Which symptom is classic for ureterolithiasis?

Renal colic is the classic symptom associated with ureterolithiasis, which refers to the presence of stones in the ureter. This condition typically presents with severe, intermittent flank pain that may radiate to the lower abdomen and groin. Renal colic occurs as the stone obstructs the flow of urine, causing increased pressure in the urinary system and stimulating the visceral nerves. The pain can be intense and is often described as one of the most severe types of pain.

The presentation of renal colic is distinct because it usually comes in waves and may be accompanied by other symptoms such as nausea or hematuria. The precise location of pain can help differentiate renal colic from other conditions, making it a hallmark symptom of ureterolithiasis.

Other symptoms mentioned, such as abdominal distension, fever, or bone pain, do not specifically characterize ureterolithiasis. Abdominal distension may indicate other gastrointestinal issues, fever could suggest an infection, and bone pain is unrelated to the urinary tract system. Thus, renal colic remains the defining symptom for diagnosing ureterolithiasis effectively.
