ABSTRACT
BACKGROUND: Multiple renal arteries in kidney grafts have been associated with an increased rate of vascular and urologic complications. Our objective is to compare the outcome of transplanted patients who receive a single pedicle kidney with those who receive a multiple arterial graft. OBJECTIVES: To find our the differences in the outcome and complications in patients undergoing kidney transplantation with one single artery or with multiple arteries. PATIENTS AND METHODS: We analyzed 147 kidney transplantations, (all performed in our hospital over a 3 year period). population divided into two groups: group A for those who presented with only one renal artery, or group B for those with more than one renal artery. Homogeneous vascular reconstructions and implantation rules were applied in all patients. We compared the rates of renal failure between the two groups, urinary and vascular complications, patient and graft survivals and the levels of creatinine clearance during the first year of post-transplantation. RESULTS: No significant differences were found between the two groups regarding to the values analyzed. CONCLUSIONS: As many other authors, we do believe that the presence of multiple renal arteries in kidney grafts should not be considered as a predictive factor of transplantation failure.
ABSTRACT
OBJECTIVE: Retrocaval ureter is a rare disease which is due to a abnormal development of the inferior cava vein. It usually presents with ureteral obstruction, and surgery is needed for symptomatic cases. METHOD: We present a case of retrocaval ureter and a revision of the literature. RESULTS: A 9 year-old boy who had consulted for macroscopic hematuria. The intravenous urography (IVU) suggested the diagnosis of retrocaval right ureter, which is confirmed by magnetic resonance imaging (MR). Make us resection of the retrocaval segment and relocation of the ureter anterior to the inferior vena cava. Follow-up IVU showed good resolution of hydronephrosis. CONCLUSIONS: Retrocaval ureter is a rare disease, with easy diagnostic and effective treatment. Other associated anomalies could be associated.

OBJETIVO: El uréter retrocavo es una patología poco frecuente debida a una alteración en el desarrollo embriológico de la vena cava inferior. Se manifiesta normalmente con clínica de obstrucción ureteral y el tratamiento en los casos sintomáticos, es quirúrgico.MÉTODO: Presentamos un caso clínico de uréter retrocavo y realizamos una revisión de la literatura.Palabras clave: Uréter. Anomalías genitourinarias. Vena cava inferior. Ureteroureterostomía.RESULTADOS: Paciente de 9 años que consulta por hematuria macroscópica. La Urografía intravenosa (UIV) sugiere el diagnóstico de uréter retrocavo derecho, lo que se confirma con estudio de resonancia magnética nuclear (RMN). Realizamos ureteroureterostomía y decruzamiento de vena cava inferior con buena evolución, confirmada por UIV.CONCLUSIONES: El uréter retrocavo es una anomalía fácilmente diagnosticable y con posibilidad de tratamiento eficaz. Debe evaluarse la posibilidad de otras malformaciones asociadas(AU)
