<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, I think I have overflow incontinence. I cant seem to control my urine flow and its constantly leaking.  <response>: Based on your symptoms, I will need to do a few tests to determine the cause of your incontinence. We will start with a urinalysis to evaluate your bladder health. We may also need to perform an ultrasound to measure your bladder capacity and check for any abnormalities. Additionally, I may need to perform a rectal examination to evaluate the tone of your anal sphincter. Finally, we may need to perform an endoscopy and biopsy of the urinary tract to rule out any structural abnormalities.
