Ureteropelvic junction obstruction (UPJO) is defined as an impairment of urine outflow from the pelvis to the ureter. Several treatment approaches are in use.
To present the different endo-urological approaches--retrograde and antegrade techniques --for UPJO using the holmium: YAG laser.
We followed 67 patients who underwent endopyelotomy between 1994 - 1997 and compared the different approaches for the treatment of UPJO.
A total of 67 patients were operated, 52 patients using retrograde approach and 15 using antegrade approach. In the retrograde approach success was achieved in 48 patients (93%) and in 14 patients (94%) in the antegrade approach. Complications rate was 10% and 40%, respectively. Hospital stay was 2.2 days in the retrograde approach and 4.6 in the antegrade approach.
The success rate in the different endourologic approaches was high and no difference between the two approaches was identified. From our experience, lower complication rate and shorter hospital stay make the retrograde approach more advantageous.
肾盂输尿管连接部梗阻（UPJO）被定义为尿液从肾盂流向输尿管的流出道受损。目前有几种治疗方法。
介绍使用钬激光治疗UPJO的不同腔内泌尿外科方法——逆行和顺行技术。
我们随访了1994年至1997年间接受肾盂内切开术的67例患者，并比较了治疗UPJO的不同方法。
总共67例患者接受了手术，52例采用逆行方法，15例采用顺行方法。逆行方法中48例（93%）成功，顺行方法中14例（94%）成功。并发症发生率分别为10%和40%。逆行方法的住院时间为2.2天，顺行方法为4.6天。
不同腔内泌尿外科方法的成功率较高，且两种方法之间未发现差异。根据我们的经验，较低的并发症发生率和较短的住院时间使逆行方法更具优势。
