OBJECTIVE: To investigate the value of X-ray digital tomosynthesis (DTS) in the diagnosis of urinary stones compared with kidney ureter bladder radiography.
METHODS: Between February 2011 and February 2012, 80 consecutively enrolled patients with urinary stones proved by UMDCT, the total number of which was 138, underwent additional DTS and KUB (kidney, ureter and bladder) then the number of stones and the proportions (the sensitivity of detecting stones) were recorded under all kinds of circumstances. Any two cases were selected in comparison with each other among the following four cases (DTS and KUB before and after bowel preparation).The data from all cases were statistically processed by chi-square test of four-fold table.
RESULTS: The diagnostic sensitivity of DTS before and after bowel preparation, KUB before and after preparation were 94.2%, 96.4%, 47.8% and 66.7%, respectively. No significant differences between DTS before bowel preparation and DTS after bowel preparation were found. Significant differences were observed in other five ways.
CONCLUSION: DTS is hardly affected by intestinal gas, feces and bones compared with KUB. Use of DTS results in improved detection rate and definition of stones with the same positioning function as KUB.
