Laparoscopic management of extensive ureteral fibroepithelial polyps.

Fibroepthelial polyps are uniformly benign tumors of the collecting system which may cause obstruction of an affected renal unit. We present a unique case of a 34-year-old male with a solitary functioning kidney who presented with flank pain and renal insufficiency. Radiographic and ureteroscopic evaluation revealed ureteral obstruction due to extensive polyps.

Altruistic donation through the Alliance for Paired Donation.

Kidney paired donation is an evolving strategy for overcoming the incompatibility barrier inherent in living donor kidney transplantation. As evidence of the growing interest in this new approach, more than 800 paired donation transplants have been performed in the United States as of February 2010, greater than half of which were performed in 2008 and 2009. Recent advances in this field have incorporated non-directed or altruistic donors to initiate chains of transplants that are either performed simultaneously, or by utilizing "bridge donors" who continue a nonsimultaneous chain at a later date.
