Ct ivp full form

The most common etiology of sudden onset of flank pain in adults is acute urolithiasis. Identification of a stone in the ureter or resultant partial or complete ureteral obstruction confirms the suspected diagnosis. Intravenous pyelography (IVP) has been the classic diagnostic test of choice. Noncontrast helical computed tomography (CT), which was introduced in 1994, has the advantages of avoiding contrast exposure, identifying radiolucent calculi, evaluating nearby structures, and requiring a shorter time for examination. Worster and associates reviewed the literature comparing the accuracy of noncontrast helical CT and IVP in identifying acute urolithiasis. Studies that compared these diagnostic tests from 1994 through 2000 were reviewed and included in the meta-analysis if they met prospective inclusion criteria, including requirements that both tests be conducted on the same day and that clinical follow-up occurred in at least 80 percent of the patients. The four studies (totaling 296 patients) that met all inclusion criteria showed noncontrast helical CT to be significantly more accurate in the diagnosis of acute urolithiasis. However, a systematic bias may have been present because noncontrast helical CT necessarily had to precede IVP to avoid residual contrast material. It is possible that some patients could have passed their stones after noncontrast helical CT and before IVP. editor's note: Noncontrast helical CT provides significantly enhanced ability to view the...

CT Intravenous Pyelogram (IVP/Urogram) Protocol CT Intravenous Pyelogram (CT IVP or CT Urogram) is an exam that uses an injection of contrast material into the veins followed by Computed Tomography imaging to evaluate kidneys, ureters, and bladder. The exam helps to diagnose urinary tract disorders such as kidney stones, urinary tract obstruction, or cancer. Often symptoms for this procedure are, but not limited to, hematuria (blood in the urine), flank (back) pain and abnormal lab work. Jump Ahead: • • • When contrast material is injected into a vein in the patient’s arm, it travels through the bloodstream and collects in the kidneys and urinary tract, turning these areas bright white on the x-ray images. A CT IVP allows the radiologist to view and assess the anatomy and function of the kidneys, ureters and the bladder and is a valuable tool for diagnosis and treatment. There are a variety of reasons why a patient might benefit from an IVP examination. The procedure helps the physician assess abnormalities within the patient’s urinary system by producing a clear, detailed image of the affected area. IVP also demonstrates the efficiency of the patient’s system in terms of handling fluid waste. Some of the common problems within a patient’s urinary tract include: • Enlarged prostate • Surgery performed on the urinary tract • Kidney stones • Scarring from a previous urinary tract infection (UTI) • Tumors in the ureters, kidney or bladder • Congenital abnormalities within the...

What Is an Intravenous Pyelogram? An Intravenous Pyelogram Purpose Your doctor may recommend this exam if you have This test lets your doctor see the size and shape of your bladder, kidneys, and ureters, and how well they’re working. They can spot blockages in your urinary tract caused by: • • • Tumors in the kidney, ureters, or bladder • Kidney cysts • Scarring, either from surgery or a • Congenital problems in the urinary tract, such as medullary sponge kidney. IVP images can give your doctor enough detailed information to treat a blockage with An intravenous pyelogram isn’t a good choice for everyone. Don’t get the procedure if: • You’re allergic to iodine or contrast dye. • You have • You’re • Infants and children rarely get IVPs. Intravenous Pyelogram Preparation Before you have the test, let your doctor know if you’re pregnant or have any medical conditions, if you have If you take any of these, you might need to stop before your procedure: • • • The doctor may ask you to take a mild laxative the night before the IVP and tell you not to eat or drink after midnight. You also may need a Intravenous Pyelogram Procedure You’ll probably change into a hospital gown. A lab technician will inject a liquid called a contrast material into your You’ll lie still on a table as the tech takes the X-rays. You may be asked to turn from side to side and hold different positions. The IVP shows the urinary tract in action as your kidney begins to empty into the ureters. These are the t...
