Which of the following symptoms is associated with kidney stones?

Hematuria, or the presence of blood in the urine, is a common symptom associated with kidney stones. As kidney stones pass through the urinary tract, they can irritate the lining of the ureters or the bladder, leading to bleeding. This bleeding results in the characteristic red or brown discoloration of urine, which is a key indicator for possible kidney stones.

In contrast, jaundice is typically related to liver dysfunction or bile duct obstruction, not directly to kidney stones. A persistent cough is more indicative of respiratory issues, while fever might suggest an infection or inflammation, which could be secondary to complications from kidney stones but is not a primary symptom of the stones themselves. Thus, hematuria is the primary symptom directly associated with the presence of kidney stones.
