Obstructive uropathy is defined as a structural or functional restriction of urinary flow, which if left uncorrected will lead to impairment of renal function. There are numerous radiologic signs that suggest and help define genitourinary obstruction. This chapter aims to describe the imaging modalities and findings used to characterize and diagnose genitourinary obstruction in specific pathologic entities.
