Comprehensive Guide to Urinary System IVP/IVU Procedures and Function Assessment

This document outlines the IVP (Intravenous Pyelogram) or IVU (Intravenous Urogram) procedures for assessing kidney function. It details a timed examination with exposures taken at various intervals, including oblique views and specific positioning techniques. The guide elaborates on catheterization for retrograde urography, the visualization of ureters, and conditions diagnosed such as renal cell carcinoma and urinary tract obstructions. It also discusses cystography techniques for bladder evaluation, ensuring thorough examination protocols.

  2. IVP or IVU • This is a timed exam. The intent is to determine the function of the kidneys. • A series of exposures will be made from 1 to 20 minutes. • 30 degree obliques may be done at 5 – 10 minutes post injection. • Most early films, before 10 minutes, will be cone downs. • 15 minute film maybe prone

  3. IVP

  4. 10 minutes

  5. 10 minute LPO

  6. 15 minute prone

  7. Retrograde urography • Catheterization followed by direct contrast injection • Excellent visualization of the ureters • No kidney function

  8. Cystography • Small films • AP, bilateral obliques (40-60 degrees), lateral • For voiding exams rotate the patient 35-40 degrees
