    Abstract:
    BACKGROUND: Renal transplantation is associated with several nonimmunological problems. Although urologic complications may be serious and carry a high risk of graft loss, they are amenable to successful treatment if diagnosed early and treated properly. Their incidence in the literature varies from 2.5% to 15%. OBJECTIVE: We sought to assess the incidence, pattern, management options, and outcomes of urologic complications in 560 consecutive renal transplantations performed at a single center between November 1993 and October 2004. PATIENTS AND METHODS: Twenty-one (16 male and 5 female) recipients developed posttransplantation urinary complications at 2 days to 76 months after renal transplantation. Their kidney grafts were obtained from 13 living and eight deceased donors. Complications included ureteric stricture in 11 and urine leak in 10 recipients. Ultrasonography and isotope renal scanning were the main diagnostic tools. Complications were treated either conservatively, by percutaneous dilatation and stenting, or by surgical reconstruction. RESULTS: The incidence of urologic complications following renal transplantation in the present series was 3.7%. All cases were successfully treated with no graft loss secondary to these complications. CONCLUSIONS: Posttransplantation urologic complications are associated with a good prognosis if diagnosed early and properly treated. Percutaneous transluminal dilatation of ureteric stenosis in renal transplant patients has good initial success, low morbidity, few recurrences, and long-term effectiveness.
