逆行气囊扩张及内切开术治疗泌尿系梗阻性疾病

Cutting balloon catheter device for treatment of ureteropelvic junction obstruction and posterior urethral stricture

目的 :探讨带电切导丝的气囊扩张导管在泌尿系梗阻性疾病治疗中的价值。方法 :采用带电切导丝的气囊扩张导管对泌尿系梗阻患者 7例 (包括肾盂输尿管连接部狭窄 5例 ,小儿陈旧性后尿道狭窄 2例 )同时进行狭窄部位扩张及内切开术 ,术毕置入双 J管及气囊导尿管 8～ 12周。结果 :所有患者治疗经过顺利 ,术后恢复快 ,住院时间短 ,效果满意。结论 :带电切导丝的气囊扩张导管是治疗泌尿系梗阻性疾病的有效方法 。

Purpose:To evaluate the role of retrograde dilatation and endopyelotomy and internal urethrotomy with the cutting balloon catheter device for treatment of ureteropelvic junction (UPJ) obstruction and posterior urethral stricture.Methods:Five patients (primary:1,secondary:4,male:2,female:3,)with UPJ obstruction and two patients with posterior urethral stricture were treated by the cutting balloon catheter device. After dilatation by the balloon and cutting the stenotic area electrically using cutting wire, double J stent(7 Fr) or Foley catheter was inserted and kept in position for 8～12 weeks.Results:All patients have been well and without recurrence on following up for 1 year.Conclusions:UPJ obstruction and posterior urethral stricture may be easily and safely treated by retrograde endopyelotomy and internal urethrotomy with the cutting balloon catheter device.
