What are common signs of urinary retention?

The correct response identifies the common signs associated with urinary retention, which typically includes a distended bladder, difficulty starting urination, and dribbling.

A distended bladder occurs when there is an accumulation of urine, signaling that the bladder is unable to fully empty. This can lead to discomfort and visible swelling in the lower abdomen. Difficulty initiating urination is a key symptom because individuals experiencing urinary retention often struggle to start the flow of urine despite an urge to go, attributed to either blockage or other underlying issues. Dribbling may occur as a small amount of urine escapes due to overflow, despite the urinary retention.

In contrast, the other options highlight symptoms that may not directly relate to urinary retention. Frequent urination and urgency suggest a condition like overactive bladder rather than retention. Low urine output might indicate kidney issues or dehydration rather than the retention of urine specifically, while fever tends to suggest infection, which is not a typical indicator of retention itself. Pain during urination and hematuria (blood in urine) are signs that could suggest infections or injuries in the urinary tract but are not specifically connected to urinary retention.
