CT renal exam. A ct without and then with IV contrast may give an accurate evaluation of the kidneys and ureters. Occasionally, small tumors, or stones may only be seen by retrograde pyelography.
IV pyelogram. However, it entails IV infusion of contrast which may have side effects on kidneys. The retrograde study should not hurt the kidneys.
Retrograde. Pyelogram is a procedure typically performed by a urologist. He/she injects contrast into the ureter in order to visualize the ureter and kidney. The flow of contrast (up from the bladder to the kidney) is opposite the usual flow of urine, hence the retrograde name.
Xray with contrast. Rarely done nowadays. Crags taken after injecting dye into urinary tract.
See inside ureters. "the retrograde pyelogram uses a dye to determine whether a kidney stone or something else is blocking your urinary tract" see: http://www. Webmd. Com/kidney-stones/retrograde-pyelogram-for-kidney-stones.
Hydrate well. Hydrate well, keep your stomach empty overnight. Last thing you want is to get nauseous.
Nothing. There's not really anything you should need to do to prepare ahead of time for such a procedure. But, if so, your urologist should inform you of any preprocedure preparation.
Exam by doctor. In a retrograde pyelogram a urologist will place a small tube through your bladder up the ureters and inject contrast to visualize the size and shape of the ureters. You will be sedated during the procedure.
Pyelogram. Is an invasive procedure in which you place a cystoscope through the urethra, then pass a small catheter through the scope into the opening of the ureter into the bladder and inject contrast material into the kidney to study the anatomy of the drainage system of the kidney and take x.-rays usually under fluoroscopic control.
Venous vs urethra. Intravenous pyelogram demonstrates kidneys, ureters and bladder by intravenous injection of contrast material while with retrograde study scope is introduced via urethra with injection of contrast material directly into ureters and kidneys.
Study of kidneys and. Normally the kidneys and ureters are studied by IVP exam where contrast is injected into veins and excreted by the kidneys. Sometimes, visualizations by this method is inadequate. Thru a cystoscope or ureteroscope, a small catheter is inserted into the ureter and contrast injected into the ureter visualizing it and the renal collecting system, the renal pelvis, thus a retrograde pyelogram.
