Objective[WT5”BZ] To assess the value of magnetic resonance urography (MRU) for the noninvasive postoperative evaluation of renal transplants. [WT5”HZ]Methods[WT5”BZ] 28 cases of renal transplantation were examined with a modified,heavily T2 weighted fast apin echo pulse sequence and fat suppression pulse aid.Postprocedure processing was performed with a maxium projection(MIP) algorithm. [WT5”HZ]Results[WT5”BZ] 28 patients were studied. MRU revealed abnormal finding in 9 patients: mild dilatation of the renal pelvis without any urodynamic relevant obstruction (2), moderate dilatation of the renal pelvis(3),acute rejection(3), and ATN(1). Ureteral stenosis was diagnosed in 1 patients and treated surgically. [WT5”HZ]Conclusions[WT5”BZ] MRU is an alternative to conventional urinary tract images techniques. It requires no radiation or iodinated contrast material. It is reliable and noninvasive in depicting the urinary tract.MRU can be used as a noninvasive technique for assessment of renal transplantation in cases suspicious of complication in the excretory system.

目的 评价磁共振泌尿系造影技术对揭示肾移植术后尿路梗阻部位及原因的价值。 方法 用重T2加权快速自旋回波 (FSE)序列和脂肪抑制技术作MR泌尿系成像 2 8例。原发病均为慢性肾炎尿毒症 ,均为首次移植。临床诊断急性排斥 3例 ,移植肾肾功能延迟恢复 1例 ,B超显示移植肾轻度积水 2例 ,移植肾、输尿管中度积水 3例。所有图像均作最大信号强度投影 (MIP)处理。 结果  2 7例肾移植术后均清楚显示肾实质和泌尿系集合系统高质量的影像 ,除 1例移植肾肾衰患者外。 9例为阳性结果。阳性病种包括 :移植肾、输尿管中度积水 3例。 2例为移植肾轻度积水 ,未见输尿管膀胱吻合处狭窄 ,作临床随访。 3例为急性排斥反应 ,1例为移植肾肾衰。 结论 MR泌尿系成像是一种很可靠的、非侵袭性的检查方法 ,它不用造影剂 ,可避免碘副反应。在形态上 ,它能较好地显示泌尿系的解剖结构 ,是技术上的一大进步。对肾移植术后发生的输尿管外科并发症的诊断尤其有效及安全。

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.

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35%,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。

Objective To discuss the diagnostic value of spiral CT in ureteral diseases. Methods Spiral CT urography (SCTU) was performed in 27 cases with ureteral diseases, including 9 cases of ureteral calculus, 5 carcinomas, 9 stenosis, 1 malformation, 1 inflammation and 2 fistula. Of the 27 cases,15 also underwent non-enhanced spiral CT scan and 10 received intravenous urography(IVU). Results (1) Eight cases of radiolucent ureteral calculus were clearly showed by nonenhanced spiral CT. (2) On SCTU, the location and diameter of 9 ureteral calculus(8 radiolucent, 1 radiopaque) and enlargement of renal pelvis and ureter were displayed. Irregular ureteral wall, local rarefication or obstruction of contrast medium in ureter were detected in 5 case of tumor.Ureteral lumen was narrowed gradually in 7 cases of simple ureteral stenosis without thickening of the wall. Two cases with ectopic vessel compression were clarified at the boundary of ureter and pelvis. 1 malformation with double renal pelvis and ureter was demonstrated. The location and direction of ureteral fistula were notified. Conclusion SCTU is superior to IVU and conventional CT in improving diagnostic accuracy of ureteral disease.

目的 探讨螺旋CT及其泌尿系成像 (spiralCTurography ,SCTU)技术对输尿管病变的诊断价值。方法  2 7例输尿管病变患者中 ,结石 9例、肿瘤 5例、狭窄 9例、畸形 1例、炎症 1例及输尿管瘘 2例。均行螺旋CT泌尿系检查。注射对比剂后 10~ 15min行螺旋CT容积扫描 ,在工作站利用软件进行图像后处理 ,获得泌尿系立体图像。其中 15例同时行螺旋CT平扫 ,10例行静脉泌尿系造影。结果  (1)螺旋CT平扫 8例阴性结石清晰可见。 (2 )SCTU图像上 ,8例阴性和 1例阳性结石可见其位置、形态、大小及扩张的肾盂和输尿管 ;5例输尿管肿瘤可见局部管腔内对比剂柱变细或突然中断 ,管壁不光整 ;7例单纯狭窄可见狭窄部位管腔逐渐变细 ,管壁无明显增厚。 2例迷走血管压迫致狭窄者均位于肾盂输尿管交界处 ;1例重复肾并输尿管畸形者显示双肾盂、双输尿管 ;输尿管瘘者显示瘘口位置、走行。结论 与普通CT及静脉泌尿系造影 (IVU)相比 ,螺旋CT及其SCTU技术有明显优越性 ,可使输尿管病变诊断准确率明显提高
