Fine Needle Antegrade Pyelography in the Renal Transplant

Antegrade pyelography by fine needle puncture provides superior anatomic detail of the transplant ureter. It is the most accurate and informative examination for ureteral stricture and perforation, providing information not usually obtainable by excretory urography, radionuclide scan, ultrasound or retrograde pyelography. We herein describe our technique of fine needles antegrade pyelography and its application in 11 patients. The method is remarkably safe, with no clinical significant complications in this series or in a literature survey of 734 other fine needle kidney punctures.
