Abstract Objective：To explore the application value of multi-slice spiral CT in urinary system of threedimensional imaging.Method：The quasi on plain MSCTU scan， enhancement， delayed scanning in 106 cases of urinary system disease patients in our hospital were retrospectively sorting，the original data were analyzed using surface recombination method（ CPR）， maximum intensity projection（ MIP）， multi planar reconstruction（ MPR） and volume rendering（ VR） and other 3D reconstruction methods.Result：MSCTU urinary tract imaging can clearly display the urinary system， also showed a correlation between urinary system and nearby structures and organs.In 106 cases，71 cases of urinary calculi were detected， including 35 cases of renal calculi， 20 cases of ureteral calculi， 16 cases of renal and ureteral multiple stones； and congenital malformation in 7 cases， including 3 cases of double renal pelvis and double ureter， 2 cases of megaureter， ureter cyst cases L and 1 cases of horse hoof shaped kidney； renal cysts in 4 cases，including 2 cases of unilateral cyst， 2 cases of bilateral cyst； kidney， ureter， bladder tumor in 14 cases， including 4 cases of renal cell carcinoma， 5 cases of ureteral carcinoma and 5 cases of bladder cancer； 3 cases of kidney trauma， renal hematoma； ureteral stenosis in 7 cases.Conclusion：MSCTU scan time is short， the image quality is good， the threedimensional image can be obtained at different levels， from different angles， can be a good show urinary system disease location， morphology， anatomy， adjacent relations， the blood supply and properties for diagnosis and clinical treatment of diseases of the urinary system has the unique value in clinical application.
