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. [1]
CT cystography is performed by filling up the urinary bladder using diluted iodinated contrast to visualise any bladder injury if the subject has haematuria (blood in urine) post trauma. Since CT cystography can be done together with CT abdomen and pelvis , it has supplanted conventional cystography in such cases.
Abdominal imaging is associated with many potential uses for the different phases of contrast CT.The majority of abdominal and pelvic CT's can be performed using a single-phase, but the evaluation of some tumor types (hepatic/pancreatic/renal), the urinary collecting system, and trauma patients among others, may be best performed with multiple phases.
Pyelogram (or pyelography or urography) is a form of imaging of the renal pelvis and ureter. [1]Types include: Intravenous pyelogram – In which a contrast solution is introduced through a vein into the circulatory system.
Spot images are taken at 30 to 45 degrees to visualise the entire spongy urethra (penile urethra). [ 4 ] If there is no contraindication to full urinary catheterisation such as false passage or stricture, the urinary catheter should be inserted until the urinary bladder to perform voiding cystourethrography to visualise the prostatic urethra ...
Fluoroscopic spot images and videos are taken during the micturition phase to detect any reflux. The lower ureter is best seen on an anterior oblique position. In males, peeing should be done in oblique or lateral positions to visualise the whole of urethra. Finally, the whole abdomen is imaged to detect any undetected reflux in previous images.
An intravenous pyelogram, also called an intravenous urogram (IVU), is a radiological procedure used to visualize abnormalities of the urinary system, including the kidneys, ureters, and bladder. Unlike a kidneys, ureters, and bladder x-ray (KUB), which is a plain (that is, noncontrast) radiograph, an IVP uses contrast to highlight the urinary ...
Ultrasound involves a probe that is placed near a structure and uses the transmission of ultrasound waves through a structure to produce images, after computer processing. [1] Ultrasound of the urinary tract is performed by a probe placed on the abdominal wall, called a transducer. [1] This occurs while a person is lying down. [1]
