1 Method:62 patients with ureterolithiasis were treated with the above mentioned lithotriptor.

2 The ureterolithiasis besides has hematuria, the abdominal pain, but also has frequent micturition , the urgency of urination, is similar in the urinary tract infection symptom.

3 Methods 31 patients with the upper and middle ureterolithiasis under going the operation of ureterolithotomy via the semilunar line incision were reviewed, in combination with related literature.

4 Double side ureterolithiasis were 6 cases, solitary kidney 2 cases and one side renal atrophy and other side ureterolithiasis 2 cases.

5 Objective To evaluate the diagnostic efficacy of the reformatted unenhanecded spiral CT of ureter for ureterolithiasis .

6 Objective To explore the diagnostic value of spiral CT for acute ureterolithiasis .

7 Objective To study the clinical value of B ultrasound in the diagnosis of ureterolithiasis without ipsilateral kidney hydrocele.

8 Results With the low-dose scan, The sensitivity and accuracy rates of the detection of nephrolithiasis and ureterolithiasis on the low-dose scan were 100% and 98% respectively.

9 Conclusion Perinephric edema is a important CT finding of ureteral obstruction in patients with acute ureterolithiasis .

10 Methods Nonenhanced CT images of 28 patients with acute ureterolithiasis were retrospectively analysed.

11 Objective To investigate the therapeutic effects of pneumatic lithotripsy (PL) through ureteroscope in the treatment of ureterolithiasis.

12 Conclusion: The findings of CPR can display the entire course of ureter on a planum and is valuable in diagnosis of ureterolithiasis .

13 Methods Nonenhanced CT images in 73 patients with acute ureterolithiasis were retrospectively reviewed.

14 Conclusion Our findings suggest that the reformatted nonenhanecded spiral CT of ureter has potential as an imaging tool for the ureterolithiasis and other urinary tract abnormalities.

15 Objective: To investigate the value of curved planar reformation (CPR) of unenhanced spiral CT in diagnosis of ureterolithiasis.

16 Objective To comprehend manifestations of CT images in the kidney and the perinephric space with acute ureteral obstruction caused by the ureterolithiasis.
