Summary
Brief summary (as posted)
RATIONALE: New diagnostic procedures such as microsatellite analysis of sediment in the urine may improve the ability to detect bladder cancer without invasive procedures. PURPOSE: Diagnostic trial to study the effectiveness of microsatellite analysis of sediment in the urine in detecting bladder cancer in healthy participants, participants who have genitourinary conditions requiring cystoscopy, and patients who have bladder cancer.
