OBJECTIVE: The purposes of this pictorial essay are to show MDCT findings of renal trauma and describe the indications and protocol for MDCT.
CONCLUSION: CT is indicated when patients have gross hematuria, hypotension, lumbar spinal injury, and fractures of lower ribs or the transverse process. The CT examination must be designed specifically for urinary tract evaluation, and MDCT is especially useful for this purpose. Injury to the kidney is graded I to V according to degree of laceration and amount of hematoma.
