Diagnosis of renal trauma]

We experienced 25 cases of renal trauma in our hospitals during the past 5 years, 20 cases were male and 5 cases were female, ranging in age 10 to 51 years old with average 26 years old, and the chief complaints were gross-hematuria and pain of renal region. We studied the IVP and CT patterns of these cases. IVP revealed 13 cases of renal contusion, 11 cases of renal lacerated wound and 1 case of renal fragmentation. The CT scan of 14 cases showed that it was useful for the diagnosis of the degree of renal trauma, especially, for hematoma surroundings the kidneys. The hematoma surrounding the kidneys was clearly noted in 7 cases by CT scan, but the unclearness of renal contours and iliopsoas muscle was considered to suggest the existence of hematoma surrounding the kidneys by IVP. All of the hematoma surrounding the kidneys was absorbed by conservative therapy, but 5 of the 7 cases were treated within 3 months.
