The comparative study between the 64-slice spiral computed tomography urography and intravenous urography

Objective To evaluate of the clinical application of the 64-slice spiral computed tomography urography(CTU) and intravenous urography(IVU).Methods The intravenous urography and 64-slice spiral computed tomography urography of 130 patients with clinically suspected urinary system disease were comparative ustudied.Raw CT data were reconstructed by reconstruction processing work station.Results In IVU,3 patients were normal and in CTU,2 patients were normal.Urolithiasis were found in 95 patients by IVU,kidney stones in 50 cases,ureteral calculus in 44 cases,vesical calculus in 1 case,2 cases ureteral outside pressed,malformation in 6 cases,tumour in 7 cases,infective in 1 case.Urolithiasis were found in 106 patients by CTU,kidney stones in 60 cases,ureteral calculus in 45 cases,vesical calculus in 1 case,in 4 cases ureteral outside pressed,malformation in 9 cases,tumour in 20 cases,infection in 17 cases.It had not statistical difference between the two methods to urinary calculi,deformity(P0.05),but for infection,tumor had statistical difference(P0.05).Conclusion 64-slice spiral computed tomography urography through a variety of post-processing method can show the panoramic urinary morphological structure,also,can observe local lesion details,play an important role in clinical diagnosis;And IVU can be used for urinary obstruction by simple stone.
