RESUMO
The morbidity and mortality rates of transplant nephrectomy are closely related to the indications of nephrectomy. This study evaluates the indications, etiology, and complications of graft nephrectomies for commercial kidney transplantation (CKT). Data were analyzed retrospectively for graft nephrectomies for CKT from January 2009 to December 2017 at the Royal Hospital, Muscat, Oman. Four hundred and three patients received CKT and 34 patients required a nephrectomy. Twenty-five patients had a nephrectomy within 10 weeks of CKT in the early group, and nine patients in the late group had the graft removed later than 10 weeks. Indications for nephrectomy in the early group were acute bleeding, infarcted kidney, and pyonephrosis in 7, 11, and 7 patients, respectively; in the late group, the indications were: pain, hematuria, fever, hypertension, and infection. Overall, seven patients had major blood loss, and those patients who had a pseudoaneurysm had tissue cultures that were positive for the fungus. Postoperative complications occurred in 26 patients. There was acute bleeding in three patients from the external iliac artery at the site of the previous anastomosis, and, in all three cases, the external iliac artery was ligated. There were 12 major wound infections, and three patients died from overwhelming sepsis and disseminated intravascular coagulation. Commercial transplants carry a high risk of immunological, vascular, and infectious complications, resulting in significant morbidity and mortality.

Transfusion related acute Lung injury (TRALI) though a serious blood transfusion reaction with a fatality rate of 5-25 % presents with acute respiratory distress with hypoxaemia and noncardiac pulmonary oedema within 6 h of transfusion. In non fatal cases, it may resolve within 72 h or earlier. Although reported with an incidence of 1:5000, its true occurrence is rather unknown. Pathogenesis is believed to be related to sequestration and adhesion of neutrophils to the pulmonary capillary endothelium and its activation leading to its destruction and leaks. The patient's underlying condition, anti-neutrophil antibody in the transfused donor plasma and certain lipids that accumulate in routinely stores blood and components are important in its aetiopathogenesis. Patient's predisposing conditions include haematological malignancy, major surgery (especially cardiac), trauma and infections. The more commonly incriminated products include fresh frozen plasma (FFP), platelets (whole blood derived and apheresis), whole blood and Packed RBC. Occasional cases involving cryoprecipitate and Intravenous immunoglobulin (IVig) have also been reported. We present a 15 year single institution experience of TRALI, during which we observed 9 cases among 170,871 transfusions, giving an incidence of 1:19,000. We did not encounter cases of haematological malignancy or cardiac surgery in our TRALI patients. Among the blood products, that could be related to TRALI in our patients included solitary cases receiving cryoprecipitate, IVIg, and recombinant Factor VII apart from platelets and FFP. All patients were treated with oxygen support. Six patients required mechanical ventilation. Off label hydrocortisone was given to all patients. There were no cases of fatality among our patients.
