Micturating Cystourethrogram (MCUG) is a detailed x-ray study of the bladder and lower urinary tract, performed while the patient is urinating. This investigative procedure provides a comprehensive visual understanding of the functionality and structure of the lower urinary tract, including the bladder and the urethra. It is primarily employed to identify abnormalities such as vesicoureteral reflux (backward flow of urine from the bladder to the kidneys), urethral stricture, or any blockages in the urinary tract.
During the MCUG, a contrast dye is introduced into the bladder via a catheter. As the bladder fills up and the patient urinates, sequential x-ray images are captured. These images provide valuable insights into the structure and function of the urinary tract, helping doctors diagnose the cause of recurrent urinary tract infections (UTIs), issues with urine flow, or any congenital anomalies in children.

Before you undergo an MCUG, it's important to follow some specific instructions to ensure the process runs smoothly. It is not necessary to fast before the test. However, the bladder must be emptied before the start of the test. You may be asked to use a mild laxative or enema the night before to ensure your bowel is clear and does not obstruct the view of the bladder.
It's also crucial to inform your doctor about any medications you are taking, as some may need to be paused for the test. If you have any known allergies, especially to iodine or any contrast dyes, let your doctor know beforehand to avoid any potential reactions.
MCUG might cause some discomfort, particularly when the catheter is inserted and during the filling of the bladder. However, it is generally well-tolerated, and any discomfort should resolve quickly after the test. Pain medication can be administered if needed.
The entire procedure typically lasts about 30-60 minutes. However, the duration can vary based on individual circumstances.
A catheter is inserted through the urethra into the bladder. Then, the contrast dye is introduced into the bladder through the catheter. X-rays are taken as the bladder fills and as the patient urinates. The catheter is then removed.
It's best to wear loose, comfortable clothing. However, you may need to change into a hospital gown for the procedure.
After the MCUG, you may feel a mild burning sensation during urination, and there might be a slight risk of urinary tract infection. Drinking plenty of fluids can help alleviate any discomfort and lower the risk of infection.
If any abnormalities are detected during the MCUG, your doctor will discuss the findings and recommend the appropriate next steps. This could include further testing, medication, or in some cases, surgery.
Risks associated with MCUG are rare but can include urinary tract infections, allergic reactions to the contrast dye, and mild discomfort during or after the procedure.
MCUG is often recommended for patients who have recurrent urinary tract infections, unexplained blood in the urine, or suspected abnormalities in the lower urinary tract. It is also frequently performed in children to diagnose congenital urinary tract abnormalities.
If you experience severe pain, fever, or other worrying symptoms after the MCUG, it's important to seek immediate medical attention.
In case of abnormal findings in the MCUG, you should consult with a urologist for further evaluation and treatment.
MCUG is a valuable diagnostic tool for investigating potential abnormalities in the lower urinary tract. The procedure, though it may seem a bit daunting, is usually completed within an hour and can provide essential information to diagnose and manage conditions affecting urination. Always consult your doctor for more specific details related to your individual health situation and to clear any doubts you may have about the procedure.
