A routine urinalysis cannot determine prostatitis. It can, however, rule out other urinary system infections such as urethritis or cystitis through routine urinalysis. If the urinalysis is normal but the patient still exhibits symptoms like frequent urination, urgency, and incomplete emptying of the bladder, this may indirectly suggest the possibility of prostatitis. In cases of acute bacterial prostatitis, the urinalysis may show varying degrees of increased white blood cells. To confirm prostatitis, it is best to examine the prostate fluid for lecithin corpuscles and white blood cells.
