An antegrade urethrogram is a procedure allowing the urethra to be X-rayed when dye passes from the bladder through the urethra.

The bladder is first filled with X-ray dye. This can be done in two ways 1) a nurse will insert a urinary catheter into the bladder through the urethra or 2) the patient may already have a surgically inserted suprapubic catheter.

Urethrograms are performed by a Radiologist with a Radiographer and occasionally a nurse present. The study will be reported by a radiologist and the results sent to your doctor.

This procedure is available at the following Dr Jones & Partners locations:

Procedure

You will be provided an examination gown to wear and asked to remove your clothing in a cubicle that has an ensuite bathroom.

You will be asked to lie on your back on an X-ray table. The Radiologist will begin by gently cleaning the genital (or suprapubic) area with a specific antiseptic wash. A sterile drape is used to cover your groin and surrounding area.

Urethral Catheter Method

A small amount of anaesthetic gel is applied to the urethral opening to minimise discomfort. A urinary catheter is then inserted in the urethra until it reaches the bladder. A small balloon is inflated to hold it in place. The bladder is filled with X-ray dye to a point until you feel full. Once there is sufficient dye in the bladder the urethral catheter is removed. The X-ray table will be raised to a standing position by the radiographer. You will be handed a urine bottle that will catch the urine and dye while you to urinate (void) and the X-rays are taken. The radiologist will get the X-ray machine ready before instructing you to urinate into the bottle. Live X-rays are taken as the dye passes out the bladder through the urethra. It is common to have some difficulty voiding on command. Our experienced staff will support you patiently as needed.

Suprapubic Catheter Dye

The catheter bag is removed and an X-ray filled syringe is attached. The bladder is filled with X-ray dye to a point until you feel full. Once there is sufficient dye in the bladder the syringe is removed. The X-ray table will be raised by the Radiographer until you are in a standing position. You will be handed a urine bottle that will catch the urine and dye while you to urinate (void) and the X-rays are taken. The Radiologist will get the X-ray machine ready before instructing you to urinate into the bottle. Live X-rays are taken as the dye passes out the bladder through the urethra. It is common to have some difficulty voiding on command. Our experienced staff will support you patiently as needed.
