With the widespread implementation of CT urography, it is critical for radiologists to understand normal ureteral anatomy and the. The left side is as well affected twice as often as the right side. Oliguria with a urine output 100 to 400 mL per 24 hr is an expected finding for a client who has AKI. We would like to show you a description here but the site won’t allow us. Some authors defined loopogram as water-soluble contrast stomal enema that accesses. Fistulography is the most direct means of visualizing a fistula and should be considered when feasible (eg, cutaneous fistulas). Conventional radiography has only a moderate (60%) sensitivity for detecting renal and urinary tract calculi but in most circumstances remains the first-line imaging examination []. Locate the code selections which all represent abdominal x-rays. jleyende@wfubmc. An IVP is an imaging test used to look at the kidneys and ureters. Intravenous urography. This is evident on delayed images as the normal kidney shows contrast within the collecting system and ureters while the abnormal kidney does not. Pediatric MR urography can. The method reveals the stenosis of the pelvic-ureteral system, pelvic tumors, X-ray negative ureteral concretions. A CT urogram uses X-rays to generate multiple images of a slice of the area in your body being studied, including bones, soft. Urography is also often performed using computed tomography (CT) or magnetic resonance imaging (MRI). The ureters are the narrow tubes that carry urine from the kidneys to the bladder. The first approach combines axial CT with timed excretory urography (EU) performed by using conventional. help to evaluate functional and anatomical abnormalities of the. Specifically, to address the efforts urologist should be making to reduce the use of ionizing radiation and to examine alternatives to computerized tomography (CT) scan in diagnosing and managing patients with stones.

It is similar to a voiding cystourethrogram (VCUG), and the difference between the studies is primarily one of emphasis; a cystogram focuses on the bladder and a VCUG focuses on the posterior urethra. Dugdale, MD, Medical Director, Brenda Conaway, Editorial Director, and the A. If, on the one hand, this highlights the role of the radiologist in deciding the most suitable technique to perform according to the patient’s needs, on the other hand, a certain confusion may arise due to the different. The volume and rate of injection will depend primarily on the type of equipment and technique used. Recognizing the different nephrographic patterns on CT urography can be invaluable in understanding the morphologic and physiologic condition of the kidney and ultimately. The renal medulla and papillae are vulnerable to ischemic necrosis because of the peculiar arrangement of their blood supply and the hypertonic environment. Both of these terms are somewhat misleading, as this configuration is considered a developmental anomaly of the inferior vena cava (IVC). There is a recognized predilection towards the left side (~67% of cases). Consensus was strictly defined using a priori criteria. This article reviews the principles, indications, and pitfalls of intravenous urography, and provides examples of normal and abnormal findings. 2008 Jan;18 (1):4-17.

This test helps healthcare providers identify blockages in the urinary tract and may be used to identify the cause of hematuria. The procedure involves introducing contrast into the urinary system in a retrograde fashion with simultaneous imaging using dynamic fluoroscopy. The Current Procedural Terminology (CPT ®) code 74400 as maintained by American Medical Association, is a medical procedural code under the range - Diagnostic Radiology (Diagnostic Imaging) Procedures of the Urinary Tract. Imaging the urinary tract: Correct use of radiography and ultrasonography (Proceedings) Survey radiography is commonly used to image the urinary tract and provides information on size, shape, opacity, location and, margination of urinary organs. CT urograms use imaging and contrast dye to allow doctors to diagnose problems such as kidney and bladder stones, certain cancers, and structural irregularities. 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. The ureter begins its descent to the bladder by running along the medial aspect of the psoas muscle. Materials and methods: Fifty-nine examinations were performed in 53 pediatric patients and the degree of obstruction assessed using the renal transit time.
