BACKGROUND Transplant glomerulopathy (TG) is a renal allograft disease defined by glomerular basement membrane duplication with peritubular capillary basement membrane multilayering (PTCML), and associated with anti-human leukocyte antigen antibodies and C4d. Outcome in TG is poor but variable, and prognostic factors, particularly those affecting long-term(More)
Older living kidney donors are regularly accepted. Better knowledge of recipient outcomes is needed to inform this practice. This retrospective cohort study observed kidney allograft recipients from Ontario, Canada between January 2000 and March 2008. Donors to these recipients were older living (≥ 60 years), younger living, or standard criteria deceased(More)
BACKGROUND With rates of obesity among patients with chronic kidney disease (CKD) mirroring that of the general population, there is growing interest in offering bariatric surgery to these patients. We sought to determine the safety of bariatric surgery in this patient population. METHODS Patients who underwent selected laparoscopic bariatric procedures(More)
BACKGROUND The kidney is the most common transplanted organ, accounting for almost all living donor transplantations and most deceased donor organ transplantations. The organ shortage has caused policymakers in many nations to debate the merits of adopting presumed consent legislation as a way to increase donor organ donation from deceased donors. (More)
BACKGROUND AND OBJECTIVES Guidelines promote early fistula creation to avoid central venous catheter use. This practice may lead to fistula creations in patients who never receive dialysis. The objective of this study was to estimate the risk of fistula nonuse with long-term follow-up. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Administrative health(More)
Individuals with moderate-to-severe reduced renal function have greater risk of gastrointestinal bleeding than those with normal renal function. We conducted a retrospective matched cohort study to assess whether living kidney donors share a similar risk. We reviewed pre-donation charts for living kidney donations from 1992 to 2009 in Ontario, Canada, and(More)
IMPORTANCE Solid-organ transplant recipients (SOTRs) are at greater risk of developing some cancers than the general population; however, because they are also at increased risk of mortality from noncancer causes, the effect of transplantation on cancer mortality is unclear. OBJECTIVE To describe cancer mortality in SOTRs and to assess whether SOTRs are(More)
Warm ischemia time is a potentially modifiable insult to transplanted kidneys, but little is known about its effect on long-term outcomes. Here we conducted a study of United States kidney transplant recipients (years 2000-2013) to determine the association between warm ischemia time (the time from organ removal from cold storage to reperfusion with warm(More)
When evaluating a living kidney donor and recipient with a father-child relationship, it may be discovered that the two are not biologically related. We analyzed data from the United Network for Organ Sharing and the Canadian Organ Replacement Registry to determine how frequently this occurs. We surveyed 102 potential donors, recipients, and transplant(More)
