摘　　要：目的探讨经皮肾穿刺经尿道建立导丝轨道置入双J管治疗输尿管狭窄和梗阻的方法并评价其疗效。方法 75例输尿管狭窄或梗阻患者(其中良性狭窄60例,恶性狭窄15例)在膀胱镜插管失败情况下,均采用经皮肾穿刺经尿道建立导丝轨道,沿导丝轨道经尿道置入球囊导管扩张狭窄段并置入双J管。随访3个月至5年。结果手术成功率98.7%(74/75),良性狭窄患者中1例失败。治愈率70.7%(53/75),好转率26.7%(20/75),无效1例(1.35%),总有效率97.3%(73/75)。结论经皮肾穿刺经尿道建立导丝轨道置入双J管治疗输尿管狭窄和梗阻是一种安全有效的方法。Objective To explore the technique of implantation of double-J stent via the guide-wire track, which was established through percutaneous renal puncturing, for the treatment of ureteral stricture and obstruction, and to evaluate its therapeutic effect. Methods A total of 75 patients with ureteral stricture or obstruction, who failed to respond to cystoscopic catheterization, were enrolled in this study. The lesions included benign stricture （n = 60） and malignant stricture （n = 15）. Ureteral guide-wire track was established through percutaneous renal puncturing, which was followed by the dilatation of the stricture with balloon catheter and subsequent implantation of double-J stent via the guide-wire track. After the double-J stent was removed, the patients were followed up for 3 months to five years. Results The success rate of the procedure was 98.7%（74/75）. Technical failure occurred in one patient with benign ureteral stricture. The cure rate was 70.7%（53/75）, the improvement rate was 26.7% （20/75）, and no improvement was seen in one ease （1.35%）. The total effective rate was 97.3% （73/75）. Conclusion For the treatment of ureteral stricture and obstruction, the implantation of double-J stent via the guide-wire track, which is established throughpercutaneous renal puncturing, is a safe and effective method. （J Intervent Radiol, 2014, 23： 445-448 ）
