BNO-IVP (Blass Nier Oversich – Intra Venous Pyelogram) is one of the x-ray test which provide you more detailed information about structure and function on both kidneys, ureters and urinary bladder.

What is the preparation of BNO-IVP?

1. You must get the prescription first from your requested Doctor to buy English Salt to clean-up your colon from gas and feces.

3. Anesthesiologist will inject the contrast media via hand vein (wrist region). The dosage is around 40 ml.

4. X-ray Technician (Radiographer/Operator) will make multiple radiography to trace contrast media flow from kidneys up to urinary bladder. I usually make in time period of 7 Minutes, 15′, 25′ and 45′ and then to be continued with Post-void after patient’s bladder is full of contrast media. If the drug we injected make a delay because of urinary tract abnormality we will wait the time until 2 hours or more.

The contrast media passes through the cyrculatory system and arrives at the kidneys then via ureters up to urinary bladder.
