Final answer:
Renal arterial bruits in the abdomen, flanks, or back are suggestive of renovascular hypertension.
Step-by-step explanation:
The finding suggestive of renovascular hypertension is renal arterial bruits in the abdomen, flanks, or back. Renovascular hypertension is a condition in which there is narrowing or blockage of the renal arteries, leading to increased blood pressure. The presence of renal arterial bruits indicates turbulent blood flow in the arteries and is often associated with renovascular hypertension. Bilateral flank pain on percussion, a palpable mass in the right lower quadrant, and decreased urine output are not specific findings for renovascular hypertension.
