Congenital midureteral stricture is an uncommon cause of prenatal hydronephrosis, and it is generally associated with proximal hydroureteronephrosis . We report a unique case of a congenital severe midureteral dilatation associated with mild proximal ureteral dilatation and normal distal ureteral diameter. The dilated midureter was excised, and an open end-to-end ureteroureterostomy was performed. Follow-up 6 months after surgical correction revealed marked improvement in the left-sided hydronephrosis and complete resolution of the hydroureter.
先天性中段输尿管狭窄是产前肾积水的罕见原因，通常与近端输尿管肾盂积水有关。我们报告了一例独特的病例，该病例为先天性严重中段输尿管扩张，伴有轻度近端输尿管扩张且远端输尿管直径正常。切除扩张的中段输尿管，并进行了开放式端端输尿管输尿管吻合术。手术矫正6个月后的随访显示，左侧肾积水有明显改善，输尿管积水完全消退。
