Name of the Procedure:

Urinalysis; 2 or 3 Glass Test
Also known as: Prostate massage test, 2-glass test, 3-glass test

Summary

The 2 or 3 glass test is a specialized type of urinalysis used to diagnose prostatitis and other urinary tract conditions. The test involves collecting urine samples before and after a prostate massage to detect infections and inflammation.

Purpose

The primary goal of the 2 or 3 glass test is to identify and differentiate between prostatitis, urethritis, and other infections in the lower urinary tract. It helps determine the presence and location of infection or inflammation.

Indications

• Symptoms such as frequent urination, painful urination, and pelvic pain
• Suspected prostatitis
• Recurrent urinary tract infections
• Inflammatory conditions of the urethra and prostate

Preparation

• Patients may need to abstain from ejaculation for 2-3 days before the test.
• No specific fasting required.
• Inform the doctor about any medications being taken to avoid interference with test results.
• Drink plenty of fluids the day before the procedure.

Procedure Description

1. First Sample Collection: The patient provides a urine sample before a prostate massage.
2. Prostate Massage: A healthcare professional performs a digital rectal exam (DRE) and massages the prostate gland to release prostatic fluid.
3. Second Sample Collection: Depending on the test, the patient provides one or two additional urine samples immediately after the prostate massage.
4. Samples are sent to a laboratory for analysis to check for white blood cells, bacteria, and other indicators of infection.

Tools and Equipment

• Sterile urine collection containers
• Gloves and lubricant for the prostate massage
• Lab equipment for urinalysis

Anesthesia or Sedation

• Generally, no anesthesia or sedation is required as the procedure is relatively quick and minimally invasive.

Duration

The entire procedure typically takes about 15-30 minutes.

Setting

This procedure is usually performed in a doctor's office or outpatient clinic.

Personnel

• Urologist or primary care physician
• Nurse or medical assistant may assist with sample collection and processing

Risks and Complications

• Mild discomfort or pain during the prostate massage
• Slight risk of urinary tract infection
• Rarely, blood in the urine after the procedure

Benefits

• Accurate diagnosis of infections and differentiates the location and type of inflammation
• Helps tailor appropriate antibiotic or other treatments
• Provides immediate and valuable information to manage symptoms effectively

Recovery

• Patients can usually resume normal activities immediately after the procedure.
• Pain or discomfort, if any, is generally mild and temporary.
• Drink plenty of fluids and follow any additional instructions given by the healthcare provider.

Alternatives

• Simple urine culture without prostate massage
• Blood tests to check for infection markers
• Imaging studies like ultrasound or MRI
• Each alternative has varying levels of accuracy and may not be as specific in identifying prostatitis.

Patient Experience

During the procedure, patients might feel mild discomfort or pressure during the prostate massage. After the procedure, some patients may notice temporary mild soreness or slight blood in the urine, which usually resolves quickly. Pain management is typically not required, but over-the-counter pain relief can be used if necessary.
