To compare the accuracy of unenhanced, helical CT with sonography for the detection of complications of urinary tract reconstruction.
Forty-six kidneys in 24 patients were examined with CT and sonography. All scans were assessed for ease of renal visualization, presence of renal, ureteral, and bladder calculi, renal scars, hydronephrosis, and abdominal wall hernia. The results of both imaging modalities were independently reported.
CT provided excellent visualization of all 46 kidneys, while sonography provided poor visualization of 8 kidneys (17%) (P < 0.001). CT detected calculi in 10 kidneys, 1 ureter, and 7 bladders. Sonography detected calculi in only 2 kidneys, and 2 bladders. Overall, CT detected significantly more calculi than US (18 vs 4, P = 0.01). CT detected scarring in 15 kidneys, while sonography detected scarring in 10. Hydronephrosis was detected in 6 kidneys by CT and in 8 kidneys by sonography. Three abdominal wall hernias were seen at CT that were not seen at sonography.
CT is superior to sonography for the detection of urinary tract calculi and renal scarring. CT will demonstrate abdominal wall hernias that are unsuspected.
比较非增强螺旋CT与超声检查在检测尿路重建并发症方面的准确性。
对24例患者的46个肾脏进行了CT和超声检查。评估所有扫描图像的肾脏显影清晰度、肾、输尿管和膀胱结石的存在情况、肾瘢痕、肾积水及腹壁疝。两种成像方式的结果分别独立报告。
CT能清晰显示所有46个肾脏，而超声对8个肾脏（17%）显影不佳（P < 0.001）。CT检测到10个肾脏、1条输尿管和7个膀胱中有结石。超声仅检测到2个肾脏和2个膀胱中有结石。总体而言，CT检测到的结石明显多于超声（18个对4个，P = 0.01）。CT检测到15个肾脏有瘢痕，超声检测到10个。CT检测到6个肾脏有肾积水，超声检测到8个。CT发现3例腹壁疝，超声未发现。
在检测尿路结石和肾瘢痕方面，CT优于超声。CT能显示未被怀疑的腹壁疝。
