Safely Reduce Cystoscopic Evaluations for Hematuria Patients

This study is looking at whether it is safe to reduce the number of cystoscopy (internal bladder camera) exams for certain patients who have microscopic blood in their urine (called microscopic hematuria). Most of the time, this blood comes from benign causes. Researchers want to know if fewer invasive exams are needed without missing important diagnoses. **You may be eligible if...** - You are a man aged 40 or older, or a woman aged 50 or older - Lab tests have detected at least 3 red blood cells per field in your urine (microscopic hematuria confirmed) **You may NOT be eligible if...** - You have a history of bladder cancer or urinary tract cancer - Your blood in the urine is visible to the naked eye (macroscopic hematuria) - You are or may be pregnant Talk to your doctor to see if this trial is right for you.
