Sixteen cases of pyeloureteral obstruction treated in the period of 24 months are reported. The differential diagnosis, specially with Wilms' tumor must be considered. The low frequency of obstruction secondary to aberrant vessels is also important as etiological cause of pyeloureteral obstruction. This situation contributes to obstruction, but is not the main cause; the same is true with the anomalous implantation of the ureter in the renal pelvis. Within the possible etiological causes, the impairment of function of the pyeloureteral junction must be mentioned as responsible of the dilatation of the renal pelvis. Quite possibly such dysfunction is secondary to an abnormal disposition of the muscle fibers, the same as to the presence of fibrous tissue at the level of said junction. The dynamic evaluation of the ureteropyelic junction was used in two ways, systemic and local, to decide the surgical intervention. The functional evaluations is quite important to avoid unnecessary surgery. Anderson-Hynnes' technique was used to avoid frequent relapses observed when etiological treatment is not done. The correct application of the technique is important to obtain good results.
报告了24个月内治疗的16例肾盂输尿管梗阻病例。必须考虑鉴别诊断，特别是与肾母细胞瘤的鉴别。异常血管继发梗阻的低发生率作为肾盂输尿管梗阻的病因也很重要。这种情况会导致梗阻，但不是主要原因；输尿管在肾盂中的异常植入也是如此。在可能的病因中，肾盂输尿管连接部功能受损必须被提及，它是肾盂扩张的原因。很可能这种功能障碍继发于肌肉纤维的异常排列，就像在该连接部存在纤维组织一样。输尿管肾盂连接部的动态评估通过全身和局部两种方式用于决定手术干预。功能评估对于避免不必要的手术非常重要。采用安德森-海恩斯技术以避免在未进行病因治疗时经常出现的复发。正确应用该技术对于获得良好效果很重要。
