A hysterosalpingogram (HSG) is a test used to investigate the uterine cavity and to check for opening of the fallopian tubes. A dye is put into the uterus and fallopian tubes before the images are taken.
An HSG is done to:
- Check for a blocked fallopian tube.
- Find problems in the uterus, such as an abnormal shape or structure.
- Look for an injury, polyps, fibroids, adhesions, or a foreign object in the uterus.
This test is performed by a gynecologist and an X-ray technologist will assist and take the images. At times there may be medical trainees present (medical students, residents, or X-ray technologists in training).
It is normal to experience spotting in the few days following the procedure. You may use a pad, but do not insert a tampon the day of the procedure.
A voiding cystourethrogram (SIS-toe-you-REE-throw-gram) or VCUG is a type of video X-ray of the bladder and kidneys at work.
The kidneys produce urine, the ureters bring the urine to the bladder, and the bladder stores urine until you need to go to the bathroom.
The test involves filling your child’s bladder through a catheter with a special liquid that is visible on X-ray. A Radiologist, a specialist X-ray doctor, will place an X-ray camera over your child which will take moving video like pictures of the urinary system. The images will be visible on a television monitor in the room.
The role of a parent/guardian during a VCUG
We welcome your help and support during this test. One parent is invited to join the child in the examination room. The test involves the use of radiation—women who are pregnant or think they may be pregnant will not be allowed in the examination room. In this case please bring another adult who can stay with your child in the room.
The X-ray technologist will show you where to stand during the examination. You will be asked to wear a lead apron and neck shield.
The parent’s most important role is to help your child remain calm and relaxed, particularly when the catheter is being inserted.
We encourage you to talk to your child during the procedure and holding his/her hand will not disrupt the test in any way.
VCUG for Boys
A boy will be asked to lie on the table. The nurse will wash the tip of his penis around the opening where the urine comes out, this may feel cold.
A tiny soft tube called a catheter will be placed into the opening of the penis (urethra). This may be a bit unpleasant and he made need comforting during this part of the procedure.
The doctor will then begin to move the X-ray machine around and take pictures as the X-ray liquid flows through the catheter into the bladder.
Once the bladder is full he will be asked to urinate into a special bottle, this will make the catheter fall out.
More X-rays will be taken as the bladder empties.
VCUG for Girls
A girl will be asked to lie on the table, often in the “frog” position—bending her knees and putting the bottoms of her feet together. The nurse will then clean the genital area with a special soap—this may feel cold.
The nurse will then slide a very tiny soft tube called a catheter into the urethra (the opening where urine leaves the body). This can be unpleasant and she may need comforting during this part of the exam.
The doctor will then begin to move the X-ray machine around and take pictures as the X-ray liquid flows through the catheter into the bladder.Once the bladder is full she will be asked to urinate on a pad, this will make the catheter fall out.
What to expect after the VCUG
After a VCUG your child may feel a little sore the next few times they have to urinate. Drinking lots of liquids may help relieve the soreness more quickly.
A report will be sent to your doctor in the next week.
