cystography

Bladder angiography is a method of inserting a catheter into the bladder and injecting 100-200 ml of 3% to 6% sodium iodide solution to develop the bladder. Mainly used for the diagnosis of bladder tumors, bladder diverticulum, external compression, such as prostatic hypertrophy and other diseases. The catheter is inserted into the anterior urethra, or the syringe is directly placed against the urethral opening, and 12.5% ​​sodium iodide or 15% to 25% diatrizoate is injected to show the lesion of the male urethra. At the end of the excretory urography, urinary urinary tract photography during urination can also be performed for excretion of urethral angiography. Basic Information Specialist classification: urinary examination classification: X-ray Applicable gender: whether men and women apply fasting: not fasting Tips: Drink plenty of water after the test, or use some antibiotics to prevent urinary tract infections. Normal value Cyst angiography shows that there is a curved impression on the bottom of the bladder, or that the shadow of the tumor protrudes upwards, and the edges are often smooth and tidy, and may also become slightly leafy. The posterior urethra is deformed by compression, which is characterized by elongation, stenosis and an increase in normal curvature. In addition, bladder changes caused by chronic obstruction, such as a conical bladder and irregular edges, can be seen. Clinical significance Cyst angiography shows that there is a curved impression on the bottom of the bladder, or that the shadow of the tumor protrudes upwards, and the edges are often smooth and tidy, and may also become slightly leafy. The posterior urethra is deformed by compression, which is characterized by elongation, stenosis and an increase in normal curvature. In addition, bladder changes caused by chronic obstruction, such as a conical bladder and irregular edges, can be seen. If radioactive images appear in the ureter or kidney area, it is evidence of reflux. If there is any clear increase in radioactivity in the ureter or kidney, it indicates that there is reflux in the bladder urine. Mainly used for the diagnosis of bladder tumors, bladder diverticulum, external compression, such as prostatic hypertrophy and other diseases. Precautions Before the test: Iodine allergy test. After the test: drink plenty of water, you can also use some antibiotics to prevent urinary tract infections. Generally strict aseptic operation is no problem. Contraindications: First, allergies to contrast agents. Second, urinary tract infections. Third, when there is major bleeding, wait until the blood is stopped.
