Purpose. Relieving obstruction and protecting renal function are the main therapeutic purposes of obstructive uropathy which often involve surgical treatment, and the ureter catheter is one of the surgical instruments commonly used in surgery. We aimed to explore the innovative use of a ureter catheter in the surgery of obstructive uropathy. Methods. We used a ureteral catheter to innovate the surgical procedure of the most common causes of obstructive uropathy: ureteral calculi and stricture, establishing an internal circulation system (ICS), proposing a three-step dilatation method, and reviewing their effects on patients. Furthermore, we introduced a simple real-time intrapelvic pressure measurement device to monitor intrarenal pressure during operation. Results. Postoperative laboratory examination showed that blood CRP, leukocyte neutrophil level, changes in the hemoglobin, urine occult blood, and positive rate of urine culture in the ICS group are significantly lower than those in the control group, corresponding to a lower incidence of bleeding and infection-related complications clinically. A three-month follow-up revealed 1/3 rate of ureteral stricture in the ICS group comparing to the control. We applied the three-step dilatation in patients with severe stenosis in which the balloon could not pass; the overall effective rate was 90.9%. The pressure of the renal pelvis was displayed on the monitor in real time. The surgeon could estimate the degree of filling of the renal pelvis and adjust the intake volume through the data. Conclusion. The innovative application of ureteral catheters in the operation of obstructive uropathy can realize the real-time monitor of intraoperative renal pelvis pressure, reduce the incidence of lithotripsy postoperative complications, and expand the indications of balloon dilatation in ureteral stricture, which has certain clinical significance.

输尿管导管在尿路梗阻手术中的创新应用

目的。解除梗阻、保护肾功能是梗阻性尿路疾病的主要治疗目的，常涉及手术治疗，而输尿管导管是手术中常用的手术器械之一。我们旨在探索输尿管导管在梗阻性尿路病手术中的创新用途。方法。我们使用输尿管导管创新了梗阻性尿路疾病最常见原因的手术程序：输尿管结石和狭窄，建立了内循环系统（ICS），提出了三步扩张法，并回顾了它们对患者的影响。此外，我们介绍了一种简单的实时盆腔内压力测量装置，用于监测手术过程中的肾内压力。结果. 术后实验室检查显示ICS组血CRP、白细胞中性粒细胞水平、血红蛋白变化、尿潜血、尿培养阳性率明显低于对照组，对应出血和感染发生率较低-临床相关并发症。三个月的随访显示，与对照组相比，ICS 组的输尿管狭窄率为 1/3。我们对球囊无法通过的严重狭窄患者应用三步扩张术；总有效率90.9%。肾盂压力实时显示在监视器上。外科医生可以通过数据估计肾盂的充盈程度并调整摄入量。结论. 输尿管导管在梗阻性尿路病手术中的创新应用，可实现术中肾盂压力的实时监测，降低碎石术后并发症的发生率，扩大球囊扩张在输尿管狭窄处的适应证，具有一定的临床意义。
