Intravenous urography is a radiological diagnostic method of recording the kidney and urinary tract (ureter, bladder and urethra). This method is performed by a peripheral vein injected iodine contrast agent, which is then excreted by the kidneys and urinary tract. In this way, we get an insight into the function of the kidney and urinary tract anatomy. Thus, intravenous urography allows us to reduce diagnostic or absence of renal function, and visualization of different pathological processes in the urinary tract (tumors, stones, congenital anomalies, chronic inflammatory changes, halt the flow of urine, enlargement of the prostate, etc.)..
Prepare patient for examination involves taking laksativnih resources and avoiding foods that doovode to the formation of gas in the intestines, for 2 to 3 days prior to the examination. A few hours before the examination the patient should not take water.
A simple glance is quite simple and is performed during the patient lying on the radiological table.Initially do so. native footage of the urinary tract and then gives a vein contrast agent. During the scan, which takes about 45 minutes and sometimes hours or more, depending on renal function, repeated doses of x-rays of the right urinary tract.
Indications for the use of this diagnostic method has narrowed in recent years due to the introduction into clinical practice of diagnostic ultrasound, computed tomography and magnetic resonance imaging. However, the diagnostic procedure is still very useful in the diagnosis of certain pathological conditions, especially diseases ureter and urinary systems. The disadvantages of this method are mainly related to exposure to ionizing radiation and receiving contrast agent that can cause severe allergic reactions or renal function (especially in patients who already have impaired renal function or in patients with diabetes). An indication for this examination always ask the urologist or nephrologist. Sensitization of the patient to the contrast agent is an absolute contraindication for the use of this diagnostic method.
