梗阻性肾积水的影像学诊断（附96例报告）

为评价各种影像学检查方法对梗阻性肾积水的诊断价值，对96例梗阻性肾积水病人资料进行分析，结果表明所有病人均行超声及静脉肾盂造影检查，35例做逆行肾盂造影检查，20例行腹部CT检查，40例做过膀胱镜检查。其中，输尿管结石58例，占60％，输尿管狭窄15例，占16％，输尿管肿瘤7例，占7．3％，输尿管囊肿13例，占13．5％，先天性巨输尿管症3例，占3．1％。静脉肾盂造影阳性率为36％，超声检查81％，逆行肾盂造影100％，CT检查75％，膀胱镜检查50％。因此认为多种病因引起的梗阻性肾积水有其特征性的影像学表现，准确合理的选择影像学检查方法对确定梗阻部位及病因，具有重要的临床价值。

The imaging diagnosis of obstructive hydronephrosis (A Report of 96 Cases)

To study the imaging diagnosis of obstructive hydronephrosis and appreciate the value of various imaging examination methods including intravenous pyelography and B-Ultrasonography respectively, retrogradepyelography. CT examination, cystocopy. 96 cases were analyged retrospectively, It is showed the causes of 96 cases obstructive hydronephrosis were ureterolithes 58 cases (60%). ureteral stenosis 15 crises (16%), ureteral carcinoma 7 cases(7. 3%),ureteral cyst 13 cases (13.5%), nervous bladder 3 cases (3.1%). The sensitivity of intravenous pyelogrnp-hy was 81%, B-ultrasonograply 36%. retrograde-pyelography 100%, Ct examination 75%, and cystocopy 50%, respverively. It suggested obstructive by-dronephrosis that various origin of diseases cause have the characteristie imaging findings. In order to decide the position and causes of ureteric obstruction, choosing correct and reasonable imaging methods have impor-tent clinical value.
