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. 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.
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. Retrograde pyelogram – Any pyelogram in which contrast medium is introduced from the lower urinary tract and flows ...
In urology, voiding cystourethrography (VCUG) is a frequently performed technique for visualizing a person's urethra and urinary bladder while the person urinates (voids). It is used in the diagnosis of vesicoureteral reflux (kidney reflux), among other disorders.
Near all stones are detectable on CT scans with the exception of those composed of certain drug residues in the urine, such as from indinavir. Where a CT scan is unavailable, an intravenous pyelogram may be performed to help confirm the diagnosis of urolithiasis.
Cystoscopy is endoscopy of the urinary bladder via the urethra. It is carried out with a cystoscope . The urethra is the tube that carries urine from the bladder to the outside of the body. The cystoscope has lenses like a telescope or microscope. These lenses let the physician focus on the inner surfaces of the urinary tract.
CT cystography. 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. See also
Retrograde urethrogram. Urethrogram showing an urethra stricture in a man. A retrograde urethrography [1] is a routine radiologic procedure (most typically in males) used to image the integrity of the urethra . Hence a retrograde urethrogram is essential for diagnosis of urethral injury, or urethral stricture. [2] [3]
Oncology Urology. Symptoms. Blood in the urine. Ureteral cancer is cancer of the ureters, muscular tubes that propel urine from the kidneys to the urinary bladder. It is also known as ureter cancer, [1] renal pelvic cancer, [1] and rarely ureteric cancer or uretal cancer. Cancer in this location is rare.
CT scan showing a ureterocele associated with a duplicated collection system of the left kidney. The signs and symptoms of ureterocele in the latter two forms can easily be confused with other medical conditions. Symptoms can include: [citation needed] Frequent urinary tract infections; Pyelonephritis; Obstructive voiding symptoms; Urinary ...
CT urography (CTU) is commonly used in the evaluation of hematuria, and specifically tailored to image the renal collecting system, ureters and bladder in addition to the renal parenchyma. Initial imaging includes a noncontrast phase to detect renal calculi as a source of hematuria.
