Purpose: To explore the value of diagnosis on urine flow related diseases by applying of 640-slice MDCT four-dimension dynamic imaging.
Methods and materials: Sixteen patients were clinically diagnosed with urine flow related diseases, and detail diagnostic information could not be provided by other routine imaging exam. Four-dimension dynamic CT imaging was performed for diagnosis by the 640-slice MDCT with a 160-mm detector, which was approved by the ho[...]
Results: Four cases of slight urine reflux were confirmed. Four cases of stenosis of lower ureter were found (2 of moderate stenosis, and 2 of severe stenosis). The locations of ectopic ureter were accurately defined in five cases. The precise locations and sizes of fistula of fistulas were shown in three ca[...]
Conclusion: Four-dimension dynamic imaging by the 640-slice MDCT is a new choice of imaging exam for urine flow related disease, and can directly and clearly show direction and route of urine flow, and provide detail and rich information for diagnosis.
