We assessed the efficacy of a fluoroscopically controlled cutting balloon catheter for the treatment of ureteropelvic junction and ureteral strictures.
A multicenter trial was performed that included 66 endopyelotomies and 49 endoureterotomies. To our knowledge this study represents the largest number of patients with ureteropelvic junction obstruction and ureteral strictures tested with this device to date.
With a mean followup of 7.8 months (range 1 to 17.9) the patency rate was 77% for endopyelotomy, with 72% of the primary and 100% of the secondary ureteropelvic junction obstructions remaining patent. The endoureterotomy patients were followed for an average of 8.7 months (range 1.2 to 17.0), with a patency rate of 55%.
A cutting balloon endoscopic incision is effective in the majority of cases, with patency rates for endopyelotomies and endoureterotomies that mirror current endourological reports using other, albeit more time intensive and more invasive, incisional techniques.
我们评估了在荧光透视控制下的切割球囊导管治疗肾盂输尿管连接处和输尿管狭窄的疗效。
进行了一项多中心试验，包括66例肾盂内切开术和49例输尿管内切开术。据我们所知，本研究是迄今为止使用该设备测试的患有肾盂输尿管连接处梗阻和输尿管狭窄患者数量最多的研究。
平均随访7.8个月（范围1至17.9个月），肾盂内切开术的通畅率为77%，原发性肾盂输尿管连接处梗阻的通畅率为72%，继发性梗阻的通畅率为100%。输尿管内切开术患者平均随访8.7个月（范围1.2至17.0个月），通畅率为55%。
切割球囊内镜切开术在大多数情况下是有效的，肾盂内切开术和输尿管内切开术的通畅率与目前使用其他切开技术（尽管耗时更长且侵入性更强）的腔内泌尿外科报告结果相当。
