目的探讨CT尿路成像(CTU)结合输尿管镜在肾盂输尿管梗阻性病变中的诊断价值。方法选取我院图像存储与传输系统内超声检查病因不明的肾盂输尿管梗阻患者45例,行CTU及输尿管镜检查,分析CTU图像,结合内窥镜下治疗及病理检查,确定梗阻原因及部位。结果45例中,梗阻结石18例,肿瘤9例,肾盂输尿管交界狭窄5例,炎性狭窄5例,结核3例,肾盂旁囊肿2例,输尿管囊肿1例,输尿管息肉1例,医源性狭窄1例。结论 CTU结合输尿管镜对于肾盂输尿管梗阻性病变有很好的诊断价值。结合内窥镜下治疗及取得病变的病理,可为临床诊断及治疗方案的确定提供可靠依据。
Objective To investigate the value of CT urography combined with ureteroscopy in the diagnosis of ureteropelvic obstructive lesions. Methods Forty-five patients with ureteropelvic obstruction diagnosed by echocardiography in our hospital image storage and transmission system were selected. CTU and ureteroscopy were performed. CTU images were analyzed. Combined with endoscopic treatment and pathological examination, the cause and location of obstruction were determined. Results Among the 45 cases, 18 were obstructive stones, 9 were tumors, 5 were ureteropelvic junction strictures, 5 were inflammatory stenoses, 3 were tuberculosis, 2 were renal plexus cysts, 1 was ureteral cyst, 1 was ureteral polyps, and iatrogenic 1 case of stenosis. Conclusion CTU combined with ureteroscopy for ureteropelvic obstructive lesions have a good diagnostic value. Combined with endoscopic treatment and pathological lesions can provide a reliable basis for clinical diagnosis and treatment programs.
