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.
In the developed world, however, it has increasingly been replaced by contrast computed tomography of the urinary tract (CT urography), which gives greater detail of anatomy and function. History. The technique of IVP was originally developed by Leonard Rowntree of the Mayo Clinic in the 1920s.
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 ...
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.
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]
Laboratory investigations. Urinalysis is typically performed when LUTS are present and BPH is suspected to evaluate for signs of a urinary tract infection, glucose in the urine (suggestive of diabetes), or protein in the urine (suggestive of kidney disease). [2]
H&E stain. Transurethral resection of the prostate (commonly known as a TURP, plural TURPs, and rarely as a transurethral prostatic resection, TUPR) is a urological operation. It is used to treat benign prostatic hyperplasia (BPH). As the name indicates, it is performed by visualising the prostate through the urethra and removing tissue by ...
Three-dimensional reconstructed CT scan image of a ureteral stent in the left kidney (indicated by yellow arrow). There is a kidney stone in the pyelum of the lower pole of the kidney (higher red arrow) and one in the ureter beside the stent (lower red arrow).
A urethrotomy is an operation which involves incision of the urethra, especially for relief of a stricture. It is most often performed in the outpatient setting, with the patient (usually) being discharged from the hospital or surgery center within six hours from the procedure's inception. [citation needed] Urethrotomy (also referred to as DVIU ...
