excretory (intravenous) urography is a common method for diagnosing diseases of the urogenital area.This procedure is based on the ability of the kidneys to deduce contrast agents (CA) from the blood.After intravenous administration of contrast material specialists carry out X-ray examination of the urinary tract and kidneys, which gives the opportunity to see the anatomical picture of these bodies, and to identify the pathology.

Performing excretory urography is strictly prohibited when:

  • hypersensitivity to iodinated contrast media;
  • autoimmune inflammatory diseases;
  • renal failure (both acute and chronic form);
  • acute glomerulonephritis;
  • thyrotoxicosis;
  • pheochromocytoma.

above study begins with the intravenous administration of contrast material, the amount of which depends on the patient's body weight.Five minutes after the introduction of the HF patient is sent to the X-ray room, where he made a serie

s of shots.The first X-ray is performed for 5-7 minutes (at this time is in the HF pyelocaliceal kidney system), the second - 10-15 minutes (at this time the contrast is moved to the ureters) and the third - 20-25 minutes (at this timeHF enters the cavity of the bladder).Sometimes the patient make two more X-rays - on 45 and 60 minutes.After intravenous urography urine may change its color (it usually becomes darker).

After the procedure urologist scrutinizes these photos.renal urography gives the opportunity to assess the contours of the position, size and shape of these organs.Also, this study to evaluate the shape and contours of the bladder and ureter.The main advantage of intravenous urography is considered that it is possible not only to determine the state of the urinary system, but also of the pelvic organs with the help of this procedure.During the study, doctors often detect cancers of internal organs and many other serious illnesses.

most frequent complications are excretory urography:

  • allergic reactions (sneezing, runny nose, swelling and redness of the skin);
  • Postinjection hematoma;
  • festering postinjection hematoma;
  • thrombophlebitis.

Possible complications

Most often complications when performing intravenous urography observed in patients who have contraindications to the procedure.For example, in glomerulonephritis or renal failure when administered HF marked renal operation, which usually leads to a deterioration of the general condition of pain in the lumbar region, a sharp increase in serum creatinine and urea, as well as a decrease in protein concentration in urine.

When appointed?

main indications for renal urography are:

  • blood in the urine (haematuria);
  • pain syndrome, which is associated with diseases of the urinary tract and kidneys;
  • recurrent infectious diseases of the urinary tract;
  • injury lumbar region;
  • suspected urolithiasis;
  • suspected obstruction (lumen closure) of the ureter;
  • diagnosis of congenital anomalies;
  • detection of complications after surgery.

How to prepare?

excretory urography no particular preparation of the patient is not required.This study from the beginning to the end is carried out at a medical facility.The only thing that the doctors may require patients who are afraid of injections and intravenous drips, it is mental attitude.
