Résumé : International audience
BACKGROUND: Infections of renal grafts with Candida species can induce life-threatening complications in the recipient. METHODS: A 9-year retrospective study involving all of the transplant centers in France was designed to determine the incidence, origin, characteristics, and outcome of graft-site candidiasis that occurred after kidney transplantation. Yeasts cultured from preservation or drainage solutions and graft specimens were recorded. RESULTS: Among 18,617 kidney grafts, 18 recipients corresponding to 12 donors developed culture-confirmed graft-site candidiasis (incidence, 1 case per 1000 grafts) a median of 25 days after the graft procedure. Clinical presentations included 14 cases of renal arteritis (13 were complicated by aneurysm), 1 urinoma, 2 graft site abscesses, and 1 surgical site infection. Candida albicans was involved in 13 cases. A unique C. albicans genotype or a single rare Candida species was involved in each episode. Together with the clinical history, these findings demonstrate that organ contamination followed by transmission to the recipient occurred during recovery. Therapeutic management varied from simple monitoring in 1 case to a combination of surgery (nephrectomy in 9 cases and arterial bypass in 9 cases) and antifungal therapy (14 cases). Overall, 3 of 18 kidney transplant recipients died, and 9 had their graft surgically removed. CONCLUSION: Graft-transmitted candidiasis that ends most often in fungal arteritis is associated with high morbidity and mortality after kidney transplantation and is related to organ contamination during recovery in the donor.

Résumé : International audience
We aimed to assess the impact of a postoperative drainage after RPN. A retrospective multicentric study included RPN performed at eight centers between 2010 and 2014. Three centers stopped using postoperative drainage early in their RPN experience, whereas other institutions systematically left a drain. Preoperative characteristics, complication rates, need for postoperative imaging or procedure (surgical or radiological) and length of hospital stay were compared between the two groups [drainage (D) and no drainage (ND)]. Among 636 RPNs, 140 were done without drainage (22 %). In the ND group, surgeons were more experienced (> 50 cases: 55.7 vs. 15.1 %; p < 0.0001), and tumors were more complex (RENAL score: 7.6 vs. 6.5; p < 0.0001). Complication rates were similar in both groups (21.9 vs. 20.2 %; p = 0.67). The omission of postoperative drainage did not increase requirement of CT scan (RR = 1.03; 95 % CI 0.64-1.67). Length of hospital stay was shorter in the ND group (4.5 vs. 5.5 days; p = 0.007). There were six urinary fistulas: four in the D group (0.8 %) and two in the ND group (1.4 %; p = 0.49). A CT scan was done to confirm the diagnosis of fistula in every case. In multivariate analysis, the omission of drainage was not associated with increased need of postoperative CT scan or major complications but was a predictor of decreased length of stay. The omission of postoperative drainage does not seem to increase the risk of postoperative complications and could safely be omitted after RPN.
