Introduction
A cystometrogram (CMG) is a specialized urodynamic test used to measure bladder pressure and function during filling and emptying. This diagnostic tool helps identify issues such as overactive bladder, urinary retention, or incontinence. At Crossroads Urology, we perform CMG studies to provide detailed insights into bladder health and develop tailored treatment plans.
Purpose
A cystometrogram is used to:
- Diagnose overactive bladder, bladder outlet obstruction, or neurogenic bladder.
- Evaluate the cause of urinary incontinence or retention.
- Assess bladder compliance, capacity, and sensation.
- Guide treatment planning for bladder-related conditions.
Procedure
During the CMG test:
- A small catheter is inserted into the bladder to measure pressure and fill the bladder with sterile fluid.
- Another catheter is placed in the rectum or vagina to monitor abdominal pressure.
- The patient is asked to report sensations (e.g., fullness, urge to urinate) as the bladder fills.
- Bladder function and pressure readings are recorded throughout the filling and voiding process.
The test typically takes 30-45 minutes and is performed in-office.
Preparation
- Patients may be asked to arrive with a full bladder for preliminary testing.
- Avoid caffeinated or carbonated drinks before the procedure.
- Inform the provider of any urinary infections, as these may delay the test.
Risks and Considerations
CMG is safe, but potential risks include:
- Temporary discomfort during catheter insertion.
- Rare urinary tract infections.
At Crossroads Urology, we take measures to ensure patient comfort and minimize risks during the procedure.
Results
- The results provide valuable information about bladder pressure, capacity, and responsiveness.
- Findings are reviewed with the patient, and a personalized treatment plan is developed based on the diagnosis.
Conclusion
A cystometrogram is a vital diagnostic tool for understanding bladder function and addressing complex urinary issues. At Crossroads Urology, we combine expert care with advanced diagnostics to deliver the best outcomes for our patients. Contact us today to learn more about CMG testing and schedule your evaluation.
