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.
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.
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
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 ...
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 ...
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.
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]
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 ...
Urology (from Greek οὖρον ouron "urine" and -λογία-logia "study of"), also known as genitourinary surgery, is the branch of medicine that focuses on surgical and medical diseases of the urinary system and the reproductive organs.
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.
