Which is a common postoperative complication after urologic surgery?
a. Joint pain
b. Wound dehiscence
c. Headache
d. Oliguria
ANS: D
Oliguria, the diminished capacity to form urine, occurs because the hormones secreted during the procedure (antidiuretic hormone, aldosterone, epinephrine, and norepinephrine) conserve water and sodium. This decreases urinary output. Also, dehydration, shock, cardiac failure, and third-space loss contribute to oliguria.
