Fluid collections following renal transplantation are not rare and may be associated with serious complications. We studied the incidence, clinical features, pathology and treatment outcome of perirenal fluid collections after kidney transplantation. Between January 1977 and June 1985, 386 consecutive renal transplants were performed at our university. All(More)
Kidney transplantation is a successful treatment for end-stage renal disease. We studied demographic and psychosocial variables that relate to compliance behaviors following renal transplant. One hundred and five renal allograft recipients, with a minimum of 18 months follow-up, were studied. A biographical questionnaire, the Center for Epidemiologic(More)
Over a 7-year period the authors studied the vascular and ureteric anomalies of kidneys procured from brain dead, heart-beating cadavers for the purposes of transplantation. Four hundred donors had a bilateral nephroureterectomy performed using an en-bloc technique, followed by fine anatomical dissection in cold saline slush solution. Thus, 800 kidneys were(More)
Thirty of 110 HLA-mismatched renal allograft recipients were converted from CsA to Aza due to CsA nephrotoxicity or side effects, persistent posttransplant ATN, noncompliance, or patient desire to reduce the cost of maintenance immunosuppression. The majority of patients studied were cadaver transplant recipients. Renal function improved significantly in(More)
BACKGROUND We performed a prospective randomized trial to compare the efficacy and safety of tacrolimus (FK506) versus cyclosporine (CSA) in black primary cadaveric renal transplant (CRT) recipients. METHODS Between December 1994 and February 1997, 35 black primary CRT recipients were enrolled in this trial. All patients received 7 days of induction(More)
UNLABELLED We conducted a prospective, randomized study comparing transcatheter partial splenic embolization (PSE) with splenectomy (SX) in 53 renal transplant candidates. An additional 112 PSE procedures were performed for various indications in 101 patients. STUDY RESULTS A mean +/- SD of 65% +/- 16% of splenic mass was ablated in the PSE group. The(More)
Prolonged vascularized organ allograft survival and an improved quality of life are now possible for many transplant recipients. These advances are due largely to greater understanding of the immune response, the development of potent immunosuppressive agents (cyclosporin A), and improved surgical techniques. Thus more of these patients may require surgical(More)
Permanent donor-specific tolerance to allografts is the goal of transplantation research. Currently, morbid immunosuppressive therapy is used to mitigate rejection initiated in part by Ia-bearing interstitial graft dendritic or antigen-presenting cells (APCs) that are thought to migrate into the host after transplantation. We hypothesized that donor or(More)
Oxygen free radical generation has been implicated as a possible mediator of the reperfusion injury postulated to occur following revascularization of the cold preserved and transplanted kidney. The superoxide radical (O2-) scavenger, superoxide dismutase, from bovine or recombinant (rh-SOD) sources, may ameliorate oxygen-free-radical mediated reperfusion(More)
