Patients with a kidney stone and obstruction are usually required to stay in hospital for monitoring or further treatment. An Emergency IVP is carried out roughly as follows: plain KUB or abdominal X-ray; an injection of contrast media, typically 50 ml; delayed abdominal X-ray, taken at roughly 15 minutes post injection.
In children, abdominal x-ray is indicated in the acute setting: Suspected bowel obstruction or gastrointestinal perforation; Abdominal x-ray will demonstrate most cases of bowel obstruction, by showing dilated bowel loops. [1] Foreign body in the alimentary tract; can be identified if it is radiodense. [1] Suspected abdominal mass [1]
In radiology and urology, a cystography (also known as cystogram) is a procedure used to visualise the urinary bladder. 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.
A urologist and surgeon, he treats all kinds of conditions, from complex kidney stones to incontinence to urologic cancers. But no matter why someone ends up in his exam room, he asks the same ...
Under fluoroscopy (real time x-rays) the radiologist watches the contrast enter the bladder and looks at the anatomy of the patient. If the contrast moves into the ureters and back into the kidneys , the radiologist makes the diagnosis of vesicoureteral reflux , and gives the degree of severity a score.
Determination of how much urine is in the bladder, for example to assess for urinary retention. To look for evidence and the cause of chronic kidney disease, for example shrunken kidneys. [1] To assist with an interventional procedure, such as the taking of a biopsy, or draining of an abscess or cyst. [1] To monitor a kidney transplant. [1]
A computed tomography urography (CT urography or CT urogram) is a computed tomography scan that examines the urinary tract after contrast dye is injected into a vein. [1]In a CT urogram, the contrast agent is through a cannula into a vein, allowed to be cleared by the kidneys and excreted through the urinary tract as part of the urine.
A voiding cystogram is a functional study where contrast "dye" is injected through a catheter into the bladder. Under x-ray the radiologist asks the patient to void (usually young children) and will watch the contrast exiting the body on the x-ray monitor. This examines the child's bladder and lower urinary tract.
