Fast Five Quiz: Overactive Bladder Differential Diagnosis

Bradley Schwartz, DO

These are most likely symptoms of UTI. The classic symptoms of UTI in adults are primarily dysuria with accompanying urinary urgency and frequency. A sensation of bladder fullness or lower abdominal discomfort is often present. Bloody urine is reported in as many as 10% of cases of UTI in otherwise healthy women; this condition is called hemorrhagic cystitis.

Because blood in the urine is not a common symptom of OAB, this condition can be ruled out. Because this patient is female, benign prostatic hyperplasia can also be ruled out.

Vaginitis is a very common gynecologic condition that generally includes symptoms of abnormal discharge, vulvovaginal discomfort, or both.

Pregnancy is often accompanied by bothersome urinary symptoms, including nocturia, urgency, daytime frequency, and painful bladder. However, blood in the urine should be considered a symptom of UTI and not pregnancy.
