Advances in endosurgical technology have provided the urological surgeon with an alternative to open surgery for the treatment of ureteral strictures. We report the use of an endoscopic intraureteral incision (endoureterotomy) followed by balloon calibration to treat benign ureteral strictures in 13 patients. With an average subjective and objective followup among successful endoureterotomies of 20 months (all cases 12 months or greater), the overall success rate for this procedure is 62%. Of these patients 5 also received triamcinolone injections into the stricture bed following incision and dilation. This method appeared to influence favorably subsequent ureteral patency. The only operative complication was a urinoma, which resolved without intervention. Endoureterotomy appears to be a safe and reasonably effective modality for the treatment of ureteral stricture disease.
腔内手术技术的进步为泌尿外科医生提供了一种替代开放手术治疗输尿管狭窄的方法。我们报告了13例采用内镜下输尿管内切开术（输尿管内切开术）并随后进行球囊扩张术治疗良性输尿管狭窄的病例。成功进行输尿管内切开术的患者平均主观和客观随访时间为20个月（所有病例均为12个月或更长时间），该手术的总体成功率为62%。在这些患者中，有5例在切开和扩张后还接受了曲安奈德注射到狭窄部位。这种方法似乎对随后的输尿管通畅有积极影响。唯一的手术并发症是尿外渗，未经干预即自行消退。输尿管内切开术似乎是治疗输尿管狭窄疾病的一种安全且相当有效的方式。
