由于近年来经皮肾内手术的开展,对先天性肾盂输尿管连接部梗阻的病例经皮行肾盂内切开手术已有成功的报导.后者报告了12例病人,10例经皮肾盂内切开技术获得成功,另2例因有异常肾下极动脉经腰切口施行了肾盂成形术.手术方法是将肾盂镜经皮放入肾盂(肾中盏处)内,送一导丝进入输尿管内,在内窥镜窥视下用冷叶刀作肾盂输尿管(狭窄处)切开,在后侧部切开,将该处全层切开可见到黄色脂肪,切口长达1.5～2.0cm,约有1cm超过狭窄处到正常的上段输尿管.切开后可沿导丝放入一带囊导管,在透视下观察注入造影剂,
Due to recent advances in percutaneous nephrostomy, there have been successful reports of percutaneous endoscopic pyeloplasty in patients with congenital ureteropelvic junction obstruction, the latter of which reported 12 patients and 10 percutaneous renal pelvis incisions Open technique was successful, and the other 2 cases of renal pelvis angioplasty due to abnormal renal artery aneurysm incision.Purification is to put the renal pelvis into the renal pelvis (renal calculus), send a guide wire into the ureter , In the endoscopic peep with a cold blade for ureteropelvic (stenosis) incision, incision in the posterior part of the full-thickness incision can be seen yellow fat, incision up to 1.5 ~ 2.0cm, about 1cm beyond the stenosis to the normal upper ureter.After incision can be placed along the guide wire catheter ducts, under the perspective of observation into the injection of contrast agent,
