Ureterectasia can be congenital (mega-ureter) or acquired (hydro-ureter). Mega-ureters can be of reflux and non-reflux (obstructive) type. The essence of primary non-reflux mega-ureters is the presence of a prevesical adynamic segment which causes functional obstruction. The musculature of this segment is abnormal in both function and structure. A surgical solution of the malformation is recommended mainly in children and young adults. In 10 years, 17 patients were subjected to 22 operations. After removal of the obstructive segment and straightening of the ureter, it was implanted into the vesicle through an intravesical tunnel. With the exception of two cases where nephrectomy had to be done and a case with persisting reflux, the other operations were successful. Narrowing of the ureter was not done. Ureteral neo-implantation is preferred to Boari's operation. Isolated pelvis ureters are operated only in the case of complications.
输尿管扩张可分为先天性（巨输尿管）或后天性（输尿管积水）。巨输尿管可分为反流型和非反流型（梗阻型）。原发性非反流性巨输尿管的本质是膀胱前动力缺失段的存在，该段会导致功能性梗阻。该段肌肉组织在功能和结构上均异常。主要建议对儿童和年轻成年人进行该畸形的手术治疗。10年间，17例患者接受了22次手术。切除梗阻段并使输尿管变直后，通过膀胱内隧道将其植入膀胱。除了两例必须进行肾切除术的病例和一例持续存在反流的病例外，其他手术均成功。未进行输尿管狭窄手术。输尿管新植入术优于鲍里手术。孤立性盆腔输尿管仅在出现并发症时才进行手术。
