title: Renal allograft rupture: surgical treatment by renal corsetage with lyophilized human dura.
abstract: We report 5 cases of renal allograft rupture in which diagnosis was established early through clinical data, laboratory tests and echography. Immediate surgery confirmed the suspicion in all cases. Acute rejection was present in 4 patients and in 1 the previous surgical puncture from the perirenal collection demonstrated serohematic fluid with a biological character similar to that of lymph. This latter case seemed to confirm the suspicion that any process associated with edema in a kidney with obstructed lymphatic tracts (meticulous lymphatic ligatures during donor extraction) is capable of causing a rupture. Conventional surgical treatment is dangerous and insecure on an edematous and friable kidney, resulting in a nephrectomy rate of 55.7 per cent and a postoperative death rate of 8 per cent. Hematoma evacuation, hemostasis by local compression and tridimensional containment of the ruptured areas should be the principles of this operation. By means of renal corsetage with lyophilized human dura these principles can be achieved. This surgical technique, which is simple and secure, its variations and future possibilities are described. In 3 of our 5 patients corsetage with lyophilized human dura was applied. All 5 grafts have taken. Renal function is good in 3 cases and acceptable in 2 at followup between 2 and 15 months.
