title: Fine-needle antegrade pyelography of transplanted kidneys.
abstract: Ureteral obstruction or perforation must be considered as a cause of poorly functioning renal transplants. Sonography and radionuclide scanning will demonstrate outflow obstruction and/or pararenal fluid collection, but do not usually provide sufficient information on the site of the lesion. In these cases we have successfully used fine-needle puncture of the renal pelvis under sonographic guidance, and antegrade pyelography. This technique shows excellent anatomical details of the renal pelvis and ureter.
