Indications Intravenous urography is suitable for:

1. Urinary calculi, tuberculosis, tumor, hydronephrosis and ureterocele.

2. Congenital malformation of urinary system and nephroptosis.

3. Urinary system trauma.

4. Make clear the relationship between abdominal mass and urinary system.

5. The cause of hematuria and pyuria is unknown.

6. Those who are unable to perform retrograde urography.

5 contraindications 1. Iodine contrast agent allergy.

2. Serious systemic diseases such as severe heart, liver and renal insufficiency.

6 ready 1. Patient preparation

(1) X-ray radiopaque drugs are prohibited 2 ~ 3 days before radiography.

(2) Eat less residue diet 65438+ 0 days before filming.

(3) Clean intestines and empty urine before radiography.

(4) Fasting and water deprivation 6 hours before radiography.

(5) Before iodine injection, the necessary treatment should be carried out according to the provisions of the Pharmacopoeia.

2. Comparative preparation? The contrast agent is ionic or nonionic with the corresponding iodine content of 76%, and the dose is 20 ~ 40 ml.

3. Preparation before photography

(1) Carefully check the application form for X-ray photography examination, understand the condition, and make clear the examination purpose and photography position. The application form with unclear examination purpose and photography position should be approved and confirmed by the clinician.

(2) Select films and cassettes with appropriate sizes according to the inspection site.

(3)X-ray photo marks (including patient film number, date, comparison photo serial number, marks around * * *, etc.). ) should be complete and correct.

(4) Start the machine for preheating, and draw up and adjust the photographic conditions.

(5) Remove items that may cause artifacts at the patient's examination site.

7 method 1. Photography * * *

(1) The patient lies on his back on the photographic bed, with his lower limbs straight, the median sagittal plane perpendicular to the tabletop and coincident with the center line of the long axis of the cassette, and his arms at his sides.

(2) At sacroiliac joint level, the lower ureter was compressed by pyelography compressor, inflatable balloon or pressurized abdominal band, and the pressure was generally 65438±04.7 kpa.

(3) The upper edge of Shuangshen tablet includes the 1 1 rib, and the lower edge includes the third lumbar vertebra.

(4) The center line of bilateral renal arteriography is vertically aligned with the midpoint of the connecting line between the sternal xiphoid process and the umbilicus, and shoots at the center of the film.

(5) The upper edge of total urography includes diaphragm and the lower edge includes pubic symphysis.

(6) Total urinary system photography, in which the center line is vertically incident on the film through the midpoint of the connecting line between xiphoid process and pubic symphysis.

(7) Use a wire filter.

(8) The photographic distance is 100cm.

(9) Hold your breath in a calm breathing state.

2. Photographic procedures

(1) Take a plain film of the abdomen before taking the film. If calcification is found in the renal area, take a lateral abdominal plain film.

(2) The kidneys were imaged at 7 minutes and 65438 05 minutes after injection of contrast agent, respectively, until the kidneys developed well.

(3) relieve abdominal compression and immediately take the whole urinary system for radiography.

(4) The photographer should fill in the relevant items and technical parameters of the inspection application form and sign it.

8 precautions 1. When the renal pelvis and calyx are still poorly developed after 30 minutes of injection of contrast agent, the photography time can be delayed.

2. Suspected nephroptosis, immediately after the abdominal compression is released, take the front and back radiographs of the standing abdomen.

3. Suspected bladder occupying lesions, after decompression, cystography should be done before urination.

4. Ureteral pressurization pressure is adjusted according to the patient's tolerance. During compression, if the patient has vagus nerve reaction and lower limb circulation disorder, he should immediately decompress or decompress.

5. When iodine allergy symptoms appear during radiography, the examination should be terminated immediately and symptomatic treatment should be carried out.
