A 70-year-old man comes to the physician because
of discomfort in his lower abdomen for 1 week. Use of
over-the-counter ibuprofen has not relieved the
symptoms. He has a 25-year history of hypertension
currently treated with quinapril. His pulse is 90/min
and regular, and blood pressure is 140/80 mm Hg. The
lungs are clear to auscultation. Cardiac examination
shows no murmurs or gallops. There is a 7-cm mass
extending superiorly from the symphysis pubis in the
midline. Serum studies show a urea nitrogen (BUN)
concentration of 60 mg/dL and a creatinine
concentration of 4.5 mg/dL. Ultrasonography of the
kidneys shows bilateral hydronephrosis. Which of the
following is the most likely cause of this patient's
laboratory findings?
A. Angiotensin-converting enzyme (ACE) inhibitor
therapy
B. Glomerulonephritis
C. Nonsteroidal anti-inflammatory drug therapy
D. Prerenal azotemia
E. Urethral obstruction
