To evaluate spiral CT urography (SCTU) and CT virtual endoscopy (CTVE) in detecting urologic diseases.
SCTU was performed in 46 patients with urological diseases including renal neoplasms (2), paropelvic cysts (2), ureteral calculi (6), ureteral stenosis (4), ureteral neoplasms (2), double kidneys and ureter malformation (1), bladder neoplasms (28) and bladder endometreosis (1). The 6 patients with ureteral diseases and 29 patients with bladder diseases underwent CTVE based on spiral CT scan. All CTVE findings were compared with those of B-mode ultrosonography, intravenous urography (IVU), retrograde pyelography (RGP), conventional CT or cystoscopy.
All upper urinary tract diseases and bladder diseases (28 cases) were detected by SCTU and CTVE scans and they were confirmed operatively or pathologically except one case of bladder neoplasm (diameter less than 5 mm) was missed.
SCTU and CTVE have proved to be non-invasive and reliable in the diagnosis of urological diseases and are superior to IVU or conventional CT. CTVE can serve as a supplementary method to fiberoptic cystoscopy or ureteroscopy.
评估螺旋CT尿路造影（SCTU）和CT虚拟内镜（CTVE）在检测泌尿系统疾病中的作用。
对46例泌尿系统疾病患者进行SCTU检查，这些疾病包括肾肿瘤（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）、重复肾及输尿管畸形（1例）、膀胱肿瘤（28例）和膀胱子宫内膜异位症（1例）。对6例输尿管疾病患者和29例膀胱疾病患者在螺旋CT扫描基础上进行CTVE检查。将所有CTVE检查结果与B超、静脉尿路造影（IVU）、逆行肾盂造影（RGP）、传统CT或膀胱镜检查结果进行比较。
所有上尿路疾病和膀胱疾病（28例）均通过SCTU和CTVE扫描检测到，除1例直径小于5mm的膀胱肿瘤漏诊外，其余均经手术或病理证实。
SCTU和CTVE已被证明在泌尿系统疾病诊断中具有无创性和可靠性，且优于IVU或传统CT。CTVE可作为纤维膀胱镜或输尿管镜检查的补充方法。
