RESUMEN
PURPOSE: We review the indication, surgical technique and outcome of orthotopic renal transplantation. MATERIALS AND METHODS: The medical records of 1,000 patients who underwent renal transplantation at our institution between August 24, 1993 and August 1, 2000, as well as orthotopic renal transplantation were reviewed. RESULTS: Orthotopic renal transplantation was performed in 4 males and 1 female with severe iliac atherosclerosis or retained bilateral iliac fossa kidney transplant. Mean patient age was 56 years. There were 2 patients who received kidneys from living related donors, and 3 underwent cadaveric renal transplantation. Left orthotopic renal transplantation was successful in 4 cases, and 1 was converted to iliac fossa renal transplant because of a pulseless splenic artery and renal artery thrombosis after native renal endarterectomy. Orthotopic renal revascularization was done with splenic artery in 2, native renal artery in 2 and left renal vein in all 4 patients. Urinary tract reconstruction was performed with stented (2) or nonstented (2) ureteroureterostomy. Antibody induction, purine antagonists, calcineurin inhibitors and glucocorticoids were used for immunosuppression. Mean preoperative and 1-month postoperative serum creatinine was 7.9 and 1.3 mg./dl., respectively. Patient and graft survival was 100% during followup, which ranged from 6 months to 5 years. CONCLUSIONS: Despite the technical challenges, orthotopic renal transplantation in patients with unsuitable pelvic vessels can result in excellent patient and graft survival.
