Urinary Tract Obstruction and Infection

  • Parvati Ramchandani
  • Julia R. Fielding


Imaging plays an important role in the evaluation of patients with acute and chronic urinary tract obstruction. The cause of obstruction varies greatly with the patient population and the geographic locale. In a series reporting on percutaneous nephrostomy drainage, urinary obstruction was related to calculus disease in 26% of patients and to malignancy in 61%. Carcinoma of the bladder, cervix, and colon were the most common primaries in patients with malignancies and urinary obstruction [1].
