Urinary Tract Obstruction and Infection

  • Parvati Ramchandani
  • Harriet C. Thoeny


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.
