Magnetresonanzurographie in der Kinderurologie

Abstract

Magnetic resonance urography (MRU) provides high resolution imaging of the urogenital system and the use of paramagnetic contrast agents enables a functional depiction. This review summarizes existing data concerning this diagnostic procedure in pediatric urology. A systematic search and assessment of the literature was performed.A total of 12 studies were reviewed in detail. In mostly small study populations a great heterogeneity concerning methodology, use of comparative examinations and standards of reference was noted. Besides the quality of anatomical imaging, the functional study of renal excretory function and differential renal function was also assessed. Only a few studies performed statistical analyses.The authors' rating of MRU was mostly positive. Due to methodical weaknesses, lack of independent standards of reference and statistical analyses the overall level of evidence was low. Further high quality studies will be necessary to assess the value of MRU for the diagnostic workup in pediatric urology.

Onkologische Erkrankungen und postoperative Veränderungen der Harnblase und der ableitenden Harnwege

“…Die MRT wird als strahlungsfreie Modalität idealerweise bei jungen Patienten bzw. Kindern und Schwangeren eingesetzt, wobei hier typischerweise Anlagevarianten der oberen Harnwege [13, 14,15] bzw. Konkremente in den harnableitenden Wegen [16,17,18] im Fokus stehen und eine Malignomabklärung der harnableitenden Wege seltener die primäre Fragestellung ist.…”
