Name of the Procedure:

Common Name(s): Urine Culture
Technical Term: Culture, Bacterial, Urine; Quantitative, Sensitivity Study (P7001)

Summary

A urine culture is a test that detects and identifies bacteria in the urine. The procedure involves taking a urine sample and growing bacteria in a lab to determine the type and amount of bacteria present, as well as their sensitivity to antibiotics.

Purpose

This procedure is primarily used to diagnose urinary tract infections (UTIs). It helps healthcare providers determine the specific bacteria causing the infection and identify the most effective antibiotics for treatment.

Indications

• Symptoms of a UTI such as frequent urination, burning sensation during urination, and cloudy or strong-smelling urine.
• Recurrent UTIs.
• Persistent symptoms even after treatment.

Preparation

• There are generally no specific preparations like fasting required.
• Patients may be instructed to collect a midstream urine sample to avoid contamination.
• Sometimes, cleaning the genital area before providing a sample is recommended.
• Patients should inform their doctor about any medications they are currently taking, as some might interfere with the results.

Procedure Description

1. Collection of Urine Sample:
   • The patient collects a midstream urine sample in a sterile container.
2. Lab Analysis:
   • The urine sample is sent to a lab, where it is placed in culture dishes.
   • The dishes are incubated to allow bacterial growth.
3. Quantitative and Sensitivity Study:
   • Once bacterial growth is observed, the bacteria are counted to determine the severity of the infection.
   • Further tests identify which antibiotics the bacteria are sensitive or resistant to.

Duration

• Collecting the urine sample takes a few minutes.
• Lab analysis and culture growth typically take 24 to 48 hours.

Setting

• The urine sample is usually collected in a doctor's office, clinic, or at home (if given a sterile container and instructions).
• The analysis is performed in a specialized lab.

Personnel

• Physicians or nurses may provide instructions for sample collection.
• Medical laboratory technicians and microbiologists conduct the analysis.

Risks and Complications

• Generally, there are no risks associated with providing a urine sample.
• Contaminated samples could lead to inaccurate results, possibly requiring repeat testing.

Benefits

• Accurate diagnosis of the specific bacteria causing the infection.
• Identification of the most effective antibiotic treatment.
• Improved management of UTIs and reduced risk of complications from untreated infections.

Recovery

• There is no recovery period for the test itself.
• Patients should follow up with their healthcare provider to discuss test results and treatment options.

Alternatives

• Dipstick tests or urinalysis for initial UTI screening.
• Imaging tests like ultrasound if structural issues are suspected.
• Empiric antibiotic treatment based on symptoms and medical history, without culture confirmation.

Patient Experience

• The patient may feel minimal discomfort during the collection of the urine sample.
• No pain or significant discomfort is associated with the procedure itself.
• Results typically take 1-2 days, during which time patients may continue experiencing UTI symptoms. Pain management and symptomatic relief may be provided by the healthcare provider in the interim.
