Which sign may indicate the presence of kidney stones?

The presence of kidney stones is often indicated by pink or brown urine. This discoloration can occur due to the presence of blood in the urine, known as hematuria, which is a common symptom associated with kidney stones. When stones pass through the urinary tract, they can irritate the lining of the urinary system, leading to bleeding. This is why observing darker shades of urine, such as pink or brown, can be a significant clue in identifying kidney stones.

Frequent urination in large amounts, although a urinary symptom, is not directly indicative of kidney stones and may be associated with other issues such as diabetes or urinary tract infections. Hearing loss and loss of appetite are symptoms that do not correlate with kidney stone formation and are more often linked to different medical conditions. Thus, the presence of pink or brown urine is a key sign that prompts further investigation into the possibility of kidney stones.
