IVU / IVP, MCU, RGU, HSG, Fistulography and Sinusography

Advanced Radiology

IVU (Intravenous Urography)

In this procedure, a dye is injected intravenously and X-ray pictures of the kidneys, uterus and bladder are obtained. The dye is radio-opaque and seen well with X-rays. Overnight fasting and good preparation of the colon with laxatives are required.

MCU (Micturating Cystourethrography)

Dye is introduced into the urinary bladder and the patient is asked to micturate/urinate. X-ray pictures are obtained during the act of micturition to assess the function and structure of the urinary bladder and urethra.

RGU (Retrograde Urethrography)

Dye is injected through the urethra from the glans penis and X-ray pictures are taken. This helps in assessing the urethra and the bladder base.

Fistulogram and Sinusogram

In these studies, using a small catheter, iodinated dye is injected into the cutaneous sinus or fistula and X-rays are taken, which help in identifying the tract of the sinus or fistula.

Sialography

In this, the parotid duct is cannulated from the mouth and X-ray pictures of the parotid duct and gland are obtained.

Angiography and Venography

The arteries are catheterized usually through the femoral artery and after the injection of iodinated dye, X-rays are taken. If the same study is performed for the veins, we get venograms.

HSG (Hysterosalpingography)

The cervix is cannulated and iodinated dye is injected into the cervical and uterine lumen. The Fallopian tubes are then well seen. This procedure is used to study the patency of the passage as well as other structural abnormalities.

Frequently Asked Questions

What are these medical imaging tests ?

These are X-ray procedures that examine different parts of your body:

IVU/IVP (Intravenous Urography/Pyelogram): Checks your urinary system for issues like kidney stones or tumors.

MCU (Micturating Cystourethrogram): Examines your bladder and urethra while you urinate, helping diagnose problems like reflux or abnormalities.

RGU (Retrograde Urethrogram): Specifically looks at the male urethra to check for strictures or injuries.

HSG (Hysterosalpingogram): Investigates the uterus and fallopian tubes, often for infertility or uterine issues.

Fistulography: Visualizes abnormal connections between organs or the skin.

Sinusography: Diagnoses infections or structural problems in your sinuses.

Why would my doctor order one of these tests ?

Your doctor may recommend these tests to:

Check for kidney stones, tumors, or blockages in the urinary tract (IVU/IVP)

Diagnose urinary reflux or bladder problems (MCU)

Evaluate injuries or strictures in the male urethra (RGU)

Investigate infertility or uterine issues (HSG)

Examine abnormal organ connections or skin openings (Fistulography)

Diagnose sinus infections or structural problems (Sinusography)

How do I prepare for these tests?

Preparation varies, but:

You may need to fast for a few hours.

Tell the staff about any allergies, especially to contrast materials.

If you're female, inform them if you might be pregnant.

Follow any specific instructions from Dr. Vaya's Lab.

Are these tests painful ?

Most involve minimal discomfort. Some, like HSG or RGU, may cause brief discomfort when catheters or contrast material are inserted. Our staff will ensure your comfort.

How long do the tests take?

IVU/IVP: About 1 hour
MCU: 30-60 minutes
RGU: 15-30 minutes
HSG: 30 minutes
Fistulography and Sinusography: 30-60 minutes

Plan to spend more time at the lab for preparation and post-test care.

What are the risks ?

These tests are generally safe, but there's a rare chance of:

Allergic reaction to contrast material

Infection

Exposure to small amounts of radiation

Our staff will discuss specific risks with you beforehand.

When will I get my results ?

We strive to provide results within 24-48 hours. For urgent cases, we may have results sooner.
