The Value of Perfusion Fluid Culture Analysis in Deceased Donor Renal Transplants: A 10-Year Single-Center Experience

Microbiological analysis of kidney perfusion/transport solution is not routinely performed in all transplant centers. This paper gives a 10-year descriptive single-center experience of the routine culture of perfusion fluid in deceased donor renal transplant recipients as well as the prophylactic treatment of certain organisms if identified. Data were collected retrospectively on all deceased donor transplants performed between 2009 and 2018. Organisms detected were classified as either pathologic, of uncertain pathogenicity, or contaminants. Treatment was guided by the microbiology team. A total of 661 specimens were analyzed. Organisms were cultured in 168 of 661 (25.4%) of these samples. The most frequent organisms identified were skin and oral flora (n = 95, 42%). The majority of organisms identified (131 of 226, 58%) necessitated prophylactic treatment on the advice of our microbiology department. On 7 (4.2%) occasions, the perfusion fluid cultures grew organisms not covered by the routine antimicrobial prophylaxis, and on 15 occasions Candida albicans was isolated. Candida isolates were treated preemptively with 1 month of antifungal treatment. There were no infective sequelae in this group.
