    15 minute X-ray of just the renal area. At this point, compression may or may not be applied (this is contraindicated in cases of obstruction). In pyelography, compression involves pressing on the lower abdominal area, which results in distension of the upper urinary tract. [8] If compression is applied: a 10 minutes post-injection X-ray of the ...

    Using a urinary catheter, radiocontrast is instilled in the bladder, and X-ray imaging is performed. Cystography can be used to evaluate bladder cancer, vesicoureteral reflux, bladder polyps, and hydronephrosis. It requires less radiation than pelvic CT, although it is less sensitive and specific than MRI or CT.
