Every year many patients with end stage function of kidney were done kidney transplantation surgery that could have different complications. Evaluation of complications of kidney transplantation (KTP) in three groups, live unrelated, related and cadaveric donors. We retrospectively studied 130 KTP in a 16 months period. Complication of Kidney was recorded according to type of donors. We had 67 live unrelated (group I), 16 live related (group II) and 47 cadaveric (group III) donors. We had 6 cases of recipients deaths (4 cases in group III and 2 cases in group I). We didn’t have early diuresis in 6 patients in three groups respectively (5 cases in group III and 1 cases in group I). Systemic and urinary infections were occurred in 10 patients (5 cases in group I, 4 cases in group III and 1 case in group II. Increased hematocrit treated by phelebotomy was observed in two cases and Lymphocele in 3 patients of group II were seen. Pulmonary edema was most common complication (3 cases of 4) in cadaveric group (group III). The major complications of KTP including lack of early diuresis and mortality are common in cadaveric KTP.
