For the examination of prostatitis, the main methods currently used are color ultrasound, routine prostate fluid analysis, culture of prostate fluid, and susceptibility testing. After contracting prostatitis, a color ultrasound examination often reveals varying degrees of prostate swelling, routine prostate fluid analysis will indicate a decrease in lecithin bodies, accompanied by either an increase in white blood cells or normal white blood cell levels. If the lecithin bodies are decreased and there is an increase in white blood cells, bacterial prostatitis is a likely consideration. If the white blood cell count is normal, nonbacterial prostatitis may be considered. Regardless of the type of prostatitis, timely examination and treatment are necessary. If it is bacterial prostatitis, further culture and susceptibility testing of the prostate fluid should be performed, and treatment should be conducted using antibiotics that are sensitive to the results of the susceptibility test.
