ABSTRACT
Subjeet: Twenty patients exposed to renal trauma [all of blunt type] were evaluated by CT aiming to detect and grade the sequelae of such trauma as a primary step for the planning of their management. Study Clinical data, vital signs, urinalysis and blood chemistry [blood urea and serum creatinine] were considered. Screening by ultrasound followed by pre and post- contrast helical abdominal CT were done [30 cm tissue scanned in a single 30 second breath hold]. Plain films after CT were taken as a limited intravenous urographie study [IVU]. CT grading was established and treatment was planned for accordingly. Resuit: The age group ranged from 4-50 years, 50% [10 cases] were below 10 years. Grade I was seen in one case [5%], grade II in 4 cases [20%], grade III in 11 cases [55%.]. and grade IV was in 4 cases [20%]. Grade V [pedicle injury] was not encountered in the present siudy. The accuracy of CT in deteciing sequelae of renal trauma was 100%. With referral to CT, scanning by US was accurate in 90% of cases [2 cases-10% were not conclusive]. Grade I and II were treated conservatively while grade III and IV underwent exploration and surgical repair. CT is a safe, non-invasive modality in detecting and grading sequelae of renal trauma. It was found sensitive in clear delineation of parenchymal laceration, detecting urinary exrtavasation, evaluating the size and extent of hematoma and outlining non-viable tissues
