目的探讨IVU/CT诊断小儿先天泌尿系畸形的意义。方法 35例疑诊肾积水,输尿管畸形,输尿管梗阻患儿输尿管畸形患儿,行IVU后,再行CT扫描,观察IVU和IVU/CT显示病变情况,并作对比分析。结果 (1)37侧例肾脏积水肾盂、肾盏及部分输尿管扩张;5侧例肾脏IVU不显影。(2)IVU/CT示UPJ 18侧例,UVJ7侧例,巨大输尿管6侧例,重复肾盂畸形5侧例,重复肾重复输尿管4侧例,先天性血管畸跨1侧例,盆腔移位肾1侧例,后尿道瓣膜1侧例。结论 IVU/CT可不依赖肾功能丧失程度显示泌尿系畸形;IVU/CT对小儿先天泌尿系畸形的诊断具有重要意义。
Objective To investigate the significance of IVU / CT in diagnosing congenital urinary malformation in children. Methods Thirty - five children with ureteral malformations diagnosed with hydronephrosis, ureter malformations and ureteral obstruction underwent IVU and then CT scan. IVU and IVU / CT were used to observe the pathological changes. Results (1) 37 cases of hydronephrosis renal pelvis, calyx and part of the ureter dilatation; 5 cases of renal IVU is not visualized. (2) IVU / CT showed UPJ 18 side cases, UVJ7 side cases, huge ureter 6 cases, repeated pyelonephrosis 5 cases, repeated renal ureteral 4 cases, congenital vascular malformations 1 case, pelvic transposition kidney 1 side case, 1 case of posterior urethral valve. Conclusion IVU / CT can show urinary malformations independent of the extent of renal dysfunction. IVU / CT is of great significance in the diagnosis of congenital urinary malformations in children.
