Diagnosis Checklist: Questions your doctor may ask (and why!)

During a consultation, your doctor will use various techniques in their assessment of Blood in urine. Your doctor may ask several questions when assessing your condition. It is important to remember that your consultation is a two-way process and any extra information you can share with your doctor about your symptoms may help them with their diagnosis. Some of the questions your doctor may ask are listed below:

• How long have you had blood in the urine? - can determine if acute or chronic.
• Does the blood in the urine occur in the first or the terminal part of the urine stream? - blood in the first part of the urine stream suggests a urethral or Prostatic lesion , while blood in the terminal part of the urine stream suggests bleeding from the bladder. Uniform bleeding has no localizing features.
• Have you had an injury such as a blow to the loin, pelvis or genital area?
• Is the blood in the urine transient or constant? - e.g. joggers and athletes engaged in very vigorous exercise can develop transient blood in the urine.
