Abstract:
Objective To study the image examination of renal injuries and discuss renal explorative indications so as to spare the kidney or nephron as much as possible and improve curative rate of diagnosis and treatment. Methods An analysis was done on 286 cases that included 231 cases with close injury, 54 with open injuries, one with iatrogenic injury and 91 with combined injuries. Of all, 212 cases were examined by B-ultrasonography, 163 by CT and 132 by intravenous urography(IVU) and 6 by digital subtraction angiography(DSA); 202 cases were treated with conservative treatment and 84 with operation. Results The diagnostic positive rates of IVU, B-ultrasonography and CT were 67.4%, 72.2% and 87.7%, respectively. Among the operation cases, 42 cases were treated by renal repair, 12 by partial nephrectomy and 30 by nephrectomy. The operation rate was 29.4% and the nephrectomy rate 35.5%. Interventional treatment of the kidney was carried out in three cases. Conclusions For renal injury cases, the first and most important step is to evaluate the injury condition so as to correctly determine whether an operation exploration is needed. The injury conditions and severity are mainly determined by the image examinations that change according to injury cause, injury type and clinical symptoms. Renal exploration or not, and the operation time exert great influence on renal reservation rate and complication rate.
