title: Small urine leak after renal transplantation: detection by delayed 99mTc-DTPA renography--a case report.
abstract: This case report involves a 45-y-old woman after cadaveric renal transplantation. The initial renal scan on the first postsurgical day showed normal findings. Subsequently, on the sixth postsurgical day, the patient had decreased urine output; 99mTc-diethylenetriaminepentaacetic acid renal scanning was performed again and did not show definite scintigraphic evidence of a urine leak. The patient's condition was not improving; renal scanning was repeated on day 20 and demonstrated a large photopenic region surrounding the superior, medial, and inferior aspects of the kidney. Delayed imaging was performed 2.5 h after injection of radiotracer, and activity was observed in the previously cold region.
