title: [Multidetector computed tomography of urolithiasis: technique and results].
abstract: The diagnosis of acute urolithiasis results from unenhanced multidetector computed tomography (MDCT). This test analyses the functional and anatomical possibility for passing an ureteral calculi, the localization and dimension of which are important parameters for further therapy. Alternatively chronic urolithiasis could be ruled out by magnetic resonance urography (MRU). MRU is the first choice especially in pregnant women and children because of radiation hygiene. Enhanced MDCT must be emphasized as an alternative to intravenous urography (IVU) for diagnosis of complex drainage of urine and suspected disorder of the involved kidney. This review illustrates the principles of different tests and the clinical relevance thereof.
