There are many types of bacterial prostatitis, including bacterial bacterial prostatitis, non-bacterial bacterial bacterial prostatitis, etc. The type needs to be determined before treatment. Urinary four-cup test is one of the common methods to determine the type of bacterial prostatitis, and also the "gold standard" for diagnosis of bacterial prostatitis. It has the advantages of simple operation, no damage to patients and low cost.
Urine four-cup method refers to collecting urine or bacterial prostatitis of patients suspected of bacterial prostatitis in stages for bacterial culture, bacterial count and routine microscopic examination of prostate fluid. The specific steps are as follows: after sterilization of the urethral orifice, collect 10 ml of initial urine; 10 ml of middle urine; Massage the prostate to collect prostate fluid; After prostate massage, 10 ml of initial urine will be put into four sterile tubes for the above test.
Diagnostic criteria: if there is no bacterial growth in the four samples of the patient, it can be diagnosed as non-bacterial bacterial prostatitis; If there is no bacterial growth in the initial and middle urine, or the number of bacterial growth is less than 3000 per milliliter, and the number of bacterial growth in the initial urine after prostate massage fluid or prostate massage exceeds 1000 per milliliter, it can be diagnosed as bacterial prostatitis; Or if the number of bacteria growing in the middle urine exceeds 1000 per milliliter, it can be diagnosed as cystitis; If the prostate fluid cannot be taken out after prostate massage, it can be diluted by 100 times of the initial urine after prostate massage and then cultured, and the relevant diagnosis can be made according to its bacterial growth.
