目的 探讨螺旋CT尿路成像 (SCTU)与CT仿真内窥镜 (CTVE)的检查方法、成像技术以及在泌尿外科疾病中的应用价值 ,提高诊断水平。 方法 应用螺旋CT对 4 6例泌尿系疾病患者 (包括肾肿瘤 2例 ,肾盂旁囊肿 2例 ,输尿管结石 6例 ,输尿管狭窄 4例 ,输尿管肿瘤 2例 ,重复肾重复输尿管畸形 1例 ,膀胱肿瘤 2 8例 ,膀胱子宫内膜异位症 1例 )行容积扫描 ,所得数据在工作站利用软件进行后处理 ,获得泌尿系立体图像 ;并对 6例输尿管疾病、2 9例膀胱疾病患者进行了CT仿真内窥镜(CTVE)成像。所有图像均与B超、静脉尿路造影、逆行肾盂造影、常规CT扫描、膀胱镜检查等比较 ,并将术中所见或病理结果作为诊断的金标准。 结果 所有患者均取得了高质量的泌尿系图像 ,除1例膀胱肿瘤 (肿瘤直径为 4mm)漏诊外 ,其余患者均得到了明确诊断 ,并与手术或病理结果相符合。结论 SCTU与CTVE是较可靠的非侵入性检查手段 ,具有一定的优越性 ,可作为泌尿系常规检查方法的有益补充
Objective To investigate the diagnostic methods of spiral CT urography (CTTU) and CT virtual endoscopy (CTVE), imaging techniques and their value in urological diseases and to improve their diagnostic value. Methods Spiral CT was performed on 46 patients with urinary diseases (including 2 renal tumors, 2 renal pelvis cysts, 6 ureteral calculi, 4 ureteral stenoses, 2 ureteral tumors, 1 repeat renal duplication ureter, 1 bladder cancer 28 cases, 1 case of bladder endometriosis) volume scanning, the data obtained at the workstation using software for post-processing, to obtain three-dimensional images of the urinary tract; and 6 cases of ureteral disease, 29 cases of bladder disease patients CT Virtual endoscopy (CTVE) imaging. All images were compared with B ultrasound, intravenous urography, retrograde pyelography, conventional CT scan, cystoscopy, etc., and the intraoperative findings or pathological findings as the gold standard for diagnosis. Results All the patients had high quality urological images. Except for the missed diagnosis of one case of bladder tumor (tumor diameter 4mm), all the other patients had a clear diagnosis and were consistent with the surgical or pathological findings. Conclusion SCTU and CTVE are more reliable and noninvasive means of examination. They have some advantages and can be used as a useful supplement to routine urological examination
