Kidney transplantation at the University of Maryland.

1. The number of kidney transplants performed at the University of Maryland increased yearly from 51 in 1991 to 285 in 1998. Over the past 3 years, the increase in the number of kidney transplants can be ascribed almost exclusively to a marked increase in living donor transplants, from 49 cases in 1995 to 130 cases in 1998; a 160% increase. The increase in our frequency of living-donor kidney transplantation can be attributed to a formal family education program and the availability of the laparoscopic technique for kidney removal. 2. In addition to the availability of the laparoscopic technique, a number of special programs has allowed an increased number of living donor kidney transplants. This includes a special protocol for transplantation of Epstein-Barr virus negative recipients, a protocol for transplantation of patients who have a positive crossmatch with a living donor, as well as, the simultaneous living donor kidney/cadaver pancreas "SPK(LRD/PTA)" program. 3. The one-year graft and patient survival for the entire program was 87.0% and 94.5%, respectively. However, the more recent graft survival rates have markedly increased; Since August 1995, the one-year graft and patient survival was 89.8% and 95.8%, respectively. 4. Improvement in immunosuppression has lead to dramatic improvement in the success rates in living-donor kidney transplants. Despite the omission of antibody-based induction therapy, the one-year graft survival rate using a mycophenolate mofetil/tacrolimus-based immunosuppression protocol was 96.4%. The one-year rejection rate was 8% in Caucasian patients and 14% in African-American patients in this subgroup of living-donor kidney transplant recipients. 5. The data demonstrate that the use of the living-donor transplant option is grossly underutilized. Estimates are presented that more than 11,000 living-donor kidney transplants should be possible in the US yearly.
