Abstract
Imaging plays an important role in evaluating patients with both acute and chronic urinary tract obstruction. The cause of obstruction varies greatly with patient population and geographic locale. In a series reporting on percutaneous nephrostomy drainage, urinary obstruction was related to calculus disease in 26% of patients and malignancy in 61%. Carcinoma of the bladder, cervix, and colon were the most common primaries in patients with malignancies and urinary obstruction [1]. Enlarged retroperitoneal and pelvic lymph nodes due to various malignancies, including lymphoma and testicular cancer, can also lead to secondary obstruction.
