This study will look at how well a measure called the Qmax/eGFR ratio is related to the severity of urination problems in men over the age of 40. Qmax is a test that shows how fast a person can urinate, and eGFR is a number that reflects kidney function. Men who have urinary symptoms will be asked to do a urine flow test, a blood test, and fill out a questionnaire about their symptoms and quality of life. We will study if there is a link between the Qmax/eGFR ratio and how severe their symptoms are. The results may help doctors better understand how kidney and urinary function are related in men with these problems.
