A 30-year-old woman reports recurrent lower abdominal pain and dysuria, especially around her period. Urinalysis and cultures are negative. What might be the cause?
This patient may have bladder endometriosis, given the cyclical nature of her urinary symptoms and negative urinalysis and cultures. Diagnosis would typically involve imaging such as ultrasound or MRI, and possibly cystoscopy. Treatment includes hormonal therapy and, in severe cases, surgery.
