目的 分析输尿管非结石梗阻性肾积水的影像特征 ,提高对其的识别能力。方法 根据静脉肾盂造影、逆行尿路造影结果 ,对自 1997-0 1～ 2 0 0 4-0 2经手术和病理证实的输尿管非结石性梗阻肾积水 5 7例的影像及病理资料进行对照分析。结果 中、重度肾积水 47例 ,占 82 .5 % ,其中重度肾积水 2 3例中 ,输尿管肾盂高位连接 12例 ,低位连接 8例 ,输尿管局限狭窄的发病率为85 .1% ,其中输尿管多发和 /或双侧输尿管狭窄的发病率为 2 2 .0 % ,其它原因所致输尿管狭窄的发生率为 14 .9%。结论 输尿管非结石性梗阻的病因具有多样性 ,肾积水的不同影像改变与输尿管病变位置不同密切相关。当一侧肾为重度积水 ,另一侧肾盂表现为“壶腹”型肾盂时应注意排除双侧输尿管存在病变的可能性
Objective To analyze the imaging features of ureteral obstruction hydronephrosis and improve its ability of recognition. Methods According to the results of intravenous pyelography and retrograde urography, the imaging and pathological data of 57 cases of ureteral calculi with hydronephrosis confirmed by operation and pathology from 1997 to 2004 were compared analysis. Results, 47 cases of severe hydronephrosis, accounting for 82.5%, of which 23 cases of severe hydronephrosis, ureter high renal pelvis connection in 12 cases, low connection in 8 cases, the incidence of ureteral stricture was 85.1% The incidence of multiple ureteral obstruction and / or bilateral ureteral stricture was 22.0%. The incidence of other ureteral strictures was 14.9%. Conclusion The causes of ureteral obstruction are diverse. The different images of hydronephrosis are closely related to the location of ureteral lesions. When the side of the kidney as severe hydronephrosis, the other side of the renal pelvis showed “ampulla” type renal pelvis should be precluded the possibility of precluding bilateral ureteral lesions
