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 ...
Attempts are made prior to surgery, through medical tests such as bone scans, computed tomography (CT), and magnetic resonance imaging (MRI), to identify cancer outside of the prostate. Radical retropubic prostatectomy may also be used if prostate cancer has failed to respond to radiation therapy , but the risk of urinary incontinence is ...
Transitional cell carcinoma, also called urothelial carcinoma, is a type of cancer that typically occurs in the urinary system. It is the most common type of bladder cancer and cancer of the ureter, urethra, and urachus. Symptoms of urothelial carcinoma in the bladder include hematuria (blood in the urine). Diagnosis includes urine analysis and ...
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.
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.
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.
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 ...
Specialty. urology. [ edit on Wikidata] Ureteral stent. Ureteral stent (detail) A ureteral stent (pronounced you-REE-ter-ul), or ureteric stent, is a thin tube inserted into the ureter to prevent or treat obstruction of the urine flow from the kidney.
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
