Initial nonfunction in cadaveric renal transplantation.
Patients who receive a kidney transplant that does not function immediately have more complications and decreased graft survival than patients whose allografts function immediately. To determine the causes of initial nonfunction (INF), the authors reviewed 188 consecutive cadaveric kidney transplants performed between 1985 and 1988 at the University Hospital, London, Ont. Data were collected on 16 putative risk factors for INF, which were divided into three categories: donor, recipient and technical. INF was defined as the need for dialysis within 7 days of transplantation. Forty-eight (26%) of the 188 allografts had INF, 6 of which never functioned. Univariate analysis identified five variables associated with increased risk of INF: no donor dopamine use, back-table flush, single-organ retrieval, exchanged kidney and prolonged cold ischemic time. Multivariate analysis, however, identified only three variables associated with INF: cerebrovascular accident as the cause of donor death, no donor dopamine use and single-organ retrieval. The authors recommend (a) low-dose dopamine therapy for all donors and (b) multiorgan retrieval to produce quality kidneys for transplantation.
