Which review of systems includes symptoms like painful urination and flank pain?

The review of systems that includes symptoms such as painful urination and flank pain is the genitourinary system. This system encompasses the organs involved in the production, storage, and elimination of urine, as well as the reproductive organs. Painful urination, often referred to as dysuria, and flank pain, which can indicate issues with the kidneys or urinary tract, are both directly related to the functioning and health of the genitourinary organs.

The gastrointestinal system is primarily concerned with digestive tract issues, including symptoms like abdominal pain and changes in bowel habits. The respiratory system covers symptoms associated with breathing and lung function, such as coughing or shortness of breath. The constitutional review of systems typically addresses general health, including symptoms like fever, weight loss, or fatigue that do not specifically relate to the urinary or reproductive systems. Therefore, the symptoms in question align directly with the genitourinary system, confirming it as the correct choice.
