Abstract:
Objective To evaluate the value of non-enhanced MSCT (NMSCT) ureteral reconstruction combined with renal hemodynamics in the diagnosis of ureteral calculi. Methods Patients (162 cases) with primary diagnosis of ureteral calculi were scanned with NMSCT and radionuclide renal dynamic imaging. The clinical data were analyzed retrospectively. Results Patients with ureteral calculi ( 102 cases) and of non- ureteral calculi ( 60 cases) were diagnosed definitely. The average width of calculi was ( 7 . 6 ± 2 . 8 ) mm. The sensitivity and specificity of NMSCT in the diagnosis of ureteral calculi were 88.2% and 91.7%, respectively. The sensitivity and speci?city of renal hemodynamics were 83.3% and 88.3%, respectively. The highest sensitivity and speci?city of NMSCT combined with renal hemodynamics in the diagnosis of ureteral calculi were 92.2% and 93.3%. NMSCT showed hydronephrosis in patients with ureteral calculi, and to some extent, could indicate the severity of urinary obstruction (renal function) shown by renal ?ow chart. Conclusion NMSCT ureteral reconstruction can obtain good urography and display ureteral calculi accurately and clearly. The diagnosis of ureteral calculi and evaluation of renal function can be accomplished by combining NMSCT with renal blood ?ow imaging. It has important value for clinical diagnosis and treatment, and can replace traditional CTU examination.
