title: [Native and contrast radiographic examination of the urinary tract].
abstract: BACKGROUND
  Plain x-rays and contrast urography are important for diagnosing urinary tract diseases. The first plain film of the urinary tract was made in 1896, and the first tests using contrasts started in 1904. Excretory urography has been used since 1930.
  Plain films of the urinary tract are used in the kidney area, the area of the ureter and urinary bladder. They also show structures (lumbar and sacral spine and pelvis), muscles (m. iliopsoas) as well as calculi.
  X-ray visualization of the urinary tract with contrast substances is intravenous urography. It is used for diagnosing diseases of the upper urinary system with symptoms such as: pain, colic, hydronephrosis, as well as acute cortical infections, urinary bladder tumors, etc.
  Retrograde urography is a procedure recommended when either the pyelocalyx system or the ureter are not seen unilaterally or bilaterally.
  Cystography is used to visualize the bladder. It is recommended in case of intravesical obstruction. Urethrocystography is a technique for investigation of the anterior and prostatic urethra as well as the neck of the urinary bladder.
