目的:探讨经输尿管镜直视下气囊扩张术治疗输尿管狭窄的疗效。方法:经输尿管镜直视下气囊扩张术治疗50例输尿管狭窄患者,通过尿路排泄造影,肾脏逆行造影,CT,超声等检查观察手术的总有效率、不良反应及并发症。结果:总有效率为96%(48/50)。术后患者除出现轻度肉眼血尿及尿频、尿急、尿痛外,无腹膜后囊肿或脓肿形成等并发症。结论:经输尿管镜直视下气囊扩张术治疗输尿管狭窄,可使狭窄段或疤痕均匀裂开,具有扩张成功率高、疗效好、不良反应轻及并发症少的优点,是治疗输尿管狭窄的好选择。
Objective: To investigate the curative effect of ureteroscopic balloon dilatation for ureteral stricture under ureteroscopy. Methods: 50 cases of ureteral stricture underwent direct ureteroscopy under ureteroscopy. The total operative efficiency, adverse reactions and complications were observed by urography, renal retrograde angiography, CT and ultrasonography. Results: The total effective rate was 96% (48/50). In addition to mild postoperative patients with gross hematuria and urinary frequency, urgency, dysuria, no retroperitoneal cyst or abscess and other complications. Conclusions: Ureteroscopic balloon dilatation under ureteroscopy for the treatment of ureteral stricture, the stenosis or scar can be split evenly, with the advantages of high success rate, good curative effect, less adverse reactions and fewer complications, is the treatment of ureteral stricture select.
