Spontaneous renal allograft rupture is one of the most dangerous complications of kidney transplantation, which can result in graft loss. This condition needs immediate surgical intervention. Conservative management has dismal results. Its prevalence varies from 0.3% to 3%. Rupture occurs in first few weeks after transplantation. Predisposing factors for graft rupture are acute rejection, acute tubular necrosis, and renal vein thrombosis. There are growing reports about successful results of repairing these ruptured kidneys. In this study, we reviewed the medical records of 1682 patients who received kidney allografts from living donors from 1986 through 2003. There were six (0.35%) cases of renal allograft rupture. All were preceded by acute graft rejection. They were treated with antirejection medications. In first three cases, the kidney allografts were removed because the procedure of choice in this situation is graft nephrectomy; but in three next cases we repaired the ruptured grafts with good results in two of them. In conclusion, the procedure of choice for kidney allograft rupture is graft repair.
