13.21 Urine sampling: midstream specimen of urine: male
Essential equipment
- Personal protective equipment
- Cleaning solution (e.g. soap and water, 0.9% sodium chloride or disinfectant‐free solution)
- Sterile specimen container with wide opening (CE marked)
- Appropriate documentation/forms
Pre‐procedure
ActionRationale
- 1.
Introduce yourself to the patient, explain and discuss the procedure with them, and gain their consent to proceed.To ensure that the patient feels at ease, understands the procedure and gives their valid consent (NMC [165], C).
- 2.Fully explain the steps of the procedure.The patient needs to fully understand the procedure in order to avoid inadvertent contamination of the specimen and optimize the quality of the sample (Higgins [85], E).
- 3.Ensure a suitable private location.To maintain patient privacy and dignity. E
Procedure
- 4.Ask patient to wash hands with soap and water.To reduce the risk of cross‐infection (NHS England and NHSI [155], C).
- 5.If practitioner's assistance is required: wash hands with bactericidal soap or decontaminate physically clean hands with alcohol rub and put on apron.To prevent cross‐contamination (NHS England and NHSI [155], C).
- 6.Ask patient to retract the foreskin and clean the skin surrounding the urethral meatus with soap and water, 0.9% sodium chloride or a disinfectant‐free solution.To optimize general cleansing and minimize contamination of the specimen with other organisms. EDisinfectant solutions may irritate the urethral mucous membrane (Higgins [84], E).
- 7.Ask patient to begin voiding first stream of urine (approx. 15–30 mL) into a urinal, toilet or bedpan.To commence the flow of urine and avoid contamination of the specimen with naturally occurring micro‐organisms and/or flora within the urethra (PHE [190], C).
- 8.Place the wide‐necked sterile container into the urine stream without interrupting the flow.To prevent contamination of the specimen and ensure the collection of the midstream urine, which most accurately represents the urine in the bladder (PHE [190], C).
- 9.Ask the patient to void his remaining urine into the urinal, toilet or bedpan.For patient to comfortably continue passing urine (PHE [190], C).
- 10.Allow patient to wash hands.To maintain personal hygiene. E
Post‐procedure
- 11.Label sample immediately and complete microbiological request form (including relevant clinical information, such as signs and symptoms of infection, and antibiotic therapy).
- 12.Dispatch sample to laboratory immediately (within 4 hours) or refrigerate at 4°C.To ensure the best possible conditions for microbiological analysis and to prevent micro‐organism proliferation (PHE [190], C).
- 13.Document the procedure in the patient's records.To ensure timely and accurate record keeping (NMC [165], C).
