Abstract: Purpose:To study the diagnostic value of using ultrasonography(US)、plain film of the abdomen(KUB)、 intravenous urography (IVU) in acute ureteral calculous obstruction. Methods: The routine B-US、diuretic US、 KUB、 IVU were retrospectively analyzed in 352 cases of acute ureteral calculous obstruction.Results: Of all the patients, 83.2 % (293/352) 、 96.6 % (340/352)were diagnosed as hydronephrosis by routine B-US、 routine B-US plus diuretic US, respectively. The hydronephrotic diagnosis of 59 suspected patients were79.7% (47/59)using diuretic US. The ureteral calculous dignosis of US、KUB、US plus KUB were 76. 1 % (268/352 )、81.6(284/348)and 91.8(323/352),respectively. Conclusion:The routine B-US is an effective method todiagnose acute upper urinary tract obstruction,and routine B-US plus diuretic US is more valuable. B-US plusKUB is the first approach to diagnose ureteral calculi.
