Abstract

Magnetic resonance imaging (MRI) is evolving as an imaging modality for the urinary tract that offers not only superior anatomic but also functional assessment, without the use of ionizing radiation. This comprehensive evaluation of the urinary tract allows for diagnosis of numerous urologic anomalies including ureteropelvic junction obstruction, duplication anomalies, ectopic ureters, and megaureters. Parameters obtained during magnetic resonance urography such as differential renal function, calyceal, and renal transit time help aid in decision making regarding surgical and medical management of these various urologic conditions. This chapter will discuss the technique of magnetic resonance urography (MRU), as well as clinical applications. While MRU is currently more commonly used in cases where conventional imaging modalities fail to fully define complex urologic anatomy and function, it has the potential to become the preferred first-line radiologic study.
