51725 Simple cystometrogram (CMG) (eg, spinal manometer)

Name of the Procedure:

Simple Cystometrogram (CMG)

• Common Name: CMG
• Technical/Medical Term: Cystometry using a spinal manometer

Summary

A Simple Cystometrogram (CMG) is a test that measures the pressure inside the bladder to evaluate its function. It helps determine how well the bladder can hold and release urine.

Purpose

• Medical Condition/Problem: Diagnosis of urinary problems such as incontinence, frequent urination, or difficulty urinating.
• Goals/Outcomes: To assess bladder capacity, detect abnormalities in bladder pressure, and evaluate the coordination between the bladder and urethra during storage and voiding of urine.

Indications

• Symptoms such as frequent urination, urgency, or restricted urine flow.
• Conditions like neurogenic bladder, urinary incontinence, or bladder dysfunction.
• Patients with spinal cord injuries or diseases affecting bladder function.

Preparation

• Pre-Procedure Instructions: Patients should come with a full bladder if instructed; otherwise, no specific preparation required.
• Diagnostic Tests/Assessments: A thorough medical history and physical examination. Other tests like urine analysis may be done prior.

Procedure Description

1. The patient will lie down and a thin catheter will be gently inserted into the bladder through the urethra.
2. The bladder will be slowly filled with a saline solution through the catheter.
3. A spinal manometer will be connected to measure bladder pressure at various points during filling and voiding.
4. The patient may be asked to cough or bear down to assess bladder and urethral function under different conditions.
5. Data collected helps to identify any abnormalities in bladder pressure and function.

• Tools/Equipment: Catheter, spinal manometer, saline solution.
• Anesthesia/Sedation: Typically, no anesthesia or sedation is required.

Duration

The procedure usually takes about 30 to 45 minutes.

Setting

Typically performed in a hospital, urology clinic, or outpatient setting.

Personnel

• Urologist or specialized healthcare provider.
• Assisting nurses or medical technicians.

Risks and Complications

• Common risks: Mild discomfort, minor urethral irritation, or slight bleeding.
• Rare risks: Infection or injury to the bladder or urethra. Possible complications can be managed with appropriate medical care.

Benefits

• Provides critical information about bladder function.
• Helps in diagnosing the cause of urinary symptoms.
• Information from the test can guide effective treatment plans.
• Benefits are generally realized soon after the procedure, aiding in prompt diagnosis and treatment.

Recovery

• Post-Procedure Care: Patients may resume normal activities immediately.
• Recovery Time: Minimal to no recovery time is needed.
• Restrictions/Follow-Up: Follow-up appointments if abnormal results were found, and further treatments are necessary.

Alternatives

• Other Treatment Options: Uroflowmetry, post-void residual measurement, or more advanced urodynamic studies.
• Pros and Cons: CMG is less invasive and simpler than some alternatives but may not provide as comprehensive data as more complex urodynamic tests.

Patient Experience

• During the Procedure: Patients may experience mild discomfort or the urge to urinate but generally well-tolerated.
• After the Procedure: Slight burning during urination may occur, which usually subsides quickly. Pain management typically isn't necessary beyond over-the-counter pain relievers if needed.
