title: Acute urinary retention secondary to a urethral calculus in a bladder-drained kidney pancreas transplant patient - a metallic clip nidus.
abstract: Urological expertise is usually required for the management of any urological complications of bladder-drained pancreatic allografts whether they are the result of simultaneous pancreas-kidney transplants, pancreas after kidney transplants, or pancreas transplants alone. This study presents a case of urinary retention secondary to prostatic urethra calculus impaction, the nidus of which was found to be metallic staples from the donor duodenal segment of a pancreatic allograft. Knowledge of the pre-transplant benchwork gave a high index of suspicion to the urological sequelae of this case and, in particular, the presence of calculi should suggest a metal clip nidus. We examine the methods of exocrine pancreatic drainage, donor duodenum preparation and case management.
