Which is a hallmark symptom of interstitial cystitis?

• A. Pain and pressure in the bladder area lasting 6+ weeks, unrelated to UTI
• B. High fever and flank pain
• C. A single episode of urinary incontinence
• D. Red blood cells in urine

Answer: (A)

The key idea is recognizing the defining pattern of interstitial cystitis: chronic bladder or pelvic pain with pressure that lasts for an extended period and is not due to a urinary infection. The best choice captures both elements—pain and pressure in the bladder area for six weeks or longer, with no infection to explain it—matching how interstitial cystitis presents in many patients.

This condition often includes urgency and frequency as well, but the crucial distinguishing point is the chronic nature of the pain without an infectious cause. In contrast, fever and flank pain point to a kidney or upper urinary tract infection, which is an acute infectious process rather than a chronic pain syndrome. A single episode of incontinence isn’t the persistent bladder pain pattern characteristic of interstitial cystitis, and red blood cells in the urine suggest hematuria from infection, stones, or other conditions, not the hallmark bladder-pain syndrome.
