【摘要】目前在國外CT尿路造影（CT urography，CTU）已得到廣泛應(yīng)用，特別是對無痛性血尿患者的病因探查，以及對尿路上皮腫瘤的診斷具有重要價(jià)值。輻射劑量過大是限制CTU應(yīng)用的主要矛盾，提高成像質(zhì)量及減少輻射劑量的技術(shù)種類繁多，效果不一致，尚缺乏統(tǒng)一標(biāo)準(zhǔn)，有待進(jìn)一步研究。

Methods We collected the clinical data of 132 patients who were diagnosed with upper urinary tract obstruction by 64-slice spiral CT urography between December 2009 and January 2011. We analyzed the imaging features and compared them with surgical and pathological results. Results Confirmed by surgical and pathological results, 132 patients included 31 cases of urethral stone, 51 cases of congenital variant and malformation, 16 cases of ureteral infection, 29 cases of tumors in urinary tract, 3 cases of extraneous compression, and 2 cases of cysts next to the renal pelvis. CT diagnosis for all cases were basically in line with clinical and pathological results. Conclusion CT urography is an extremely valuable imaging method to diagnose the diseases of urinary system. It can display lesions broadly and reveal their inner and peripheral circumstances clearly, thus can help us determine the reasons and natures of the lesions precisely.
