Emergency uroradiology for the nontraumatized patient

Emergency uroradiology is warranted in a number of clinical conditions in the nontraumatized patient in order to determine proper therapeutic management. Among such urgent conditions are: severe gross hematuria, severe internal blood loss with possible origin in the urinary tract, acute renal artery obstruction, major extravasation of urine, severe sepsis possibly from the urinary tract, anuria, and obstructive uropathy with superimposed infection.
