However it is unknown whether AE preserves renal function because conventional renal function tests reflect total renal function and not the function of the injured kidney alone. Dynamic scintigraphy can assess differential renal function. Methods We performed AE in 17 patients with grade-4 blunt renal trauma and determined their serum creatinine sCr level and glomerular filtration rate GFR estimated by dynamic scintigraphy after 3 months. In 4 patients with low GFR of the injured kidney 20 ml-min-1-1.73 m-2 the GFR and sCr were measured again at 6 months. Data are presented as median and interquartile range 25th 75th percentile . Results The median GFR of the injured kidney total GFR and median sCr at 3 months were 29.3 23.7 35.3 and 96.8 79.1 102.6 ml-min-1-1.73 m-2 and 0.6 0.5 0.7 mg dl respectively. In the patients with low GFR ml-min-1-1.73 m-2 the median GFR of the injured kidney total GFR and median sCr mg dl were 16.2 15.7 16.3 68.7 61.1 71.6 and 0.7 0.7 0.9 respectively at 3 months and 34.5 29.2 37.0 90.9 79.1 98.8 and 0.7 0.7 0.8 respectively at 6 months. Conclusions The function of the injured kidney was preserved in all patients indicating the efficacy of AE for the treatment of grade-4 blunt renal trauma. Background Some recent studies have suggested that high-grade renal trauma can be successfully treated by non-opera-tive management NOM which includes .
