Aanalysis of digital tomosynthesis system with no oppression intravenous urography in the diagnosis of urinary stones
Objective To explore the clinical application value of the digital tomosynthesis system with no oppression intravenous urography in diagnosis of urinary stones. Methods 2009-2012 227 clinical suspicion of urinary calculi patients, including 25 cases of patients should not undergo conventional intravenous pyelography, undergo digital tomosynthesis system with no oppression intravenous pyelography, other patients were randomized to undergo the conventional intravenous pyelography inspection or digital tomosynthesis system with no oppression intravenous pyelography, recording two methods of diagnosis of urinary calculi, CT examination or clinical follow-up results were compared. Results In 227 patients, urinary calculi were found in 33 cases. digital tomosynthesis system with no oppression intravenous pyelography group: 126 patients, the diagnosis of kidney stones in 14 cases, 2 cases of ureteral stones, smallest stone diameter 0.3cm, confirmed by CT or clinical, one cases were found missed. The traditional intravenous urography group: 101 patients, 13 cases of diagnosis of kidney stones, ureteral stones two cases, the minimum diameter of the stones was 0.5cm, CT or clinically proven, one case were missed. DTS with no oppression urography group, sensitivity 94.12%, specificity 99.08% of the diagnosis of urinary stones. Conventional intravenous pyelography group: the diagnosis of urinary stones sensitivity 87.5%, specificity of 97.65%. Conclusion Compared with conventional intravenous urography in the diagnosis of urinary calculi, digital tomosynthesis system with no oppression intravenous pyelography can find more, smaller stones, patients better tolerated.
