Simple cystometrogram (CMG) (eg, spinal manometer)
CPT4 code
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
- The patient will lie down and a thin catheter will be gently inserted into the bladder through the urethra.
- The bladder will be slowly filled with a saline solution through the catheter.
- A spinal manometer will be connected to measure bladder pressure at various points during filling and voiding.
- The patient may be asked to cough or bear down to assess bladder and urethral function under different conditions.
- 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.
