加注0.9%氯化钠溶液在MSCTU中显示输尿管的应用价值

目的探讨MSCT在泌尿系统造影中输尿管全程显示的技术与效果。方法选择无严重肾功能不全、无双侧尿路梗阻的泌尿系统螺旋CT扫描的病例60例,其中30例注射对比剂90~100m l,30例另外加注60m l 0.9%氯化钠溶液,进行CT三维重建,对输尿管全程显示进行对比。结果一组30例单纯注射对比剂,肾盂、输尿管全段及膀胱15m in全尿路显示8例（8/30）,占26.6%;22例未能显示输尿管下段（22/30）,占73.3%。二组30例注射对比剂后加注60m l 0.9%氯化钠溶液,肾盂、输尿管全段及膀胱15m in全尿路显示25例（25/30）,占83.3%,其中12例单侧输尿管梗阻未充盈,健侧肾盂输尿管全段及膀胱充盈;5例未能显示输尿管下段（5/30）,占16.6%。结论注射对比剂后加注0.9%氯化钠溶液,有助于提高泌尿系统全程显示率,并缩短全尿路充盈时间。
