Although the true incidence of ureteropelvic junction (UPJ) obstruction in the lower-pole moiety of an incompletely duplicated renal collecting system remains elusive, the description of this entity in the published literature is exceedingly rare. To our knowledge, we report the first case of this entity managed successfully by ureteroscopic holmium laser incision of the stenotic UPJ segment. This case underscores the utility of minimally invasive techniques in the management of selected cases of UPJ obstruction associated with a partially duplicated collecting system.
虽然在不完全重复肾集合系统的下极部分中输尿管肾盂连接部（UPJ）梗阻的真实发病率仍不清楚，但已发表文献中对该实体的描述极为罕见。据我们所知，我们报告了首例通过输尿管镜钬激光切开狭窄的UPJ节段成功治疗该实体的病例。该病例强调了微创技术在处理与部分重复集合系统相关的特定UPJ梗阻病例中的实用性。
