Combined ultrasound — Radiographic detection of ureteral obstruction in renal transplants

Abstract
A case of renal transplantation is presented in which ultrasound was used to detect and control the puncture and aspiration of a renal abscess and a lymphocele. Subsequently, the combined sonographic-radiographic technique was used to diagnose and demonstrate the site of obstruction of the ureter. Ultrasound, in combination with fine-needle puncture when necessary, has many advantages in the management of renal transplantation.
