管和留置输尿管内支架成功率不高,救治效果明显下降。2、本申请人已经申请了“带球囊的输尿管逆行治疗管道套件”(申请号或专利号:201621306085.7),该专利可实现结石所在段输尿管扩张,以及在输尿管被动扩张的条件下的引流管置入,但它有三个不足:1)导管A和导管B(以及导管C和导管D)实现二者间无间隙接触、且两管又能基本无摩擦滑动较困难,可能导致产品成本高;如果两者之间间隙难以控制 ...
【技术保护点】
1.一种带球囊的输尿管导管,所述输尿管导管设有插入端与体外端,其特征在于:所述输尿管导管内设有三个独立的通道,即注水通道、球囊通道与导丝通道,所述球囊通道和球囊相连通,球囊通道起始部位于输尿管导管的体外端,终止于球囊;所述注水通道的出水口位于输尿管导管的插入端,注水口位置位于输尿管导管的体外端,注水通道贯穿整条输尿管导管;所述导丝通道从输尿管导管的插入端到输尿管导管的体外端,贯穿整条输尿管导管。
