Question

A pt with high blood pressure undergoes renography followed by captopril renography, and the curve of renal uptake from the second exam is lower than the first. What does this mean? The patient:

a. is rejecting a transplanted kidney
b. has renovascular htn
c. has an obstruction in the collecting system
d. has high blood pressure
e. none of the above

Answer 1

A decrease in renal uptake during captopril renography suggests renovascular hypertension, a condition characterized by reduced blood flow to the kidneys and high blood pressure.

Step-by-step explanation:

When a patient with high blood pressure undergoes renography followed by captopril renography, and the curve of renal uptake from the second exam is lower than the first, it suggests that the patient has renovascular hypertension. Renovascular hypertension is a condition where there is reduced blood flow to the kidneys, leading to high blood pressure. The lower uptake in the second exam indicates decreased blood flow to the kidneys and impaired renal function, which is commonly seen in renovascular hypertension.
