[Diagnosis and treatment of blunt renal injury].

157 renal injury cases (22.2%) of 708 blunt abdominal injury cases admitted at our hospital from January, 1981 to April, 1991 were evaluated. The results suggested that large dose IVP have certain limitations, while modern ultrasound findings have important practical value. We think that the patients with renal injury more than 3 degree must be operated immediately. Nephrectomy may be considered on injured kidney if the contralateral renal function is normal, in order to avoid late complications. In cases of using inosine, dopamine and large furosemide during operation, the time lag of indicamine presenting in urine is helpful for judging and protecting contralateral renal function.
