A contrast material is injected into the body through the veins to examine the urinary tract organs. Oblivion:Lord Rugdumph gro-Shurgak. Background Children are frequently referred to the pediatric radiology department due to complaints related to the urinary tract. MR urography correctly showed normal insertion in 7/19 children. We have restrospectively analyzed computed tomography urography image series performed in the Department of Pediatric Radiology, in children with suspected congenital anomalies of the kidney and the urinary tract. 1055/s-2003-37229. Sometimes x-rays can help detect certain types of kidney stones Stones in the Urinary Tract Stones (calculi) are hard masses that form in the urinary tract and may cause pain, bleeding, or an infection or block of the flow of urine. MR-urography (MRU) and CT-urography (CTU) provide refined imaging of the upper urinary tract not achievable with conventional intravenous urography (IVU). McClennan said "patient selection for urographic studies should be. We would like to show you a description here but the site won’t allow us. This page contains 10 words. IVU is now infrequently used in the assessment of a pediatric patient. During the test, the radiologist injects a contrast dye into one of your veins. INTRODUCTION IVU is the radiographic examination of urinary tract including renal parenchyma, calyces and pelvis after intravenous injection of contrast media. Therefore, in most centers, a three-phase CT urographic protocol, consisting of unenhanced, nephrographic, and excretory phases, is performed [ 1, 3, 7 ]. 1007/s00330-007-0792-x. One of these children had an ectopic ureter on cystoscopy and surgery. , Following administration of oral contrast medium, gallbladder x-ray indicates satisfactory concentration, the outline is. Magnetic resonance urography (MRU) is increasingly being used for comprehensive anatomic and functional evaluation of the urinary tract in children. With expansions in use of cross-sectional imaging, the computed tomographic (CT) nephrogram (ie, contrast material enhancement within the renal parenchyma) has assumed a greater role in the evaluation of urinary tract disorders. CTU Technique. Urography is also often performed using computed tomography (CT) or magnetic resonance imaging (MRI). Pediatric MR urography can be used to thoroughly evaluate renal and urinary tract abnormalities that are difficult to identify or fully characterize with other imaging techniques, and it has the potential to allow earlier diagnosis while decreasing the number of imaging studies performed. Several techniques have been developed to measure the DRF with MRI by using the area under the time-intensity curve obtained from either a single slice, or a few slices, with a separate volume measurement [10, 27, 44,45,46]. Introduction Urethrography is most commonly performed via the retrograde injection of radiopaque contrast into the urethra to elucidate urethral. Unenhanced images are obtained from the kidneys to the bladder and allow optimal detection of renal calculi, a. urography, X-ray examination of any part of the urinary tract after introduction of a radiopaque substance (often an organic iodine derivative) that casts an X-ray shadow. There are two types of MR urography: static fluid-sensitive urography that is heavily T2-weighted to image the fluid-filled urinary system and excretory MR. com • 2021-07-18 • 资源分享. b. It can be used to assess congenital anomalies of the kidney and urinary tract, which often present as urinary tract dilation.

IntroductionMegaureter, described as ureter dilatation more than 7 mm in diameter, commonly associated with other anomalies, is still a diagnostic and therapeutic challenge. E. BUN 30 mg/dL is correct. It has little diagnostic role to detect the cause of obstruction. Oliguria with a urine output 100 to 400 mL per 24 hr is an expected finding for a client who has AKI. Most three-phase MDCTU protocols comprise an initial non-contrast phase to detect urinary tract calculi and a second phase, i. Delayed diagnosis can lead to. Computed tomography urography (CTU) is now considered the imaging modality of choice for diagnosis and staging of UTUC, guiding disease management. Intravenous urography is a radiographic technique that uses iodinated contrast material to visualize the urinary tract. abdominal pain or mass, such as swelling in a. It gives both anatomical and functional information, albeit with a relatively higher dose of radiation. The language of radiology is rich with descriptions of imaging findings, often metaphorical, which have found common usage in the day-to-day practice of genitourinary radiology. In the remaining 3/19 children distal ureter could not be seen, hence insertion was indeterminate on MR urography. This study intends to evaluate the utility of this imaging combination in terms of the yield of abnormal findings on the follow up RPG. The term "urography" refers to evaluation of the entire urinary tract, ie. 100%. A retrograde urethrography [1] is a routine radiologic procedure (most typically in males) used to image the integrity of the urethra . Multi-detector row CT urography depicted many clinically diagnosed urinary tract abnormalities, including 15 of 16 uroepithelial malignancies, five congenital anomalies, five urinary tract calculi, and 18 calyceal and/or papillary, 30 renal pelvic and/or ureteral, and 25 bladder abnormalities.
