Which symptom might indicate a urinary obstruction?

Difficulty starting urine flow is a key indicator of urinary obstruction. This symptom often arises when there is a blockage in the urinary tract that prevents urine from flowing freely from the bladder or through the urethra. Such obstructions can occur due to various reasons, including enlarged prostate, urinary stones, or strictures. As a result, individuals may experience increased strain or effort while trying to initiate urination, which indicates a potential obstruction in the urinary pathway.

Frequent urination without pain, painful urination, and urgency to urinate can be associated with various urinary conditions but do not specifically indicate an obstruction. Frequent urination may occur in cases of overactive bladder or urinary tract infections, while urgency can stem from similar causes. Painful urination usually signals inflammation or irritation but doesn't necessarily denote an obstruction. Thus, difficulty starting urine flow is a more direct symptom suggesting a mechanical interference in the urinary system.
