RESUMO
Chronic renal failure needs substitutive treatment such as haemodialysis and peritoneal dialysis for the patient to survive. Kidney transplantation (KTx) improves survival of the patient with chronic renal failure. Since the first KTx, performed by Merrill in Boston in 1959, advances in medical therapy, immunosuppressive therapy and refinements in surgical technique have improved the quality of life of the transplant patient. We present a review of the incidence, diagnosis and therapy of surgical complications after KTx reported in the literature and a retrospective analysis of 297 consecutive cadaveric donor kidney transplants done in our institution from September 1993 to September 2002. Vascular complications represent 5-10% of postoperative complications. Our experience showed an incidence of 1.7% renal artery thrombosis, 1.4% renal vein thrombosis, 1.7% renal artery stenosis, 1.4% arterial rupture due to fungal arteritis, 0.7% spontaneous graft ruptures and 12% lymphoceles. Urological complications account for 10-15% of postoperative complications. In our series we found an incidence of 7.4% urinary leakage, 2.7% urinary obstruction and 3% urinary reflux. Gastrointestinal complications represent 16% of postoperative complications. Our series showed 1% pancreatitis with an overall mortality of 33% and an incidence of 1.7% intestinal perforations. Surgical complications still represent a challenge that increments morbidity and mortality among kidney transplant recipients. Data shown may offer some guidance on how to deal with early and late post-transplant surgical complications.
