Tuberculosis (TB) remains a worldwide scourge and its incidence appears to be increasing due to various factors, such as the spread of human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS). The functions of the kidney are complex and include: (1) excretion of surplus water and the final metabolic products; (2) maintenance of the constant composition of body fluids; (3) preservation of the acid–base balance; and (4) endocrine function manifested as production and release of erythropoietin, renin and 1,25 dihydroxycholecalciferol.

An intravenous catheter is placed preferably into the cephalic vein, and the largest possible catheter (18–20 g) is recommended for ease of contrast medium administration and to avoid extravasation. 2), renal masses, and urothelial lesions (Fig. Ultravist ® Injection is available as a stable, ready-to-use aqueous solution of iopromide in vials or bottles in concentrations of 300 mg Iodine per mL, and 370 mg Iodine per mL. A properly performed study provides essential information regarding laterality, renal size, thickness, and architecture. Contrast-enhanced CT during the excretory phase can depict necrosis as clearly as does IV urography and thus allow accurate diagnosis of the condition 2 . Standard CT urography consists of unenhanced, nephrographic, and pyelographic phases. 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 []. Cystography is a fluoroscopic study that images the bladder. Solid renal tumors can grossly be categorized as completely solid, multifocal,.

Zanco J. The external urethral sphincter, located in the urogenital. The ureter begins its descent to the bladder by running along the medial aspect of the psoas muscle. 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. There is a strong male predilection. This is a review of the anatomy and physiology required to produce a normal nephrogram, as well as the basic principles affecting the interpretation of the nephrogram. But with IVP, the dye is injected into a vein instead. CT urography is the most accurate imaging technique for diagnosing dieases.

Previously, it described uses for the code in its descriptor including the words, “pyelostogram,” “nephrostogram” and “loopogram. Unless otherwise noted, protocols that include intravenous contrast enhancement use a 300 concentration, low- osmolality agent. B, T2-weighted static-fluid MR urograph confirms presence of filling defect (arrowhead) in renal pelvis. The absence of ionizing radiation makes it a suitable method for use in children. kidneys, pelvicalyceal systems, ureters and bladder. The purpose of this study was to determine whether a saline bolus during CT urography improves urinary collecting system opacification and whether the addition of enhanced CT digital radiography (CTDR) improves urinary collecting system visualization with or without a saline bolus.
