| Why would you or your child need the Micturating Cystogram (MCU)? |
This is for the assessment of the bladder, and the upper tracts (kidneys and ureters). This is a common investigation in the child with recurrent urinary infections. This may also be used in the baby with ambiguous genitalia (uncommon condition). |
| What are the special preparations and precautions? |
There are no special precautions, unless the patient is a child and is too young to cooperate and or the patient requires antibiotic cover for the examination. The necessary sedation and antibiotic cover will be arranged by your doctor or the paediatrician for the child who is too young to cooperate. |
What is done? |
If this is done after an operation, there is usually a urinary catheter (fine tube passed through your urethra to help you pass urine) already. Otherwise, your doctor/paediatrician will insert one into the bladder through the urethra. The Radiologist may be the one catheterising the child/patient. After this, iodine-containing contrast is instilled into the bladder until it is “full”. The Radiologist will be able to see this, as “x-rays” will be used to visualise the process of contrast instillation. The child/patient will be encouraged to pass urine and films (x-rays) of the process of micturating (passing urine) are taken. Sometimes, there is a need to look for the contrast in the kidneys if it refluxes up (flows back) the ureters. The catheter is removed during the process of passing urine so that the urethra can be outlined in contrast.
|
Are there any side effects or complications? |
Some of the following may occur but are usually transient and will settle on it’s own. Please continue to take any antibiotics prescribed by your doctor/paediatrician as this will help to prevent any infection. Irritation of the bladder from the contrast media. (usually transient) Infection and inflammation (this can be treated or prevented with judicious use of antibiotics) Other reactions to the contrast media. (Please see contrast media FAQ) Local trauma at the urethra and reluctance or difficult passing urine. Minor bleeding from trauma.
|
What do I do after the MCU? |
Encourage the child to drink plenty of fluids. If the child is afraid to pass urine because of some pain at the site of the urethra, allow the child to sit in a warm water bath and pass urine while submerged in the warm water. There may be some blood in the urine but this should clear. Should the child/patient be unable to pass urine or have severe pain, please consult your doctor as soon as possible.
Your doctor may have further instructions depending on your condition. This may include antibiotics for a few more days. |
