Name of the Procedure:

Aspiration of Bladder by Needle
Common names: Bladder Aspiration, Suprapubic Aspiration
Technical term: Suprapubic Cystostomy

Summary

Bladder Aspiration by Needle is a minimally invasive procedure where a needle is inserted through the abdomen into the bladder to drain urine. This can also be used to collect a sterile urine sample.

Purpose

This procedure is used to relieve urinary retention, obtain sterile urine samples for testing, or decompress the bladder in certain medical conditions. The goals include alleviating discomfort, preventing urinary tract infections, and enabling accurate diagnoses.

Indications

• Acute or chronic urinary retention
• Need for a sterile urine sample for diagnostic tests
• Bladder obstruction due to an enlarged prostate or urethral stricture
• Certain neurological conditions affecting bladder control

Preparation

• Patients may be asked to empty their bladder partially, if possible.
• No fasting is typically required.
• Discontinue blood thinners or antiplatelet medications as advised by the doctor.
• Pre-procedure ultrasound may be performed to assess bladder fullness and position.

Procedure Description

1. The patient lies supine (face-up) on an examination table.
2. The skin above the pubic bone is cleaned with an antiseptic solution.
3. Local anesthesia is applied to numb the area.
4. Using sterile technique, a small-gauge needle is inserted through the abdominal wall into the bladder.
5. Urine is aspirated into a syringe or allowed to drain through tubing.
6. Once the required amount of urine is collected or the bladder is adequately drained, the needle is removed.
7. A sterile bandage is applied to the needle site.

Duration

The procedure typically takes about 10-20 minutes.

Setting

Bladder Aspiration by Needle is usually performed in a hospital, outpatient clinic, or a doctor’s office.

Personnel

• Primary practitioner: Urologist or trained healthcare professional
• Assisting staff: Nurse or medical assistant

Risks and Complications

• Infection at the puncture site
• Bleeding or hematoma formation
• Injury to surrounding organs or structures, though rare
• Pain or discomfort at the insertion site
• Urine leakage or fistula formation, very rarely

Benefits

• Immediate relief from urinary retention
• Accurate collection of sterile urine for diagnostic purposes
• Minimally invasive with a quick recovery time
• Early detection of any underlying abnormalities

Recovery

• Keep the area clean and dry.
• Avoid strenuous activities for 24 hours.
• Monitor for signs of infection such as redness, swelling, or fever.
• Follow-up appointments as needed for underlying conditions.

Alternatives

• Urethral catheterization: Inserting a tube through the urethra to drain urine, which might be less invasive but carries risks of infection.
• Indwelling suprapubic catheter: For long-term needs, a more permanent catheter placed under a minor surgical procedure.
• Medications or surgery: Treating the underlying cause of urinary retention if applicable.

Patient Experience

• During the procedure: Mild discomfort or pressure may be felt, but pain is minimized with local anesthesia.
• After the procedure: Slight soreness at the needle site; pain relief is typically manageable with over-the-counter analgesics.
• Reassurance and clear communication from the healthcare team help ensure patient comfort and peace of mind.
