作者对113例病人非增强螺旋CT上确定的184个盆腔钙化进行了回顾性研究。其中36例伴有急性季肋部疼痛和血尿,确定38个输尿管远端结石。诊断结石的每例病人后来用对比剂强化研究(IVU、增强CT或逆行输尿管造影)证实或结石自然排出。其余77例无肾绞痛、血尿或输尿管结石病史,均经非增强螺旋CT估价各种非泌尿系情况而检出146个静脉石,这些静脉石沿着或接近盆腔输尿管行程的部位。CT从两肾顶部至膀胱底部扫描,
The authors performed a retrospective study of 184 pelvic calcifications identified on 113 patients with non-enhanced helical CT. Among them, 36 cases were accompanied with acute quarter rib pain and hematuria, 38 distal ureteral calculi were identified. Each patient diagnosed with stones was later confirmed by contrast-enhanced studies (IVU, enhanced CT or retrograde ureterography) or spontaneous discharge of stones. Of the remaining 77 patients with no history of renal colic, hematuria, or ureteral calculi, 146 non-urinary tract stones were detected by non-enhanced spiral CT. These vein stones were located along or near the pelvic ureter. CT scan from the top of both kidneys to the bottom of the bladder,
